Rooming House Finance Australia: Residential or Commercial?
Property Lending
Co-living finance · Rooming house lending · Australia
The expensive mistake is solving the finance question after the contract is signed. Before you buy, convert or refinance, you need to know what the property is approved as, whether the standard residential valuation path is available, what income a lender will recognise and what happens if the valuation falls short.
Quick Answer
No national room-count or floor-area rule automatically makes a rooming house loan residential or commercial. But a purpose-built or approved boarding, lodging or rooming house sits outside the standard PropertyPRO residential valuation scope. That pushes many files toward an alternative, specialist or commercial path, with the final loan product still set by lender policy, approved use, security and borrower.
Also called: co-living property finance, rooming house finance, boarding house finance, finance for a house let by the room.

Is a co-living or rooming house a residential or a commercial loan?
No national room count, floor area or occupancy number automatically makes a rooming house loan commercial. The published boundary that matters first is narrower and more practical: the Australian Banking and Finance Industry Residential Valuation Standing Instructions version 4.1 put a property that is purpose-built or approved for boarding, lodging or rooming-house use outside the standard PropertyPRO residential valuation scope. That does not itself choose the mortgage product. It means the ordinary residential PropertyPRO valuation path is not the path for that approved use.
"Boarding houses (a property that is purpose built and/or approved for use as a boarding / lodging / rooming house)."
Australian Banking and Finance Industry Residential Valuation Standing Instructions version 4.1, section 2.4, Unsuitable / Out of Scope, effective 4 December 2023, read 1 September 2026. api.org.au. The quoted item defines the standard PropertyPRO valuation scope. It does not state that every rooming-house loan must use one particular credit product.
That distinction resolves the two answers you will see online. A small Class 1b building can still be an approved rooming house and therefore outside the standard PropertyPRO residential valuation path. A larger or more specialised building does not become a commercial loan because Australia has one national room-count trigger. Once the standard residential valuation route is unavailable, the lender has to decide which other valuation and credit pathway it accepts for the property.
"An ADI would, as a matter of good practice, develop a policy on when a borrower ... is more akin to commercial lending than residential lending."
Australian Prudential Regulation Authority, Prudential Practice Guide APG 223 Residential Mortgage Lending, dated 19 June 2025, read 1 September 2026. apra.gov.au. This is prudential good-practice guidance, not a rooming-house threshold. It explains why the final product boundary remains lender policy.
The useful question before you sign a contract is therefore not "is every rooming house commercial?" It is "can this exact approved use be accepted by the lender I am relying on, and what valuation path will that lender use?" A borrower pre-approval does not answer that property question. The property, its approved use and the lender's acceptable-security policy have to be checked separately.
The credit product is settled from the lender's policy and the property documents, not from the marketing label. If you want the background on how the two lanes behave once you are inside one of them, we have set out what changes when a property is assessed as commercial rather than residential, and separately what a loan to valuation ratio actually measures. Gearing on a commercial assessment is set by policy rather than by any published rule, which is the subject of our note on how far lenders will go on commercial security.
| Input | What the published or practical test says | What it changes | Who decides it |
|---|---|---|---|
| Approved use and standard residential valuation scope | A purpose-built or approved boarding, lodging or rooming house is out of scope for the standard PropertyPRO residential valuation instructions | The lender needs an alternative valuation and credit path; this is not by itself a rule naming the final loan product | The approval evidence and valuation instructions, then the lender's policy |
| Building classification | Class 1b and Class 3 are building classifications with different compliance consequences | Fire, access, egress and building obligations. A lower class does not prove a normal residential loan is available | A building surveyor |
| Room count and layout | There is no published national room-count threshold that changes the mortgage product | It can still matter where an individual lender's own security policy uses room count, configuration or marketability | The lender's own policy |
| How the rooms are let | One whole-of-dwelling agreement is a different use profile from separate room agreements | The applicable state regime, the income evidence and how vacancy risk is read | The owner, the agreements and the state regime that follows |
| Approvals and registration | Planning, building, registration and licensing are separate questions | Whether the current use and the income generated by it can be relied on | Local government, the state regulator and the building surveyor |
| Borrower and loan purpose | The same building can be presented by different borrowers for different purposes | Which credit products and regulatory pathway the lender can use; it does not change the building's approved use | Credit law, the borrower structure and the lender |
The most important separation is between valuation scope and loan product. ABFI v4.1 publishes a valuation-scope boundary for approved rooming houses. No primary source read for this guide publishes a national room count or floor area that automatically selects the mortgage product.
Where are you in the rooming house finance journey, and what should you solve next?
The search changes as the deal moves. Before contract the customer asks whether the property can be financed at all. Under contract they ask about valuation, deposit and time. After settlement they ask about compliance, refinancing, equity release and the next purchase. At exit they discover that the buyer has to finance the same specialised security. This page is organised so those questions connect rather than live as unrelated searches.
| Where you are | The question to solve now | What happens next |
|---|---|---|
| Reading a listing, project pitch or advertised yield | Is the use actually approved, and does the return survive the extra operating, compliance, finance and vacancy costs? | Check the state definition, approved use and cost section before treating the advertised yield as financeable income |
| Before making an offer or bidding at auction | Does the lender you are relying on accept this exact security and what valuation path will it use? | Get a property-specific security read and have your solicitor explain the contract position before you become unconditional. Borrower pre-approval alone does not answer the property question |
| Buying an existing operating rooming house | Do the approval, classification, registration, room agreements and rent roll all describe the same lawful use? | Build the approval and income file before the valuation is ordered so missing documents are found while there is still time to fix them |
| You own an ordinary house and want to convert it | What planning, building and tenancy changes come first, and does the existing loan need to be dealt with? | Confirm the intended use and building path before spending on works or assuming the present home loan can simply stay unchanged |
| Under contract with the finance clause running | Which valuation and credit lane applies, what cash contribution follows from that valuation, and which documents are still missing? | The lender assesses the property and borrower together; a specialist property can need more work than an ordinary borrower pre-approval allowed for |
| The valuation is below the purchase price | How will the cash gap be closed, and what does the contract allow while the finance date is still running? | Cash, other security, price renegotiation, another lender or short-horizon bridging may be considered, with the contract question put to the solicitor first |
| The lender has declined the file | Was the problem approvals, income, security policy, borrower structure or purpose? | Fix the cause rather than collecting blind applications. A documents problem, a serviceability problem and an unacceptable-security problem need different responses |
| Already operating and you want to refinance or release equity | What is the property worth now, what current room income will be recognised and does the present use fit the new lender? | Refinance or top-up is a fresh credit event with a contemporary valuation. Do not treat future equity release as a guaranteed deposit for the next purchase |
| A land-tax notice, compliance issue, insurance question or loan expiry has landed | Is the trigger tax, building, insurance or credit? | Route it to the right professional first. Those systems use different tests even though they all affect the same property's cash flow |
| Getting ready to sell | Who can buy the property with its present approvals and what will their lender do with the same security? | The same features that narrowed your finance can narrow theirs, so exit financeability is part of today's purchase decision |
Are you looking for a room, or for a loan on the building?
This is worth settling in a line, because the same words are searched by two entirely different people. If you are looking for somewhere to live, or you already live in a rooming house and want to know what you are entitled to, this is the wrong page and a finance broker is the wrong person. Those questions belong to the tenancy regulator in your state, which for two of the three states covered here is Consumer Affairs Victoria and the Residential Tenancies Authority in Queensland. Everything below is written for the person buying, converting, refinancing or selling the building.
The second thing worth settling is which word you are using, because the word usually reveals which state you are in and which regime you have walked into. These are not interchangeable and they are not marketing variations of one another.
| The term | What it is | Where it comes from |
|---|---|---|
| Rooming house | A term defined in state law, carrying a regime and minimum standards | Victoria, where the test counts people |
| Rooming accommodation | The equivalent defined term, tested on what the resident occupies rather than on a headcount | Queensland |
| Boarding house | Two separate things: a tenancy category triggered by a resident count, and a planning category that must be affordable housing in perpetuity managed by a registered community housing provider | New South Wales, where the two questions run on different tests |
| Co-living housing | A planning category carrying no affordability requirement. Elsewhere the phrase is a market term rather than a defined one | New South Wales planning, and general market usage everywhere else |
| Share house | Normally one tenancy agreement over a whole dwelling, with the residents sorting the rooms out between themselves | Ordinary usage. Not a lending or planning category |
| Co-living, searched by a resident | A room to rent. A different search entirely, and not the one this page answers | Market usage by residents and operators |
A building marketed under one of these words can be regulated under another. A lender reads the approval, not the listing.
What actually makes a property a rooming house, and why does the answer change by state?
A rooming house is defined by state law, and the three states verified for this guide each draw the line in a different place, using a different test, to decide a different thing. That is the whole reason the answer changes when you cross a border. There is no federal definition sitting above them, so a building that is a rooming house in one state may sit outside the equivalent regime in the next one without a single brick moving.
In Victoria, the test counts people. Consumer Affairs Victoria states that "A rooming house is a building where 4 or more people can live in rented rooms, some of which might be shared", on a page last updated 8 February 2023 and read 28 August 2026. In Queensland the test does not count heads at all. The Residential Tenancies Authority frames rooming accommodation around what the resident gets: a resident "has a right to occupy one or more rooms", "does not have the right to occupy the entire premises", "does not occupy a self-contained unit" and "shares common rooms and facilities with other residents". A room count only appears in Queensland in one situation, where the provider lives on the premises, and it is a threshold for coverage rather than a general definition.
New South Wales runs two tests that answer two different questions, and conflating them is the most common error we see. Under the Boarding Houses Act 2012 (New South Wales), section 5(2), boarding premises "are a general boarding house if the premises provide beds, for a fee or reward, for use by 5 or more residents (not counting any residents who are proprietors or managers of the premises or relatives of the proprietors or managers)". That is the registration and tenancy question. The planning question is separate and much sharper: on the New South Wales planning position, a boarding house "must be used for affordable housing in perpetuity" and "must be managed by a registered community housing provider in perpetuity", while "Co-living housing has no affordability requirement".
The difference between these categories is legal, not a matter of branding or market positioning. A boarding house in the New South Wales planning sense is not a premium or a budget version of co-living housing, and co-living housing is not a rebranded boarding house. They are different development types with different obligations attached in perpetuity, and a lender reading a file cares which one the approval actually says, not which one the marketing material says. If the building is student housing or specialist disability accommodation, different rules again apply and we cover those in the guides on student accommodation investment finance and NDIS and specialist disability accommodation finance.
| Jurisdiction | The test | Threshold | What it decides | Source |
|---|---|---|---|---|
| Victoria | A building where people live in rented rooms, some of which may be shared | Four or more people | Whether the rooming house regime and its minimum standards apply | Consumer Affairs Victoria, page updated 8 February 2023 |
| Queensland | A right to occupy one or more rooms rather than the whole premises, with shared facilities | No headcount in the core test; four or more rooms where the operator lives on site | Whether the rooming accommodation regime applies | Residential Tenancies Authority, Queensland |
| New South Wales, tenancy | Beds provided for a fee or reward | Five or more residents, excluding proprietors, managers and their relatives | Whether the general boarding house regime applies | Boarding Houses Act 2012 (New South Wales), section 5(2) |
| New South Wales, planning | Whether the development is a boarding house or co-living housing | Co-living may have as few as six private rooms, though most developments have many more | A boarding house must be affordable housing in perpetuity and managed by a registered community housing provider in perpetuity; co-living housing has no affordability requirement | New South Wales planning, page updated 17 July 2025 |
This table covers three states because they are the three where the definitions were verified against a live primary source for this guide. Other states and territories run their own regimes on their own tests. South Australia in particular surfaces on this search and is deliberately not covered here rather than silently absent, because no South Australian source was read for this build. Sources read 28 August 2026: consumer.vic.gov.au, rta.qld.gov.au, legislation.nsw.gov.au and planning.nsw.gov.au.
What changes when the building crosses into a higher classification?
Crossing from Class 1b into Class 3 changes the building and compliance obligations, but it is not the national mortgage boundary. Fire, egress, access and construction requirements can change with the classification. The standard PropertyPRO residential valuation issue is separate: ABFI v4.1 already puts a property purpose-built or approved for boarding, lodging or rooming-house use out of scope, regardless of whether a lender later chooses a residential, specialist or commercial credit product.
The classification itself is a building question, decided by a building surveyor against the National Construction Code, not by the lender. A credit team reads that classification together with the approved use, plans, registration and marketability. A lower classification can make the building simpler to comply with, but it does not prove the property fits a normal home-loan valuation path.
Class 1b and Class 3 are still important because they tell you what the building has to comply with and therefore what a conversion may cost. A proposed extra room can change classification, fire-safety work, feasibility and marketability even though there is no national room-count rule selecting the loan product. Where the works need staged funding rather than a term loan, that is development and construction finance territory. The separate question of whether the spend returns in the valuation is covered in our guide to valuation gaps on development work. Purpose-built rental at scale is covered separately in build to rent in Australia.
The two published classifications, in full
Class 1b
"class 1b is a boarding house, guest house or hostel that has a floor area less than 300 m2, and ordinarily has less than 12 people living in it."
Queensland Building and Construction Commission, building classes under the Building Code of Australia. Page last reviewed 30 September 2021, read 28 August 2026. qbcc.qld.gov.au. The definition continues with a second limb covering four or more single dwellings on one allotment used for short-term holiday accommodation.
Class 3
"A residential building, other than a Class 1 or 2 building, which is a common place of long term or transient living for a number of unrelated persons."
Queensland Building and Construction Commission, same page. Page last reviewed 30 September 2021, read 28 August 2026. qbcc.qld.gov.au. The source continues with examples including a boarding house, hostel and backpackers accommodation.
Both definitions are quoted from a state regulator's summary of the Building Code of Australia because the code authority's own clause text would not render to an automated read on the build date. The classification of any particular building is a matter for a building surveyor assessing that building, not for a broker and not for a lender. General information only.
If you already own the house and want to let rooms in it
The order of operations is what decides whether this goes well, and the finance question is not first in it. A conversion crosses a building line, a planning line and a tenancy line before it ever reaches a credit team, and each of those is answered by somebody else. Working it in the other direction, starting with what can be borrowed, produces a number built on a classification nobody has confirmed.
One item on that list is easy to miss and it is the one that lands on an existing owner rather than a buyer. There is already a loan over the property, written against a dwelling. Whether changing how that dwelling is used and occupied engages anything in that loan is a question for the lender who wrote it, and it is better asked before the work starts than discovered at a review. We are not saying it always does. We are saying it is a question worth putting in writing early, because the answer is not something you can read off this page or off a listing.
Projected room rent and a completed-property refinance are two different credit tests. Before the conversion is operating, the evidence may be an independent rental appraisal, a valuer's market-rent opinion or a management projection rather than a seasoned rent roll. There is no Australian rule requiring a lender to accept projected room-by-room rent, and the treatment is lender policy. After the conversion is complete and operating, a refinance can be assessed against the current approved use, actual room agreements and receipts, occupancy history and a fresh valuation. That still does not mean the cash spent on the conversion can automatically be released again.
| Step | Who answers it | What it decides |
|---|---|---|
| Does the intended use engage the state rooming house or rooming accommodation regime | The state test, set out in the section above | Whether registration, minimum standards and a licence come into play at all |
| What class will the building be once it is used that way | A building surveyor, against the National Construction Code | The fire, egress and access work required, which is a construction cost before it is anything else |
| Does the planning approval cover the actual use | Local government, and the state planning regime | Whether the income from that use is income a lender can rely on |
| Does anything in the existing loan turn on how the property is used or occupied | The lender that wrote the existing loan, in writing | Whether the current facility can stay as it is through and after the conversion |
| What will the completed building be worth, and on what basis | A valuer, selecting the approach | Whether the conversion spend comes back, which is a separate number from what it cost |
| What room income can be evidenced before the property is operating | The lender, using the appraisal or valuation evidence it accepts | Whether projected room rent can be used at all, and how it is treated in serviceability |
| When can the completed property be refinanced | The new or existing lender after completion | Whether the current use, actual income, valuation and borrower support a refinance or equity release |
| What can be funded, and in which lane | The lender, reacting to all of the above | The structure, and it is the last question, not the first |
Whether a particular conversion needs a particular approval, and what your existing loan documents actually say, are questions for a building surveyor, your planning lawyer and your own lender. This table sets out the sequence, not the answers.
What approvals and registrations does a lender want to see?
A lender wants evidence of every approval the property's actual use requires, and it wants them as separate documents rather than as one. Planning approval, building approval and registration are three different things granted by different bodies for different reasons, and holding one of them is not evidence of the others. Where an operator licence also applies, that is a fourth item.
If you are still before contract, the useful finance-ready pack is the property address and listing, floorplan, approved use, building classification, current registration or operator licence where applicable, room rent roll or appraisal, room agreements or management arrangement, and the contract if one exists. The point is not to lodge an application blindly. It is to find out whether the security fits a lender and what valuation path is required before you rely on the borrower pre-approval.
Victoria makes the point cleanly. Consumer Affairs Victoria states that "The licensing scheme does not change your obligations to register your premises with the relevant local council, in accordance with the Public Health and Wellbeing Act 2008", and adds that you do not need the licence to register the premises, nor the registration to be granted the licence. Two separate obligations, neither one a precondition of the other, on a page last updated 9 April 2024 and read 28 August 2026 at consumer.vic.gov.au. An applicant who produces a licence and assumes it covers the council position has produced half the file.
The honest version of what happens when the paperwork is not there is worth stating plainly, because it is the most common situation we are asked about. A property that is already being let by the room without the approvals to match is not simply a property with a missing form. To a credit team it is a property whose income cannot be relied on, because the use generating that income may have to stop. Some lenders decline it outright. Others will look at it on the security rather than the income, which usually means a specialist or private lending structure and a shorter horizon while the position is regularised. What almost never happens is a mainstream residential assessment on the room income as it stands.
Missing approval evidence is one of the most common decline reasons on this property type, and it is also the most fixable, because it is a documents problem rather than a policy problem. The valuation consequence of a specialised or approval-dependent use is a separate matter, and we have set out how lenders treat specialised security at valuation. Whether a particular approval is required for your property, and how to obtain it, is a question for your own planning lawyer or a building surveyor. This guide does not answer it.
| Item in the file | What a complete file shows | What gets the file sent back |
|---|---|---|
| Planning approval | An approval that names the actual use of the building | Planning approval for a dwelling, with the building let room by room |
| Building approval and classification | Building approval, and the classification the surveyor assigned | A classification that does not match how the building is now used |
| Council registration | Registration of the premises where the state requires it | Registration in a previous owner's name, unresolved at purchase |
| Operator licence | The licence where the state runs one, held separately from the registration | A licence produced as evidence of the council registration, or the reverse |
| Fire safety and compliance certification | Current certification for the classification the building holds | Compliance work identified in a report and left undone |
| Room agreements | Agreements that match the approved use, not a single whole-of-dwelling lease | Income evidence from a use the approvals do not cover |
Planning approval, building approval, registration and the operator licence are granted by different bodies for different reasons. Holding one is not evidence of the others, which is why each is listed as its own row. The same discipline applied across a whole acquisition file is set out in our accommodation acquisition lender document pack, which is written for the accommodation lane but the sequence transfers.
If the rooms are already let and the approvals are not in place
Deal with the approvals before you deal with the lending, because until the use is regularised there is no version of this where the income reads as reliable to a credit team. That order is not a preference, it is the only sequence that changes the outcome. Borrowing against the property in its current state is possible, but it is priced as what it is, and it is a holding position rather than a resolution.
The non-credit steps come first and most of them cost time rather than money: get a building surveyor to tell you what class the building actually is as it is being used, find out from the council what is registered and in whose name, identify which approvals are missing rather than assuming it is one form, and take the licensing question separately from the registration question because in at least one state they are separately administered. Only once you know the size of the gap is there anything useful to ask a lender, because until then nobody can tell you whether this is a paperwork problem or a construction problem.
If the lender has already said no
The useful question is which of the four inputs caused it, because a decline is not one thing and three of the four are fixable by somebody other than the lender. A file knocked back on missing approval evidence is a different problem from a file knocked back on the income, and both are different again from a file knocked back because the security itself sits outside that lender's policy. Being told no without being told which one is the most common reason people go round in circles.
| What the decline was really about | How it usually shows up | What changes it, and who by |
|---|---|---|
| The approvals | Questions about planning, registration, the licence or the classification that the file cannot answer with documents | Obtaining or regularising the missing item. Local government, the state regulator and a building surveyor, not the lender |
| The income | The rent roll is accepted as real but the assessed figure lands well under it, and serviceability fails on the assessed figure | Nothing on the property. Either the structure changes, or other income or a different lender policy carries it |
| The security | The property is outside that lender's policy for the asset type, whatever the numbers look like | A lender whose policy covers it, which usually means a specialist or private lender and a different price |
| The borrower or the purpose | The entity, the credit law position or the stated purpose puts the file in a lane the lender does not write | A structuring question for your accountant and solicitor before it is a lending one |
A decline is not a valuation of the property and it is not a verdict on the deal. It is one lender applying one unpublished policy to one file on one day. The same four inputs, worked through on larger accommodation files, are in our note on why banks decline big accommodation loans.
How do lenders assess income from individual rooms?
Lenders discount room income, and they discount it further than they discount rent from an ordinary tenancy. Per room rent is not taken at face value in any serviceability assessment we see, because the assessor is not asking what the rooms produced last month. They are asking what the property will produce through a period in which some of those rooms are empty.
The published starting point sits in the same prudential guide as the lane question, and it is the only rental shading figure in this guide with a source attached. The guide's own words are set out below. Read the second half of the sentence as carefully as the first, because that is the half that applies here: a property let room by room is, by construction, a property with a higher risk of non-occupancy than one let on a single agreement. Every room is its own vacancy event, every room turns over on its own timetable, and the letting effort repeats per room rather than per building.
What that means in practice is that the gap between the rent roll you can show and the income the lender will use is wider on this property type than on a standard investment property, and the wider gap is the point of the exercise rather than a lender being difficult. We have written separately on how rental income shading is actually applied, on how a portfolio of rental income reads to a lender, and on how a business owner's investment property income is assessed. All three explain the mechanics that this property type runs into at a sharper angle.
One thing this guide will not do is tell you what shading a particular lender applies. Those numbers are policy, they are not published, they differ between lenders, and they change. Anyone quoting you a single figure for this property type is quoting their own assumption rather than a rule.
Will a lender use projected room rent before the property is operating?
Sometimes, but a projection is not the same evidence as an operating history. A converted property that has not started operating may have an independent rental appraisal, a valuer's market-rent opinion, proposed room rates and a management plan. An operating property can add current room agreements, actual receipts and occupancy history. No published Australian rule requires a lender to accept projected room-by-room rent, and the lender still applies its own serviceability and security policy to whichever evidence it accepts.
| Stage | Evidence that can exist | What it can prove | What it cannot prove |
|---|---|---|---|
| Existing operating property | Current room agreements, rent roll, actual receipts and occupancy history | How the approved use is performing now | That a lender will use the gross rent without shading, or that every lender accepts the security |
| Conversion not yet operating | Independent rental appraisal, valuer market rent, proposed room rates and management plan | A reasoned estimate of the intended income | A trading history. The lender decides whether and how projected rent is used |
| Refinance after the property has operated | Current agreements and receipts, occupancy history, approvals and a contemporary valuation | The current operating position and current security value | That equity can automatically be released. LVR, repayment capacity and lender policy are re-tested |
The evidence gets stronger as the property seasons, but lender policy still decides what is usable. A rent roll is evidence, not an entitlement to a particular assessed income.
The one published figure on rental income
Minimum haircut on expected rental income
"prudent serviceability policies incorporate a minimum haircut of 20 per cent on expected rental income, with larger haircuts appropriate for properties where there is a higher risk of non-occupancy."
Australian Prudential Regulation Authority, Prudential Practice Guide APG 223 Residential Mortgage Lending, dated 19 June 2025, read 1 September 2026. apra.gov.au. The passage is prefaced in the guide by "In APRA's view", and it describes a minimum, not a maximum and not a standard rate.
This is guidance to lenders on what a prudent serviceability policy looks like. It is not a figure any individual lender has committed to, it is not the shading you will be assessed at, and no Switchboard shading percentage is stated anywhere on this page. Actual treatment depends on the lender's own policy and on your circumstances at the time of application. General information only, not financial advice.
How is a co-living or rooming house valued, and what does that do to your exit?
The first valuation question is which report path the lender can use. Under ABFI Residential Valuation Standing Instructions v4.1, a purpose-built or approved boarding, lodging or rooming house is outside the standard PropertyPRO residential valuation scope. Once the lender has selected an acceptable alternative valuation path, the valuer then selects the valuation approach appropriate to the asset. The professional protocol in force says no one approach or method applies in every circumstance and gives price information from an active market particular weight. That protocol is effective 1 January 2025 and was read 28 August 2026 at api.org.au.
That sentence has a consequence most owners meet only once, and usually at the wrong moment. If price information from an active market is the strongest evidence of value, then a property type with very few comparable sales has thin evidence at exactly the point the number matters. The valuer is not being conservative out of temperament. They are working with a shallower evidence base and reporting a range that reflects it.
The second consequence follows from the first. Money spent converting a dwelling to be let by the room is not automatically returned in the valuation. Conversion spend is reflected where the work is standard and where the market has priced it; it is not reflected simply because it was incurred. Furniture and fit out are usually excluded from the security altogether. So the cost of the conversion and the change in the valuation are two separate numbers that owners tend to assume are one, and the difference between them sits with the borrower, not the lender. The same mechanic, in a different setting, is what we described in the duplex valuation gap, and the general question of what a valuer is actually testing is covered in what a commercial valuation actually tests and in how specialised security is valued.
Worth clearing one thing out of the way, because the internet is full of it: the residential valuation standing instructions the banks work to contain no minimum floor area, no studio size rule and no one-bedroom size requirement for any property type. The version in force is 4.1, effective 4 December 2023, read 28 August 2026 at api.org.au. The square-metre floors quoted around this topic do not come from that document. Where they exist at all, they are individual lender policy, unpublished and changeable.
The exit is where all of this lands. The buyer pool for a building configured and approved for letting by the room is narrower than for an ordinary dwelling, and it is use-dependent, meaning a buyer has to want that use or has to want to undo it. A valuer can and does comment on marketability, and those comments feed back into what a lender will advance. If the property is being sold as an operating concern rather than as bricks, the vocabulary shifts again and going concern is the term you will meet.
| What the valuer looks at | Ordinary dwelling | Let by the room | Effect on the loan |
|---|---|---|---|
| Report and instruction path | Standard residential PropertyPRO can be available where the security is in scope | Purpose-built or approved boarding, lodging or rooming-house use is out of scope for standard PropertyPRO, so the lender must select another acceptable path | Property-specific security acceptance comes before the valuation method |
| Approach selected | Comparable sales, in almost all cases | The valuer selects it; no standard assigns one by property type | The basis of the number is not assumed |
| Comparable evidence | Deep and local | Thin, because few comparable sales exist | Wider valuation range and more caution |
| Conversion spend | Reflected where it is standard work | Not automatically returned | The gap between cost and value sits with the borrower |
| Furniture and fit out | Usually excluded | Usually excluded | Money spent here is not security |
| Buyer pool at exit | Broad | Narrower, and use-dependent | Marketability comments can affect the lend |
What people are actually asking when they ask about the cap rate
The question circulating on this property type is a vocabulary question wearing a numbers question's clothes. People ask what cap rate a rooming house is valued at, and the reason nobody answers it cleanly is that the question assumes a valuation approach has already been selected, which is precisely what no standard does. It is still worth knowing the words, because you will meet them in a valuation report and they change what the report is telling you.
| The term | What it is asking | What it needs to work |
|---|---|---|
| Comparable sales | What have similar properties actually sold for | A pool of genuinely comparable sales, which is exactly what this property type is thin on |
| Capitalisation of income, the cap rate question | What income does the property produce, and what multiple does the market pay for that income | Income the valuer accepts as durable, and evidence of what the market pays for it. Both are contested here |
| Summation, land plus improvements | What is the land worth, plus what have the improvements added | Evidence that the improvements added value, which is not the same as evidence that they cost money |
| Marketability commentary | How readily could this be sold, and to whom | Nothing extra. It is the valuer's judgement, and it feeds back into what a lender will advance |
No capitalisation rate, yield or per square metre figure appears anywhere on this page. The professional protocol quoted above assigns no approach by property type, so any single rate quoted for this asset class is somebody's assumption rather than a published rule. Ask the valuer which approach was selected and what evidence sat behind it, because that is the answerable question.
Is there a minimum room or floor size?
For lending, there is no industry-wide minimum room area or studio-size rule in ABFI Residential Valuation Standing Instructions v4.1. That is not the same as saying there is no legal minimum room size. State planning, building and rooming-house regimes can impose their own room-dimension or occupancy standards, and an individual lender can separately set a security-policy floor.
Ask three different questions and keep the answers separate: is the room lawful for the intended use, is the building appropriately approved and classified, and does the chosen lender accept the security? A room can satisfy the legal standard and still fall outside one lender's policy. A room can also satisfy a lender's size preference while the property fails an approval or valuation-scope test. The square-metre number alone never answers all three.
The valuation came back below the price. What happens now?
Five things can happen, and four of them are decided by you rather than by the lender, which is worth knowing before the panic sets in. A short valuation is not a decline. It is a smaller number, and every response is some version of closing the gap between that number and the price, either with cash, with other security, with a lower price, or with time. The one thing that almost never works is asking the same valuer to look again without new evidence.
Before any of that, one point is worth taking to your solicitor the same day, because it is the point most people get wrong. A subject to finance clause does not automatically rescue you from a low valuation. The clause responds to finance being approved or refused, not to the size of the number. If the lender is still willing to lend, just less, finance has been approved and the clause may never trigger, which leaves the shortfall as yours to fund. Whether that is how your particular contract works is a question for the person who read it, not for a broker and not for this page. The mechanics of a shortfall that surfaces later, at settlement rather than at the finance date, are set out separately in our guide to a valuation shortfall at settlement; this section deals with the version that lands while the finance clause is still running.
| The response | What it involves | What it costs you |
|---|---|---|
| Put in more cash | Reducing the amount drawn so the loan sits against the valuation rather than the price | The gap, in cash, at settlement. The cleanest option and usually the least available one |
| Add other security | Bringing another property into the security position so the gearing works across both | Encumbering an asset that was previously clear, and tying two properties together for the life of the facility |
| Renegotiate the price | Taking the valuation back to the vendor as evidence, before the finance clause expires | Nothing, if the contract still allows it. Everything, if the finance date has already passed |
| Go to a different lender | A different lender, a different valuer and often a different approach selected on the same building | Time you may not have, another valuation fee, and a second credit enquiry on the file |
| Bridge the gap on a short horizon | A second mortgage or a caveat facility covering the shortfall while the position is resolved | More than every option above it, and it needs an exit that is real and dated before it starts |
Which of these is open to you depends almost entirely on what your contract says and how much time is left on the finance clause, which is a question for your solicitor before it is a question for a broker. Nothing here is a recommendation of any one path.
Can you refinance a rooming house and use the equity to buy the next one?
Possibly, but equity is not the same thing as cash available to draw. APRA's current residential mortgage guidance says lenders should recalculate LVR at a top-up or other formal loan increase, use an appropriate contemporary valuation at refinance, exercise particular caution when equity is drawn down, and normally complete a full repayment-capacity assessment where the loan exposure increases significantly. The lender can then add its own cash-out, purpose, entity and total-exposure policy on top.
If the plan is to use property one to fund property two, both sides have to work at the same time. The first property must support the refinance or equity release, and the second property must independently fit a lender's acceptable-security and valuation policy. A high paper valuation on the first property does not solve a security-policy problem on the second. The general refinance mechanics are set out in our equity release and refinance guide.
| Gate | What is re-tested | Why the equity on a spreadsheet may not be available |
|---|---|---|
| Current security | Approved use, lender security policy and contemporary valuation | A new lender can classify or value the same property differently |
| Current LVR | The proposed loan against the fresh valuation | The lender's maximum gearing can leave usable equity below the owner's headline equity |
| Repayment capacity | Current income, shaded room rent, debts and expenses | A property can have equity while the borrower cannot support a larger loan |
| Cash-out and purpose | What the released funds are for and which evidence the lender requires | Lender policy can restrict or condition equity drawdown even at an acceptable LVR |
| Borrower and portfolio exposure | Entity, guarantees, existing debts and the lender's exposure to the borrower or asset type | A lender can cap exposure before the property-level equity is exhausted |
| The next property | Its own approval, classification, valuation path and acceptable-security position | Funding the deposit does not make property two financeable |
APRA's guidance is prudential guidance to regulated lenders, not a promise of a particular cash-out policy. Specialist and non-bank lenders can use different policies, and actual terms depend on the lender and borrower at the time.
Who buys one of these when you come to sell?
The buyer pool and the lending lane are the same question seen from the other end. Whatever narrowed your finance narrows your buyer's, because the person across the table has to get an approval on the same building, from a lender applying the same unpublished policies, on a valuation that will select the same contested approach. That is the part the returns arithmetic tends to leave out entirely.
| The buyer | What they are actually buying | What their lender will ask |
|---|---|---|
| Another operator | A running configuration, with the approvals, the classification and the residents already in place | Exactly what you were asked: what class the building is, what the approvals cover, and how much of the room income can be relied on |
| An investor intending to unwind the use | The building, on the assumption it can go back to being an ordinary dwelling | Whether it converts back, what that costs, and whether any obligation attached to the approval survives the sale |
| A developer or builder | The land and what can be built on it, largely disregarding the room income | Land value and end value, on a development assessment rather than an income one |
| A buyer able to carry a perpetual obligation | A building whose approval binds the use in perpetuity, which in New South Wales means a boarding house managed by a registered community housing provider | Whether the buyer can satisfy the obligation at all, which removes most ordinary investors from the pool before price is discussed |
No transaction volumes, days on market or price outcomes appear here, because no independent Australian dataset for this property type was found to support any of them. What can be said is structural: the approvals that make the income possible are the same approvals that decide who is able to buy it from you.
What do the published returns leave out?
There is no independent Australian dataset on net returns from co-living and rooming house property, and the figures circulating on this topic are published by parties selling either the product or the advice. That is not a criticism of any particular operator. It is a statement about what evidence exists, and the honest answer is that a comparable, independently collected net return series for this property type does not.
Because of that, this page carries no yield figure, no return figure and no vacancy assumption, not even to disagree with the ones in circulation. Repeating a number in order to argue with it puts the number on the page, and pages get quoted in fragments.
What can be said without a dataset is what the cost lines are, because those are structural rather than empirical. A building let by the room carries costs a single tenancy does not, and they are not rounding errors. Utilities and internet are usually the owner's rather than the resident's. Shared areas need cleaning on a schedule. Rooms come furnished, and furniture is consumed and replaced. Letting and management run per agreement rather than per building, so a building with many rooms carries many agreements, many turnovers and many arrears conversations. Compliance and fire safety obligations attach to the classification and recur. Insurance is priced on the use, not on the postcode.
The gap those lines create between a gross figure and what an owner banks is the thing to interrogate in any projection you are shown. The question to ask of a return figure is not whether it is high, it is which of these lines it is net of, and whether the answer is written down. A related pattern, where the headline number and the cash position diverge because the setup costs land before the income does, is one we wrote up in the landlord incentive gap. More broadly, the way we think about property lending sits across the property and development finance hub.
| Cost line | Let on one whole-of-dwelling agreement | Let by the room |
|---|---|---|
| Utilities and internet | Usually the resident's | Usually the owner's |
| Cleaning | No shared areas, the whole dwelling sits under one agreement | Shared kitchens, bathrooms and living areas, cleaned on a schedule |
| Insurance | Building insurance on ordinary residential terms | Priced on the use rather than on the dwelling |
| Letting and management | One letting fee and one management fee | Run per agreement, so many agreements to let and to manage |
| Agreements, bonds and arrears | One agreement, one bond, one set of arrears | Many agreements, many turnovers and many arrears conversations |
| Turnover | Measured in tenancies, not in rooms | Between rooms, running continuously |
This table carries only the lines where both arrangements can be stated. Council rates, water rates and repairs and maintenance to the building sit on the single-tenancy list. Furnishing every room and the compliance and fire safety obligations that attach to the classification arise on the by-the-room side and are described in the paragraph above. No figure is attached to any line here, because no independent Australian dataset supports one.
Insurance deserves one extra line, because it is the cost line most often assumed rather than checked. Whether an ordinary landlord policy responds to a building let room by room is answered in the product disclosure statement of the specific policy, and it varies between insurers and between products from the same insurer. There is no general answer, and a finance broker is not the person to give you one. Read the policy wording for the use, not for the building type, and put the question to an insurance broker who writes this class before you rely on cover you have not confirmed.
One thing worth knowing about those numbers before you weigh any of them. Every published return figure we have been able to trace on this property type traces back to somebody selling the asset: developers and builders marketing purpose-built stock, buyers' agents and project marketers placing it, and operators promoting the model. That does not make any individual figure wrong. It does mean there is no independent Australian dataset sitting behind the range, no regulator publishing it and no industry body collecting it, so a figure and its publisher have to be read together. Where genuinely independent research exists on this kind of housing, it is housing policy research into the experience of marginal rental accommodation rather than research into what an investor nets, which is a different question and does not answer this one.
How do land tax and goods and services tax apply?
Land tax and goods and services tax use separate tests, and neither test is decided by whether the lender calls the loan residential or commercial. GST asks what the premises are and how the accommodation is supplied. Land tax asks which state's rules apply and whether the property meets that state's concession conditions.
For GST, the safest answer is not "boarding house equals taxable" or "rooming house equals residential". Australian Taxation Office ruling GSTR 2012/6 specifically discusses rooming houses and says the features of the premises and operation have to be weighed to decide whether the property is, or is similar to, a hostel or other commercial residential premises. The ATO also says a state or territory boarding-house definition does not by itself determine the GST Act answer. It is an overall-impression test, and it belongs with your registered tax agent or accountant.
If the premises do fall inside the commercial residential category, the ATO's long-term accommodation rules then become relevant. The general ATO guidance describes accommodation of 28 continuous days or more as long-term and sets out different GST treatments depending on the facts. This page does not apply those treatments to a particular property.
For land tax, the current primary sources can now be stated. Victoria and New South Wales both publish conditional concessions for this accommodation use. They are not automatic because the property is called a rooming house or boarding house. Both current tests look at registration, long-term occupancy and tariff conditions, and both require evidence.
| State | Current published test | What the owner needs to verify | Primary source |
|---|---|---|---|
| Victoria | Land may be exempt where it is used and occupied as a registered rooming house primarily providing low-cost accommodation, with current eligibility including an 80% long-term-resident test for the previous tax year and a maximum-tariff condition | Current council registration, occupancy history, resident relationships, tariffs and the evidence required by the State Revenue Office | State Revenue Office Victoria, updated 15 June 2026, read 1 September 2026 |
| New South Wales | For the 2026 land-tax year, a registered boarding house can qualify where at least 80% of occupied accommodation meets the long-term-resident and tariff conditions, with an annual declaration required | Registration, occupancy records, long-term-resident status, tariffs, annual declaration and any partial-use calculation | Revenue NSW LT-119, current for 1 January to 31 December 2026, read 1 September 2026 |
This is a routing table, not tax advice. The concessions are conditional, the tariff limits change, and the same property can have a different answer in a different tax year or ownership structure. Confirm the current position with the relevant revenue office and your registered tax agent or accountant.
None of this changes the finance question, but it changes the numbers underneath it. A property whose holding costs assume a land tax concession it does not qualify for has a serviceability problem the lender will find at assessment rather than at settlement. Where the property is assessed on the commercial side, the broader picture is in our comparison of commercial and residential investment property, and the lending itself sits under commercial and investment property loans.
The published goods and services tax tests
A rooming-house label does not decide the GST result
ATO GSTR 2012/6 treats rooming houses as a facts-and-features question. The premises and operation are weighed to decide whether they are, or are similar to, commercial residential premises.
Australian Taxation Office, GSTR 2012/6, paragraphs 246 to 247 and the overall-impression test, read 1 September 2026. ato.gov.au. A state rooming-house or boarding-house label is relevant context but is not by itself determinative of the GST Act characterisation.
When accommodation is long-term
Accommodation is "considered long-term when the stays are 28 continuous days or more".
Australian Taxation Office, same page, page last updated 15 December 2022, read 1 September 2026. ato.gov.au.
The two concessional treatments
Either "full GST for the first 27 days" then "concessionary GST from day 28 onwards", or, for a property that is predominantly long-term accommodation, goods and services tax "on half of the normal GST-inclusive price of that accommodation from the beginning".
Australian Taxation Office, same page, page last updated 15 December 2022, read 1 September 2026. ato.gov.au. The same page also describes an input-taxed treatment, so these two are options within a wider set rather than the only paths.
These tests apply only once premises fall inside the commercial residential category, and whether yours do is a determination for your tax adviser. No goods and services tax registration threshold is quoted on this page. The long-term guidance page carries a December 2022 update date and the legal ruling is read alongside it. Tax positions can change. General information only, not tax advice.
From our broking, indicative
Across the enquiries we see on properties let by the room, the same things decide whether a file moves, and none of them is the interest rate. We have set them out as process rather than as numbers, deliberately.
- The questions arrive in a fixed order: what is the building classified as, what approvals are held, how are the rooms let, and who is borrowing. A file that cannot answer the first two rarely gets a serious look at the third.
- The document set expands the moment the property stops being an ordinary dwelling. Planning approval, building approval, the council registration and, where the state runs one, the operator licence are asked for as separate items, not as a single compliance pack.
- The most common thing that stalls these applications is evidence rather than policy. The property is already being let by the room and the paperwork for that use is incomplete, out of date or in a previous owner's name.
- Where the approvals are in order but the lending lane is genuinely unclear, the file is often better placed with a specialist or private lender that prices the security honestly than pushed at a residential policy it does not fit.
Indicative only, drawn from enquiries and deals we have placed, as at 1 September 2026. Not a quote and not an offer. No approval time band, gearing band, deposit band or return figure is stated here, because we have not set an authorised band for this property type and the ranges circulating publicly are not ours. Actual terms depend on lender policy and your circumstances at the time of application. General information only, not financial advice.

This evidence index separates what each source actually decides. Some sources were first read 28 August 2026 and the valuation, GST and land-tax sources were re-read or added on 1 September 2026. A published valuation-scope rule is not presented as a mortgage-product rule, and a tax concession is not presented as automatic eligibility.
The recurring mistake is treating "residential or commercial?" as one test. It is several tests that travel together. A building surveyor decides the classification. Planning, registration and licensing determine the lawful use. ABFI valuation instructions determine whether the standard PropertyPRO residential valuation path is in scope. A valuer determines the supported value under the lender's chosen instructions. The lender then decides which credit product it will write for the property and borrower. No primary source read for this guide publishes one national room-count or floor-area number that automatically makes the loan commercial.
Key takeaway: approve the property before you rely on approval of the borrower. Confirm the use, valuation path and lender security policy before you become unconditional.Frequently Asked Questions
Not automatically. No national room-count or floor-area number makes the loan commercial. But ABFI Residential Valuation Standing Instructions v4.1 put a property purpose-built or approved for boarding, lodging or rooming-house use outside the standard PropertyPRO residential valuation scope. That does not itself select the loan product; it means the lender needs another acceptable valuation and credit path. The final product depends on lender policy, approved use, security, borrower and purpose.
No, and the difference is legal rather than descriptive. A share house is normally one tenancy agreement over a whole dwelling, with the residents sorting the rooms out among themselves. A rooming house is a building where the residents each have a right to occupy a room rather than the whole premises, which is what brings a state rooming house regime into play. In Victoria that regime engages where four or more people can live in rented rooms; in Queensland the test is about what the resident occupies rather than how many people there are. It is the same distinction that separates ordinary residential lending from the specialised assessments described in our guide to student accommodation investment finance.
In New South Wales they are two different planning categories with different obligations, and that is the difference that matters. Under the New South Wales planning position, a boarding house must be used for affordable housing in perpetuity and must be managed by a registered community housing provider in perpetuity, while co-living housing has no affordability requirement. Elsewhere, "co-living" is largely a market term while "rooming house" is a defined term in state law, so the same building can be marketed as one and regulated as the other. Purpose-built rental at scale is a third thing again, covered in our guide to NDIS and specialist disability accommodation finance where the use is specified rather than chosen.
There is no published universal rooming-house deposit percentage. Work backwards from the lender's loan-to-value limit against its valuation, not just from the purchase price. Because an approved rooming house can sit outside the standard PropertyPRO residential valuation scope, establish the lender and valuation path first. If the valuation is below the contract price, the cash contribution rises even where the borrower's serviceability would support a larger loan. The deposit is not the same thing as total cash to settle. State transfer duty, conveyancing and legal costs, valuation or lender costs where applicable, and any valuation shortfall sit outside the simple LVR calculation unless they are funded separately.
A normal borrower pre-approval does not prove that a rooming house can be financed through the same home-loan path. Under ABFI v4.1, a purpose-built or approved boarding, lodging or rooming house is outside the standard PropertyPRO residential valuation scope. Some lenders may have another residential or specialist pathway and others may assess it commercially. Check the exact property, approved use and valuation route before you rely on the pre-approval.
Class 1b is a building classification, not a type of business. The Queensland Building and Construction Commission describes class 1b as "a boarding house, guest house or hostel that has a floor area less than 300 m2, and ordinarily has less than 12 people living in it", on a page last reviewed 30 September 2021. Above that, the building is Class 3, which is described as a residential building that is a common place of long term or transient living for a number of unrelated persons. The classification is assigned by a building surveyor, not by a lender, and crossing between the two changes what the building must comply with and usually what it can be funded as. Purpose-built rental developments are covered in our guide to build to rent in Australia.
In most cases you need more than one approval, and they are separate obligations. Planning approval, building approval and council registration are granted by different bodies for different reasons, and holding one is not evidence of the others. Victoria is the clearest example: Consumer Affairs Victoria states that the operator licensing scheme "does not change your obligations to register your premises with the relevant local council", and that neither one is a precondition of the other. Whether a specific approval applies to your property is a question for your planning lawyer or building surveyor. Where approvals are incomplete and the property is already let by the room, the funding conversation usually moves toward specialist or private lending until the position is regularised.
They discount it, and typically by more than they discount ordinary rent. The prudential guide on residential mortgage lending states that prudent serviceability policies incorporate a minimum haircut of 20 per cent on expected rental income, with larger haircuts appropriate where there is a higher risk of non-occupancy, in a guide dated 19 June 2025. Letting by the room is precisely a higher non-occupancy risk profile, because each room vacates independently. The actual shading applied is each lender's own unpublished policy, and the mechanics are set out in how rental income shading is applied.
Not automatically. Australian Taxation Office ruling GSTR 2012/6 says rooming houses require a facts-and-features assessment to determine whether the premises are, or are similar to, commercial residential premises, and a state-law boarding-house or rooming-house label does not decide the GST result by itself. If the premises fall inside that category, separate long-term accommodation rules can then apply. Confirm the treatment of your property with your registered tax agent or accountant.
Yes, but refinance is a fresh assessment of the property's current use rather than a continuation of the original loan decision. The lender re-tests the approvals, current room income, security policy and a contemporary valuation. If the property was originally financed as an ordinary dwelling and later changed use, whether that change affects the existing loan is a question about the current loan terms; read those terms and obtain legal advice where needed before assuming the consequence.
The loan is written against the valuation rather than the price, so the difference becomes cash you have to find. From there five responses exist: put in more cash, add other security, take the valuation back to the vendor and renegotiate while the finance clause is still running, move to a lender whose valuer may select a different approach, or bridge the gap on a short horizon with a second mortgage or caveat facility. Which of them is actually open to you depends on your contract and on how much time is left on the finance date, which is a question for your solicitor first.
Possibly, but it is a planning and building question before it is a finance question. First establish whether the intended use engages the state rooming-house regime, what classification and works a building surveyor requires, and whether planning or registration obligations apply. Then check the loan already sitting over the dwelling rather than assuming it can stay unchanged after the use changes. Only after those answers are known is there a reliable question to put to a new lender.
A common reason is that the standard residential valuation route may not fit the security. ABFI v4.1 lists purpose-built or approved boarding, lodging and rooming houses as out of scope for standard PropertyPRO residential valuation. From there lenders can still differ: one may have a specialist or commercial path while another may not accept the security. Missing approvals, shaded room income, borrower structure and purpose can also cause a decline. One lender's no is therefore a policy decision on one file, not a universal verdict on the property.
It can. A refinance or top-up is a second credit event, not an automatic release of the equity shown on a spreadsheet. APRA's current guidance says LVR is typically recalculated at a top-up or refinance using an appropriate contemporary valuation, and a significant increase in exposure would normally trigger a full repayment-capacity assessment. The lender also re-tests the current use, approvals, room income, existing debts and its own cash-out and exposure policy. If the released equity is meant to fund the next rooming house, the refinance and the next property's security approval both have to work.
For lending, ABFI v4.1 does not publish an industry-wide minimum room area or studio-size rule. That is different from legal room-size requirements: state planning, building and rooming-house regimes can impose their own dimensions, and an individual lender can separately set a security-policy floor. Ask three questions: is the room lawful, is the building appropriately approved and classified, and does the chosen lender accept the security?
Realistically four kinds of buyer: another operator taking on a running configuration, an investor who intends to unwind the use back to an ordinary dwelling, a developer buying the land and what can be built on it, and, where the approval binds the use in perpetuity, only a buyer able to carry that obligation. The buyer pool and the lending lane are the same question from the other end, because your buyer has to get an approval on the same building from a lender applying the same unpublished policies. Whatever narrowed your finance narrows theirs.
Potentially, but the borrower structure and the property security are two separate gates. A company or trust can change the borrower, guarantees, servicing treatment and lender universe. An SMSF borrowing to acquire property generally uses a limited recourse borrowing arrangement and adds separate superannuation-law and specialist-lending requirements. None of those structures makes an unacceptable rooming-house security acceptable. Set the ownership structure with your accountant, registered adviser and solicitor before contract, then test the exact entity and exact property against lenders that accept both.
