Low doc commercial property loans: which income path fits, what LVR is possible and what happens next

Low doc is not one product and it is not one universal lender ladder. This guide compares the main Australian assessment paths for self-employed commercial property borrowers, including full doc, alt or lite doc, specialist declaration-based pathways and lease doc. It also covers owner-occupied versus investment property, current LVR and term ranges, valuation shortfalls, settlement cash, refinance and what happens after approval.

Quick Answer

Low doc commercial lending is a group of assessment paths, not one product. Full doc uses lodged financials, alt or lite doc uses alternative income evidence such as BAS or business bank statements, some specialist lenders offer declaration-based pathways, and lease doc can use arm's-length rental income instead of the borrower's own trading income. Published Australian products reviewed on 30 September 2026 reach up to 80 per cent LVR on some full, alt and lease-income products, but the available LVR and term depend on the lender, property, loan size, location, tenant and evidence.

Also called: low doc commercial finance, alt doc commercial lending, lite doc commercial lending, mid doc at some lenders, or lease doc when an arm's-length commercial lease carries serviceability. The labels are not standardised across every lender, so compare the evidence test, LVR, term and security rather than relying on the product name alone.

What do full doc, alt doc, specialist quick doc and lease doc mean?

They are different ways a commercial lender can test repayment capacity, not four universal industry-standard rungs. Full doc uses lodged tax returns and financial statements. Alt doc or lite doc uses alternative evidence such as BAS, business bank statements or other lender-accepted documents. Some specialist lenders also offer lighter declaration-based pathways. Lease doc is different again: an arm's-length commercial lease and its rent can carry the serviceability test instead of the borrower's trading income.

Low doc does not mean no checks. The lender still verifies identity, credit conduct, the borrowing entity, ATO position where required, the security property and the valuation. The label on the product matters less than what evidence the lender accepts, what LVR it allows, what term it offers and what security it will take.

How the main commercial property assessment paths differ in Australia (30 September 2026)
Assessment pathHow repayment capacity is shownWhere it is commonly foundWhat usually limits it
Full docLodged tax returns and financial statements, plus current liabilities and ATO position as requiredBanks and non-bank lendersServiceability from the lodged numbers, property policy and valuation
Alt doc or lite docDeclared income supported by lender-accepted alternatives such as BAS, business bank statements, recent financials or other evidenceMostly non-bank and specialist commercial lendersHow well the evidence reconciles, ABN or GST history, property type, location and LVR
Specialist declaration-based pathwayA signed income declaration with little or no supporting income evidence, where a lender offers that pathwaySpecialist non-bank lendersLower leverage, narrower property policy and stronger reliance on the security and overall file
Lease doc or lease-incomeAn active arm's-length lease and the rent it produces; the borrower's own business income may not be the serviceability testSome banks and non-bank lendersTenant, lease term, interest cover, ownership structure, property type, location and valuation

Source check: current published Australian commercial lending material reviewed 30 September 2026 shows materially different product structures across lenders, including lease-income products that can reach 80 per cent LVR and 30 years, while other lease-doc products cap lower or tie the term to the lease. See the current bank lease-doc example, non-bank lease-income example and non-bank lease-doc example to 75 per cent and 30 years. Product policy can change.

Does low doc mean bad credit?

No. Low doc describes how income is verified, not the borrower's credit quality. A borrower can have clean credit and still need alt doc because the latest lodged return does not reflect current trading. Credit history, repayment conduct, ATO position, security and serviceability are assessed separately.

For the loan itself, start with how commercial property loans work overall. For the loans we arrange, see commercial property loans.

Which lender types use each assessment path?

Banks are strongest in full doc and selected lease-doc structures, while alt doc and lighter declaration-based commercial lending is concentrated in non-bank and specialist lenders. The exact labels differ, so the useful comparison is the evidence test and policy rather than the product name.

  • Major banks: full doc; several publish a lease doc product for tenanted commercial property.
  • Larger non-bank lenders: full doc and alt doc (lite or mid doc), often with terms to 30 years; at least one also publishes a lease-income product to 80 per cent LVR.
  • Specialist non-bank lenders: add declaration-based pathways and lease doc, usually at lower LVRs than their full doc products.
  • Private lenders: short-term, security-led loans that are a different product and sit outside this guide.

The shift toward non-bank lenders is visible at system level. The Reserve Bank's Financial Stability Review of March 2026 notes that non-bank lenders and private credit firms have increased the availability of credit for both housing and business borrowers (rba.gov.au, Financial Stability Assessment, March 2026).

In the deals we see, the lender type decides which rungs are open to you before the documents do. A non-bank lender sets its own documentation policy, and our matrix records what non-bank lenders accepted this quarter. For how the lender tiers stack up on a commercial file, and why a bank declines a self-employed file, those pages go further; if you are already there, read what to do after a bank says no.

From the broking desk, indicative only, as at September 2026

Basis: Switchboard panel records, May to September 2026, as published in our non-bank lender policy matrix.

  • Time to formal approval. Commercial property files typically take two to six weeks. Observed service levels ran from about six business days on a priority file to around 35 days. A lighter documentation level is not faster by default; the valuation usually sets the pace.
  • LVR the panel wrote. 75 per cent is the metro standard on standard commercial security. 80 per cent appears only in defined metro postcodes and up to about $3 million. Around 65 per cent is typical above about $4 million or on specialised security.
  • What declines these files: interest cover below the lender's minimum on net rent; a related-party lease with no evidence the business needs the premises and can pay the rent; BAS totals that do not reconcile with bank deposits or the accountant's letter; a lease with less time left than the lender's minimum.

These are ranges we have seen on files, not what you will be offered. Your LVR, term and approval time depend on the property, the lease, your income evidence and the lender. Indicative only, not a quote, an offer or an approval likelihood, and not financial advice.

Does owner-occupied or investment property change the low doc path?

Yes. It is often the first fork in the file. If your own trading business will occupy the premises, the lender usually assesses the business income, so full doc or alt doc is the natural path. If an unrelated tenant occupies the property, a lease-doc or lease-income path may be available because the external rent can be tested instead.

Which income source carries the loan?
Property situationIncome the lender is likely to testDocumentation path to investigate first
Your own business occupies the whole propertyThe trading business and borrower groupFull doc or alt doc
Unrelated tenant occupies the propertyThe lease income, tenant and lease term, or a combination of rent and borrower incomeLease doc, lease-income or full doc investment lending
Your business leases from your own trust or companyUsually the underlying trading business rather than treating internal rent as independent third-party incomeFull doc or alt doc unless a lender expressly accepts the related-party structure
Part owner-occupied and part leasedA blended assessment can be neededLender-specific commercial assessment

One current Australian bank lease-doc product requires an active arm's-length lease and says related-party lease income does not qualify under that pathway. That does not mean every lender has identical rules, but it is a strong reason not to create an internal lease and assume it turns an owner-occupied property into lease doc. See owner-occupied versus investment commercial property for the deeper split.

How much can you borrow with low doc or lease doc?

There is no single low-doc LVR ceiling. Current published Australian products reviewed on 30 September 2026 reach up to 80 per cent LVR on some full-doc, alt-doc and lease-income commercial loans. Other lease-doc products publish 65 or 70 per cent ceilings, and specialist declaration-based pathways can step down further. The actual limit depends on loan size, property type, postcode, valuation, tenant, lease and how much income evidence supports the file.

What LVR can each documentation path reach? Current published examples reviewed 30 September 2026
Assessment pathPublished ceiling seenWhy your file can come in lower
Full docUp to 80 per cent on some non-bank commercial productsLoan size, location, property type, serviceability and valuation
Alt doc or lite docUp to 80 per cent on some non-bank commercial productsStrength and recency of alternative income evidence, location, property type and loan size
Specialist declaration-based pathwayOften below the strongest full and alt doc ceilingsLimited supporting income evidence means the lender leans harder on leverage, security and exit
Lease doc or lease-incomePublished examples reviewed range from 65 per cent to as high as 80 per centTenant, lease expiry, interest cover, ownership structure, security, postcode, loan amount and valuation

Primary-source examples: one current bank lease-doc product publishes up to 65 per cent LVR, another bank up to 70 per cent, one non-bank lease-doc product up to 75 per cent on loans to $3 million, and one non-bank lease-income product up to 80 per cent. See 65 per cent bank example, 70 per cent bank example, 75 per cent non-bank example and 80 per cent lease-income example. These are product examples, not promises of what your file will receive.

Does location or loan size change the LVR?

Yes. Commercial lenders can set different maximums by postcode category, property type and loan size. A headline 80 per cent product does not mean every warehouse, shop, office or regional property qualifies at 80 per cent. The valuation can also become the binding number because the lender usually applies its LVR to the lower of the contract price and its accepted valuation.

Which property or lease features can reduce the available LVR?
Property or lease featureWhat it can change
Standard metro warehouse, office or retailUsually the broadest lender choice, subject to the specific postcode, loan size, valuation and borrower evidence
Regional propertySome lenders reduce maximum LVR, narrow acceptable postcodes or cap the loan amount
Specialised or single-purpose propertyCan reduce LVR or lender choice because resale and reletting risk is harder to assess
Vacant propertyLease doc normally cannot rely on rent that is not being paid, so another assessment path may be needed
Short lease remainingCan shorten the facility term, reduce lender choice or make a lease-doc structure unavailable
Single or weaker tenantMakes tenant quality, lease expiry and interest cover more important to the credit decision
Related-party tenantMay not qualify as true arm's-length lease doc, so the lender can look through to the operating business
Valuation below contract priceCan reduce the loan immediately because the lender usually applies the LVR to the lower accepted value
Illustrative: an electrician's company buys a light-industrial unit on alt docA company buys a $900,000 unit and its latest lodged returns lag current trading. At 75 per cent LVR the loan is $675,000 and the equity gap is $225,000 before duty, fees and any GST. At 80 per cent LVR the loan would be $720,000 and the equity gap $180,000, but the property, postcode, loan size and evidence still have to fit that lender's 80 per cent policy. Illustrative arithmetic only, not a quote.

See when 80 per cent commercial LVR is realistic and how much deposit a commercial purchase can require.

Can low doc be used to buy, refinance or release equity?

Yes, depending on the lender and property. Current Australian low-doc and lease-doc product pages include purchase and refinance, and some also allow equity release. The documentation path does not only matter when you are buying. It can also matter when your existing bank loan matures, your business needs cash from a property you already own, or you want to refinance a higher-cost facility once your evidence improves.

What changes by loan purpose?
What you are doingWhat the lender focuses on next
Buying owner-occupied premisesBusiness income evidence, contract, valuation, GST treatment and cash to settle
Buying a tenanted investmentLease, tenant, rent, lease expiry, valuation and ownership structure
Refinancing an existing commercial loanCurrent balance and conduct, valuation, income or lease evidence, remaining term and any exit fees
Releasing equityPurpose of funds, new LVR, serviceability or lease cover, property policy and lender-specific cash-out rules

For a refinance, do not compare the new rate in isolation. Check discharge fees, deferred facility fees, valuation and legal costs, and whether the refinance resets an interest-only period or changes covenants. If the original low-doc loan was a bridge while your returns caught up, the cleaner exit can be a later full-doc refinance.

How much cash do you need on top of the deposit?

Budget for more than the equity gap. A commercial purchase can require the gap between the loan and purchase price, transfer duty, GST where the contract is taxable, lender and valuation fees, legal costs and settlement adjustments. Because the lender commonly sizes its advance from the lower of the price and accepted valuation, a valuation shortfall can increase your cash requirement even when the contract price does not move.

What can you need to fund yourself on a commercial property purchase?
Cash itemWhat sets itWhen to confirm it
Equity gapLoan amount after LVR and valuationBefore finance approval and again after valuation
Transfer dutyState or territory law and transaction valueBefore exchange, using the relevant revenue office calculation
GST if the sale is taxableContract and GST lawBefore signing, with your accountant and solicitor
Valuation, lender and legal feesLender, valuer and advisersAt application, not the day before settlement
Settlement adjustments and working capitalContract, outgoings and what the business needs after settlementBefore committing all available cash to the deposit

What happens if the valuation is below the purchase price?

The contract price does not automatically fall, but the lender's advance can. If you agree to pay $2,000,000 and the lender values the property at $1,850,000, a 70 per cent LVR produces a maximum loan of $1,295,000. You then need $705,000 toward the price before duty, fees and any GST. If the valuation had matched the $2,000,000 price, the same 70 per cent LVR would have produced $1,400,000, so the valuation shortfall adds $105,000 to the equity you must find.

That is why the valuation is not an administrative formality. It can change the finance structure after you have already negotiated the purchase. See commercial property deposit and valuation shortfalls for the broader cash calculation.

Do you pay GST when you buy commercial property?

It depends on the transaction. A commercial property sale can be taxable, and GST-free treatment as a supply of a going concern only applies when the statutory conditions are met. The ATO says the purchaser must be registered or required to be registered for GST, the parties must agree in writing that the supply is of a going concern, and the vendor must supply all things necessary for the continued operation of the enterprise and carry it on until supply. A property sale by itself is not automatically a going concern.

A tenanted property can qualify where the leasing enterprise is genuinely being supplied and the conditions are met, but do not assume every tenanted sale is GST-free or every vacant sale is taxable in the same way. Your accountant and solicitor should settle the treatment before you exchange because it can materially change settlement cash. See the ATO's going-concern property guidance.

If GST is payable, lenders commonly size the loan without it, so plan to fund the GST at settlement and recover it as a credit through your BAS. Some specialist lenders market short-term GST funding for commercial settlements, repaid when the credit comes back; it is a separate facility with its own cost, so price it before relying on it.

Transfer duty is separate and varies by state or territory. Business.gov.au notes that property transfers can attract duty and directs buyers to the relevant state or territory revenue office. See current stamp duty guidance.

Can a low doc or lease doc commercial loan run for 30 years?

Yes. Current Australian non-bank products reviewed on 30 September 2026 publish terms of up to 30 years on low-doc commercial lending and on some lease-income commercial lending. But lease doc does not have one universal term rule: another current bank product caps the term at five years or lease expiry, whichever is shorter, while other non-bank lease-doc products publish terms of up to 30 years with lower maximum LVRs as the loan grows.

What can set the term on a low doc or lease doc commercial loan?
Assessment pathLong term available?What can cap itWhat to check before choosing
Full docUp to 30 years on some non-bank productsLender policy, borrower age or entity policy where relevant, property and purposeAmortisation, interest-only period, reviews and exit costs
Alt docUp to 30 years on some non-bank productsLender policy, property and evidenceWhether a longer term costs more and whether you expect to refinance to full doc
Lease doc or lease-incomeCan be up to 30 years on some productsOther products tie term directly to lease expiry or cap it at five yearsFirm lease term, options, tenant, ICR, review points and refinance risk at maturity

Primary-source examples: one current non-bank lease-income product publishes a 30-year maximum term, while a current bank lease-doc product publishes up to five years or lease expiry, whichever is shorter. See 30-year lease-income example and lease-linked bank example.

Illustrative: a self-employed investor wants the lowest required repaymentIf a 30-year lease-income product fits the property, tenant and LVR, the contractual repayment can be spread much longer than on a five-year bank lease-doc structure. That does not automatically make it cheaper: compare rate, fees, interest-only loading, covenants and how long you actually expect to hold the loan. Illustrative only.

For how interest-only periods work and how lease expiry affects commercial finance, those guides go deeper.

What does a lease doc lender need from the lease?

The lender needs evidence that the rent is real, independent enough for the product, durable enough for the proposed term and sufficient to cover the debt test. Current product rules differ, but the common questions are who the legal tenant is, whether the lease is active and arm's length, how much firm term remains, what net rent is available after outgoings and whether the interest cover ratio meets policy.

  1. An executed, current lease. The lender wants the actual legal agreement, not an agent's marketing summary.
  2. A tenant the product accepts. Some published lease-doc products require an arm's-length tenant and do not accept related-party rent.
  3. Enough lease term. Some products link the loan term directly to lease expiry; others can offer longer contractual terms but still assess lease quality and expiry risk. One non-bank lease-doc guide we reviewed wanted 24 months remaining at settlement.
  4. Enough rent. One current bank product publishes a minimum ICR of 1.5 times. Other lenders use their own ICR or debt-service test.
  5. An acceptable ownership structure and security. Some bank products also prescribe the borrowing vehicle and take additional security or guarantees.

Do not assume so. One current Australian bank lease-doc product expressly requires an arm's-length lease and says related-party lease income does not qualify. Other lenders can have different policies, but an internal lease does not automatically become independent external cash flow. If your own trading business occupies the premises, prepare for the lender to assess the business itself under full doc or alt doc.

What interest cover does a lease doc lender want?

It is lender-specific. A current published bank lease-doc product sets a minimum ICR of 1.5 times. That means the accepted lease income must cover tested interest by the lender's required multiple. Another lender may use a different ICR, a DSCR or a different rent calculation, so ask what income is counted and what rate is used in the test. In Switchboard panel records, 1.25 times on net rent at the actual rate was the common non-bank standard.

What if there are several tenants?

The lender can look at the spread of lease expiries, tenant concentration and the weighted average lease expiry rather than relying on one expiry date. A property with five tenants is not automatically safer than one with a single tenant if most rent expires at the same time. See WALE and commercial loan terms.

What happens if the tenant leaves after settlement?

The finance risk changes because the income the lender relied on has changed. Vacancy does not automatically mean the loan is called in, but it can affect covenant compliance, refinance options and the next valuation. Read the loan agreement for review and covenant triggers, keep enough liquidity for vacancy and start the re-letting plan before the lease expires rather than after the rent stops.

Illustrative: 22 months remain on a shop leaseA buyer wants lease-doc finance on a shop with an unrelated tenant but only 22 months of firm term left. A product that ties the loan term to lease expiry may produce a very short facility or fail policy, while a different lender may assess the same property under another structure. Before exchange, ask whether renewal options count and whether a signed extension would materially change the loan. Illustrative only.

What income documents, ABN and GST history can a low doc lender ask for?

Expect the lender to ask for enough evidence to make your declared income credible, even when lodged tax returns are not the main test. Depending on product, that can include BAS, business trading statements, recent financial statements, an income declaration, current tax material and evidence of how long the business and borrowing entity have operated. The exact combination varies by lender.

ABN and GST history. The minimum trading and registration period is product-specific. GST registration itself is a tax rule, not a lending rule: business.gov.au states that most businesses must register once GST turnover reaches $75,000, while businesses below the threshold can generally choose to register. A lender can still require a longer GST history for its own credit policy. See current GST registration guidance.

Accountant's letters. Do not build the whole application around getting one until your accountant has agreed. CPA Australia's current guidance says the professional bodies' joint position is that accountant's letters requested to facilitate a financing arrangement should be declined because credit assessment is the lender's responsibility. The same guidance provides templates and recognises limited situations where an accountant may consider an engagement appropriate. Ask the lender whether BAS, trading statements or another document can satisfy policy instead. See CPA Australia's current accountant-letter guidance.

What if BAS, bank statements and declared income do not match?

The lender does not necessarily accept the highest number. It can compare the declared income with BAS turnover, business-bank deposits, management accounts, current liabilities and the business's ATO or GST position. One-off receipts, transfers between accounts, GST collected for the ATO and non-recurring revenue can all need explanation before the lender decides what income is usable.

Different lenders can calculate usable income differently. One lender may annualise a recent BAS or trading period, while another may want a longer period or another supporting source. If the evidence cannot reasonably support the declared figure, the lender can shade the usable income, request another document or move the application to a different documentation path. Ask how the serviceability income was derived before comparing two approvals.

Prepare before the application

  • Recent BAS and business bank statements
  • Latest lodged tax returns and notices, even if they lag current trading
  • Current ATO account position and any payment plan
  • Borrowing entity, ABN and GST registration dates
  • Contract, property details and lease if tenanted

Common avoidable stalls

  • BAS and deposits that do not reconcile
  • Assuming an accountant will sign a finance letter
  • A new entity with no explanation of the longer trading history behind it
  • Unexplained ATO arrears or missed payment-plan instalments
  • Submitting before the property and lease fit the chosen product
Illustrative: current trading is stronger than the last returnA self-employed borrower has a lodged return showing $180,000 of income, but recent BAS and business deposits show materially stronger current trading. An alt-doc lender may be able to assess the newer evidence rather than making the borrower wait for the next return, provided the evidence reconciles and the rest of the file fits policy. That is the use case for alt doc. It is not a way to invent income that the business cannot support.

What happens after you apply, after settlement, and is low doc actually faster?

Low doc is not automatically faster. It can reduce the time spent producing historical financials, but valuation, property due diligence, lease review, credit assessment and legal documents can still control the timetable. In Switchboard panel records, commercial property files commonly took about two to six weeks to formal approval, with faster and slower outliers depending on complexity and valuation timing. Treat that as an observed range, not a promise.

  1. Path selection. Match the evidence, property use and purpose to a lender before submission.
  2. Indicative terms. Check LVR, rate, fees, term and key conditions before paying for a valuation where possible.
  3. Valuation. The lender orders or accepts a valuation and confirms whether the security fits policy.
  4. Income or lease assessment. Alt doc evidence is reconciled; lease doc is tested against tenant, lease and cover requirements.
  5. Formal approval and documents. Conditions are cleared and your solicitor reviews the facility documents.
  6. Settlement. The lender funds its approved amount and you provide the balance, duty, fees and any GST required.

What if you already signed a contract with a finance date?

Give the broker and lender the finance date immediately. The biggest mistake is waiting for document collection to finish before ordering the valuation. If the deadline is at risk, speak to your solicitor about the contract before the date passes. Do not assume an indicative approval satisfies a finance clause.

What should you have ready before the first lender conversation?

  • Property address, purchase price or estimated value, and whether your own business or an external tenant occupies it.
  • Loan purpose: purchase, refinance, equity release or debt consolidation.
  • Required loan amount and the cash you can contribute without stripping the business of working capital.
  • Borrowing entity, ABN and GST history, current ATO position and latest financial evidence.
  • Lease, rent, expiry and tenant details for investment property.
  • Contract dates, including finance and settlement deadlines.

What happens after settlement?

Treat low doc as a finance path, not a permanent identity. Once lodged returns catch up with current trading, a full-doc refinance may open different lenders or pricing. Before refinancing, compare the remaining balance, current valuation, discharge and deferred facility fees, new establishment and legal costs, and any break costs. For lease-doc property, keep watching lease expiry, tenant performance and any ICR or review covenant in the facility agreement.

Do low doc commercial loans have annual reviews or revaluations?

Not all of them. Review policy is lender- and facility-specific rather than being determined by the words "low doc". Some current Australian commercial products expressly advertise no annual reviews, while other facilities can contain financial-information covenants, review dates, revaluation rights or shorter contractual terms. Read the letter of offer for those provisions instead of assuming the documentation path determines the review cycle. See a current commercial product example that advertises no annual reviews.

Does low doc cost more, and when should you refinance to full doc?

It can cost more, but the documentation label alone does not tell you the total cost. Price can change with LVR, property, evidence, loan size, interest-only use and lender. Current published commercial low-doc products also show that fees can include application, establishment, valuation, settlement, documentation, service, early-exit or deferred facility and discharge costs. Compare the facility over the period you expect to keep it, not just the headline rate.

A later full-doc refinance is worth testing when your lodged returns now support the debt, the property valuation gives you a workable LVR and the saving exceeds the cost of leaving the existing facility and establishing the new one. A refinance is not automatically better just because the new rate is lower.

Simple refinance break-even testIf changing lenders costs $12,000 all-in and saves $1,000 a month in interest and recurring fees, the simple break-even is about 12 months before allowing for tax, changing balances or other differences. If you expect to sell in six months, paying the refinance costs may not make sense. If you expect to hold for five years, the same numbers tell a different story. Illustrative only.

For current pricing context, see commercial property loan rates in 2026. For a specific offer, compare every fee in the term sheet and loan documents.

Are low doc commercial property loans regulated, and do the new DTI limits apply?

A genuine commercial-property loan for business purposes generally sits outside the consumer credit regime, and APRA's February 2026 DTI portfolio limits apply to residential mortgage lending by ADIs, not ordinary commercial-property lending. Purpose and borrower structure still matter, so do not use the property label alone to decide the legal treatment of a particular facility.

Section 5 of the National Credit Code, "Provision of credit to which this Code applies", reaches credit to a natural person or strata corporation provided wholly or predominantly for personal, domestic or household purposes, or to purchase, renovate or improve residential property for investment purposes. ASIC's guidance puts it the same way, and adds that loans to companies are not subject to the credit legislation (asic.gov.au, INFO 101, updated 20 October 2020). Commercial premises are not residential property.

From 1 February 2026, APRA limits each authorised deposit-taking institution to 20 per cent of its new residential mortgage lending at a debt-to-income ratio of six or more, applied separately to owner-occupier and investor lending (apra.gov.au, DTI activation notice). It is a limit on a share of a bank's residential lending, not a cap on any one borrower, and it does not reach commercial property loans.

Fewer rules also means fewer protections. ASIC notes that lenders that only provide commercial loans are not required to have a credit licence and are not legally required to be a member of AFCA, the free external complaints body (asic.gov.au, INFO 207). Check whether your lender is an AFCA member before you sign. In a lane with fewer statutory protections, a lower LVR, a proper serviceability assessment and your own due diligence do the protecting. For how commercial property lending is regulated more broadly, see the parent guide.

Which documentation path fits your situation?

Start with the situation, not the product label. The right path depends on whose income carries the debt, which evidence is current, what the property is used for and how much leverage you need.

Start with the situation that sounds like yours

Start with full doc.

If lodged returns already show the income, use them. Full doc usually opens the widest lender set and avoids paying for flexibility you do not need.

Indicative only

Test alt doc before waiting for another tax year.

Recent BAS, bank statements or other accepted evidence may show the stronger current position. Reconcile the evidence before submission and confirm the lender's ABN, GST, property and LVR rules.

Indicative only

Test lease doc and full-doc investment lending side by side.

An arm's-length lease can carry serviceability on some products. Compare ICR, term, tenant rules, LVR, fees and what happens as the lease approaches expiry.

Indicative only

Expect the business to carry the assessment.

A lease to your own entity is not automatically external income. Full doc or alt doc is usually the cleaner starting point for owner-occupied premises.

Indicative only

Compare the exit as carefully as the new approval.

For refinance or equity release, check current balance, conduct, valuation, purpose of funds, new LVR and all exit and establishment costs. If your returns have caught up, also test full doc.

Indicative only

Low doc can solve a real timing problem when

  • Your business is established but lodged returns lag current trading
  • You have alternative evidence that reconciles
  • The property and requested LVR fit specialist policy
  • Waiting for another tax year would cost a genuine opportunity

Low doc is the wrong shortcut when

  • Your current returns already support a better full-doc option
  • The income figure cannot be reconciled to the business records
  • The deposit only works if the valuation is optimistic
  • You are relying on a related-party lease as if it were independent rent
  • You have not allowed for duty, GST, fees and post-settlement working capital

The next question after product fit is usually property fit. See owner-occupied versus investment, warehouse and industrial property, mixed-use property, or talk to us about the actual commercial property loan.

Low doc commercial lending is a set of assessment paths, not one universal product ladder. If your lodged returns are current, full doc is usually the first path to test. If they lag current trading, alt doc can use more recent business evidence, but the BAS, bank statements and declared income still need to reconcile. If an unrelated tenant carries the property, lease doc may use the rent instead, with current published Australian products ranging materially in LVR and term. Before comparing rate, confirm whose income carries the loan, the property and valuation limits, cash to settle, review conditions, lease-expiry risk, total fees and the refinance exit.

Key takeaway: choose the evidence path that matches the real borrower and property situation, then compare LVR, term, total cost, review conditions and exit risk.

Frequently Asked Questions

Low doc commercial property loans use an alternative way to verify repayment capacity when traditional lodged financials are not the main evidence. Depending on the lender, that can mean BAS, business bank statements, other alternative documents, a declaration-based pathway or an arm's-length commercial lease. Low doc describes the evidence path, not the borrower's credit quality.

Full doc relies mainly on lodged tax returns and financial statements. Alt doc relies on lender-accepted alternative evidence that can better reflect current trading, such as BAS or business bank statements. Alt doc can be useful when an established business is performing better than its latest lodged return shows.

No. Low doc describes how income or repayment capacity is verified. Credit history, repayment conduct, ATO position, security and serviceability are assessed separately.

Yes on some current Australian products. Published examples reviewed on 30 September 2026 reach up to 80 per cent LVR on some full-doc, alt-doc and lease-income commercial loans. Other products cap lower, so the actual LVR depends on the lender, property, loan size, location, valuation, tenant and evidence.

Yes on some current Australian non-bank lease-income products. Other lease-doc products tie the term to lease expiry or cap it at five years, so lease doc does not have one universal maximum term.

Do not assume so. Some published lease-doc products require an arm's-length tenant and do not accept related-party rent under that pathway. If your own trading business occupies the premises, full doc or alt doc is usually the first path to test.

Yes, depending on lender policy. Current Australian low-doc and lease-doc products can include refinance, and some also allow equity release. Compare the new loan with the existing facility after allowing for discharge, deferred facility, valuation, legal and establishment costs.

Depending on the product, a lender can ask for BAS, business bank statements, recent financial statements, a signed income declaration, current tax material, ATO account information, entity and registration history, the property contract and the lease if the property is tenanted.

Not always. CPA Australia's current guidance says accountant's letters requested to facilitate financing should generally be declined because credit assessment is the lender's responsibility. Ask the lender whether BAS, bank statements or another accepted document can satisfy policy instead.

Not automatically. Less historical financial paperwork can reduce preparation time, but the valuation, property due diligence, lease review, credit assessment and legal documents can still control the timetable.

The lender can reduce its advance because the LVR is usually applied to the lower accepted value. The contract price does not automatically fall, so the borrower may need to contribute more cash or renegotiate the transaction if the contract allows.

Not all of them. Annual-review and revaluation policy depends on the lender and facility. Some current Australian commercial products expressly advertise no annual reviews, while other loan documents can include review dates, financial-information covenants or revaluation rights.

Often, unless the sale is GST-free as the supply of a going concern, which needs a GST-registered buyer, a written agreement and the enterprise supplied with the property, such as a tenanted building sold with its leases. If GST is payable, lenders commonly size the loan without it, so fund it at settlement and recover the credit through your BAS. See the cash you need on top of the deposit.
