Why a Property Portfolio Can Fail Servicing at a New Lender
Property Lending
Portfolio refinance · Servicing assessment · Investment lending
A property portfolio that services comfortably where it sits can fail at the lender you want to move it to, even when your repayment history is clean and the advertised rate is lower. The new lender makes a fresh assessment of the portfolio and of you now: existing debts, interest-only terms, rent, current income, living expenses, equity and its own policy. This guide shows where the calculation changes, how to tell servicing from a valuation or policy problem, and what to do before another application.
Quick Answer
A property portfolio can fail servicing at a new lender because a refinance is a fresh credit assessment, not a transfer of the old approval. The incoming lender tests every existing loan at its own rate plus a 3 percentage point buffer, assesses interest-only loans as principal and interest over the shorter remaining term, counts rent only after a haircut of at least 20 per cent, checks each property's negative gearing eligibility, and re-tests your current income, living expenses and other commitments. At a bank, the moved debt also counts as new lending under APRA's debt-to-income limit.
A refinance can also fail on valuation or LVR, evidence or lender policy even when servicing works. Before applying elsewhere, ask your current lender to reprice, then have the whole portfolio assessed before any formal application.

Why can a portfolio that services now fail at a new lender?
A portfolio that services with your current lender can fail at a new one because the new lender is assessing the position today, not inheriting an old approval. Six portfolio-specific servicing levers commonly change at the move: the buffer added to existing debts, the lender's floor rate, the principal and interest treatment of interest-only loans, rental-income shading, negative-gearing treatment in servicing and, at a bank, the debt-to-income limit on new lending.
Those six are only the portfolio layer. The incoming lender also reassesses the borrower's current income, living expenses, credit limits, personal and business debts, guarantees and the evidence supporting them. That is why a refinance can fail even when every repayment has been made on time and the new advertised rate is lower. The table below isolates the six portfolio-specific levers; the checklist later in the guide covers the borrower-side inputs as well.

| What is re-tested | The published position | Source |
|---|---|---|
| The buffer on every loan | APRA's mortgage serviceability buffer is 3 percentage points, and APRA expects banks to apply it to existing debts as well as the new loan. | APRA media release, 28 May 2026; APG 223 |
| The floor rate | Each lender sets its own floor. The assessment uses whichever of the floor or the rate plus buffer its policy produces. | Lender policy; APG 223 |
| Interest-only loans | Assessed as principal and interest over the term that remains after the interest-only period ends. | APG 223 |
| Rental income | A minimum haircut of 20 per cent in APRA's view, so no more than 80 per cent is counted, and less where vacancy risk is higher. | APG 223 |
| High debt-to-income lending | From 1 February 2026 each bank may fund up to 20 per cent of new investment loans, and separately 20 per cent of new owner-occupied loans, at a debt-to-income ratio of 6 times or more. | APRA letter to banks, 27 November 2025; unchanged 28 May 2026 |
| Negative gearing in servicing | Most major lenders stopped counting the negative gearing benefit for properties that no longer qualify between May and June 2026. Properties held before 7:30pm AEST 12 May 2026 generally still qualify, so lenders now ask for each property's acquisition date. | ATO, last updated 29 June 2026; Broker Daily, 30 June 2026 |

How does a new lender assess the loans you already hold with other lenders?
A new lender assesses every loan you hold, including loans with other lenders, at its own assessment rate rather than at the repayment you actually make. APRA expects banks to fully apply buffers and floor rates to both a borrower's new and existing debt commitments, so the whole portfolio is re-priced upward inside one calculator before a single new dollar is considered.
The buffer is published. On 28 May 2026 APRA confirmed that the mortgage serviceability buffer will remain at 3 percentage points. That is an addition to the rate used in the assessment, not a rate you will be charged, and each lender still sets its own floor rate and policy on top of it.
Interest-only loans are where the re-pricing bites hardest. APRA expects lenders to assess the ability to meet future repayments on a principal and interest basis over the term to which those repayments apply, excluding the interest-only period. Most of the damage comes from that principal and interest basis at a buffered rate. The shorter remaining term then adds to it, on every interest-only loan in the group. The illustration below shows the size of each step on one loan. How the incoming lender sees the group as a whole is covered in how lenders aggregate an investor's holdings, and the treatment of existing investment debt in a low-document file in one doc home loans with investment property debt.

| Basis | Monthly repayment | What changed |
|---|---|---|
| What you actually pay: interest only at an assumed 6.00% | $3,000 | Starting point. |
| Assessed principal and interest at 9.00% over 30 years | $4,828 | The 3 percentage point buffer and the principal and interest basis add $1,828 a month. |
| Assessed at 9.00% over 27 years (3 years interest-only left) | $4,939 | The shorter remaining term adds a further $111 a month. |
| Assessed at 9.00% over 25 years (5 years interest-only left) | $5,035 | The shorter remaining term adds a further $207 a month. |
Illustrative arithmetic only, using an assumed 6.00% rate plus the 3 percentage point buffer and standard monthly amortisation. It is not a rate, a quote or a lender's actual calculation. A lender whose floor rate is higher than 9.00% would assess at the floor, and each lender's policy differs.

| What is assessed | At your current lender | At the new lender | Why it changes |
|---|---|---|---|
| The loan being refinanced | Already approved, and repaid on the terms it was written on. | Assessed from scratch as new lending, at the new lender's own buffered rate. | The new lender makes its own approval. Your repayment history is evidence it may weigh, not a result it must adopt. |
| Loans held with other lenders | Each held on its own terms by whoever holds it. | Every one re-priced upward inside one calculator, at the new lender's buffer and floor. | APRA expects banks to apply buffers and floor rates to both new and existing debt, so nothing is taken at the rate you actually pay. |
| An interest-only period part way through | Costing you interest only, for the rest of the interest-only term. | Assessed as principal and interest over the term remaining after the interest-only period ends. | The principal and interest basis at a buffered rate lifts the assessed repayment most, and the shorter term adds to it. |
| The rate used in the assessment | Whatever the assessment rate was on the day each loan was approved. | The new lender's current floor rate or its current rate plus the buffer, as its policy sets. | An assessment made years ago is not re-run, it is replaced. |
| Rental income already being received | Established, banked, and evidenced by leases and statements. | Counted after the new lender's haircut, and only to the extent its policy accepts the evidence. | APRA's view is a minimum haircut of 20 per cent, with more where vacancy risk is higher. |

Both read 23 September 2026. A practice guide does not itself create enforceable requirements, and nothing above is a commitment any lender has made to you.
How much of your existing rent will the incoming lender count?
An incoming lender will not count all of your existing rent. APRA's view is that prudent serviceability policies apply a minimum haircut of 20 per cent to expected rental income, with larger haircuts where the risk of vacancy is higher, so a lender following that view counts no more than 80 per cent of it. That is a floor on the haircut, not a cap, and no lender is obliged to stop at 20 per cent.
The part that favours an established portfolio is evidence. APRA expects lenders would normally place less reliance on third-party estimates of future rent than on actual rental receipts. A buyer has an appraisal. You have leases, a tenancy history and banked receipts on every property you are moving. That does not change the haircut, but it removes any argument about whether the income exists. How a haircut is applied is set out in the rental income shading formula, and how rent is presented in a low-document portfolio file in one doc home loans and rental portfolio income.
The tax treatment of what you already hold is changing too. The negative gearing and capital gains tax reforms announced in the 2026 to 2027 Budget are now law and apply from 1 July 2027. Established properties held at 7:30pm AEST on 12 May 2026 are exempt from the negative gearing change, and the capital gains change applies only to gains that accrue after 1 July 2027. The restructuring guide carries the detail, and your own position is a question for a registered tax adviser.
Lenders have already acted on it. Between 18 May and 29 June 2026 most major banks and a number of non-bank lenders reprogrammed their servicing calculators so that the negative gearing benefit is only counted for properties that still qualify. Trade press reporting of those announcements says refinances of properties acquired before 12 May 2026 generally keep the benefit in servicing, while established properties bought after that date do not, and at least one major bank now asks brokers to test whether the loan services without the benefit before applying it. For a refinance, that means the new lender asks for each property's acquisition date, and a portfolio that mixes pre-May and post-May purchases services on a different number from the one it used to. Each lender applies its own eligibility rules, so ask how it treats your specific holdings before you lodge. The investor decision after the May Budget and commercial against residential investment property after the Budget sit alongside it.

Do debt-to-income limits apply when you move an existing portfolio?
Yes, when you move it to a bank. From 1 February 2026 APRA allows each bank to fund up to 20 per cent of its new investment loans, and separately up to 20 per cent of its new owner-occupied loans, at a debt-to-income ratio of 6 times or more. The limit covers new loans funded, and APRA's reporting standard counts externally refinanced loans inside new loans funded. So a loan refinanced to a new bank is inside that bank's limit, while a loan that stays as it is sits outside it. APRA's reporting guidance also counts an internal refinance where a new application or new credit assessment is made, so a re-assessed loan at your own bank can count too.
Three details change how this plays out for an investor. First, the limit applies to all authorised deposit-taking institutions, meaning banks, credit unions and building societies, and not to non-bank lenders, which set their own policy. Second, the investor share is measured separately from the owner-occupier share, and APRA said high debt-to-income lending had started to pick up, driven by loans to investors. Third, the limit is not binding across the system. In the June 2026 quarter, 8.9 per cent of new investment loans and 3.7 per cent of new owner-occupied loans were at a debt-to-income ratio of 6 times or more, against a limit of 20 per cent. An individual bank can still sit closer to its own limit, and because the limit is measured quarterly at the largest banks and on a four-quarter rolling basis at smaller ones, its appetite for a high debt-to-income file can change between periods. The purchase-side version of the same limit is covered in buying multiple investment properties, and the term itself in the debt-to-income ratio glossary entry.

| Situation | Inside the limit? | What it means for you |
|---|---|---|
| Staying with your current lender | No, while the loan is not replaced or re-assessed. | A repricing keeps the debt outside the limit. An internal refinance with a new credit assessment can count as new lending. |
| Refinancing to a new bank | Yes. APRA's reporting standard counts external refinances as new loans funded. | The move itself brings the debt inside that bank's 20 per cent share of high debt-to-income lending. |
| Refinancing to a non-bank lender | No. The limit applies to authorised deposit-taking institutions. | The lender's own policy decides. Compare the total cost, not only whether the file services. |
| Finance to build or buy a newly erected dwelling | Exempt, for banks that report those loans separately. | Relevant if a restructure moves the portfolio toward new builds, which also keep negative gearing from 1 July 2027. |
| The period the application lands in | Measured quarterly at the largest banks, four-quarter rolling at others. | Not binding in aggregate in the June 2026 quarter, but one bank's appetite can still change between periods. |

Is there a lower buffer or an APRA exception for refinancing?
No. There is no published prudential rule that gives a refinancing borrower a lower serviceability buffer. APRA does describe exceptions to policy, meaning loans a bank approves that do not meet its own standard criteria, and it says a refinancing borrower's past repayment behaviour can be taken into account. It names no reduced buffer, sets no percentage entitlement and creates nothing you can apply for by name.
What APRA published, in a letter to banks dated 9 June 2023, is a definition and a set of governance expectations. An exception is approved case by case, inside a bank's own risk appetite, and reported to its board. A broker cannot promise one and an applicant cannot request one. When a lender does look past its standard test, it is looking at evidence, most often a long clean repayment record on the very debt being refinanced. That same evidence matters when you stay put, which is why the single-loan version of this question is worth reading beside this one.
Where consumer credit law applies, which includes most loans to individuals for residential investment property, a lender or broker must assess whether the credit contract is not unsuitable for you. That is an assessment of your position against that lender's inquiries, not a score you carry between lenders, and nothing obliges the next lender to reach the same answer as the last. The serviceability glossary entry sets out the base terms, and property finance for self-employed investors covers how the file is usually put together.

What usually sends investors looking to refinance, and what should you do first?
Most investors reach this page after one of eight triggers: a rate that looks high against new-customer offers, an interest-only period ending, a fixed rate ending, wanting equity for another purchase or the business, a refinance decline, a softer income year, higher household expenses, or a valuation that leaves less usable equity than expected. Those triggers do not all have the same answer.
The first job is to identify the gate before you apply. A lower rate does not fix a serviceability shortfall, more income does not fix an unacceptable LVR, and a different lender does not fix missing evidence. A simple repricing request to the lender already holding the debt will often avoid a new full application, but any change to the facility can still trigger that lender's own assessment process.
Scroll the table sideways to see every column.
| What started it | What tends to happen next | The first move worth making |
|---|---|---|
| Your rate looks high against new-customer offers | You apply to a cheaper lender, and every loan in the group is re-tested. | Ask your current lender to reprice first. Moneysmart's first step before switching is to tell your lender you plan to move, because it may cut your rate to keep you. |
| An interest-only period is ending | The repayment steps up to principal and interest, and the instinct is to refinance for a fresh interest-only period. | Work out the principal and interest repayment you will face anyway, and ask your current lender what an extension would need, before assuming a move is the answer. |
| A fixed rate is about to end | The loan rolls to a variable rate, often not the lender's sharpest one. | Compare at expiry. Moving inside the fixed term can mean a break fee. |
| You want equity for the next purchase or the business | The new lender tests the whole group, including business debts you guarantee. | Consider releasing equity against one property, sized to what one lender's policy can carry, rather than moving everything. |
| You have already been declined | A second application goes in with the same file and another enquiry lands on your credit file. | Ask for the written assessment first, so you know whether it failed on commitments, income evidence or appetite. |
| The business had a softer year | The latest tax return can lower the income a full-document lender will use. | Check which income evidence the target lender will use and whether timing or a low-document route is relevant before you lodge. |
| Your income is similar, but household costs are higher | The new lender assesses your current living expenses and commitments, not the budget from the year the original loans were approved. | Map the lender-visible budget before rate shopping. If the shortfall is in expenses or limits, another application with the same numbers will not solve it. |
| You have equity, but the new valuation is lower than expected | The refinance can fail on security or become uneconomic because the LVR is too high, even if the servicing calculation works. | Work out the likely LVR and release requirement before treating the problem as serviceability. |

The portfolio-specific sequences in the other rows are Switchboard's practitioner observations from refinances we have placed, as at September 2026, not published lender rules. If you are weighing the move itself, see when a self-employed refinance is actually worth doing, and after a decline, whether a broker can help after the bank said no.
What should you check before you apply to a new lender?
Before you apply to a new lender, check eleven things: whether your current lender will reprice, the cost of leaving, your current income and living expenses, every other commitment, each interest-only expiry, rental evidence, property acquisition dates, which tax year will be used, the likely valuation and LVR, how many lenders will run a credit check, and, if you have already been declined, which gate failed. This separates a pricing problem from a serviceability, security, evidence or policy problem before another enquiry is recorded.
Before you apply anywhere
- Ask your current lender for a better rate, in writing. A simple retention or repricing request will often avoid a new full application because the existing loan is not being replaced, although the lender's process can vary.
- Get a payout figure for every loan and a break quote for any fixed loan. Moneysmart lists break fees, discharge fees, application fees, switching fees and lender's mortgage insurance as costs of switching.
- Write down the income and living expenses the new lender will assess today. Do not assume the budget from the last approval still works. For a self-employed borrower, identify which tax year, BAS period or alternative evidence the target lender will use.
- List every commitment the new lender will see. Include home and investment loans, business loans and guarantees, equipment finance, overdrafts, credit card limits and any ATO payment arrangement.
- Write down the interest-only expiry date on every loan. The less interest-only time left, the shorter the amortising term used in the assessment of that loan.
- Collect current leases and recent rent statements for every property. APRA says lenders would normally place less reliance on third-party estimates of future rent than on actual rental receipts.
- Record the contract date for every property. Negative-gearing treatment in servicing now depends on whether the property remains eligible under the 2026 tax reforms and on the lender's own calculator rules.
- Check which tax year the lender will use. A stronger or weaker year about to be lodged can change the income in the calculator, so timing matters before an application, not after it.
- Estimate the valuation and LVR on each property before you move anything. Enough servicing does not fix an LVR or security problem, and enough equity does not fix serviceability. Treat them as separate gates.
- Have the portfolio assessed across several lenders' policies before any formal application. Each formal application can add an enquiry to your credit file, so avoid sending the same unchanged file lender by lender. See how many credit enquiries is too many.
- If you have already been declined, identify the failed gate before applying again. Serviceability, security or LVR, evidence and lender policy have different fixes. Where consumer credit law applies and an assessment was made, ask what written assessment or explanation is available rather than guessing.
Moneysmart supports the switching-cost and existing-lender steps; APRA supports the servicing treatment of existing debts, interest-only loans and rental income; the Federal tax law supports the grandfathering date; and ASIC sets out responsible-lending assessment and disclosure obligations where the consumer credit law applies. The sequencing and portfolio-file points are Switchboard's practitioner observations, as at September 2026. General information only.
If the serviceability calculator says no, what should be audited before you apply?
A failed serviceability result should be treated as a diagnosis to check before it becomes another application. Confirm that the target lender's calculator contains the right existing-loan balances or limits, remaining terms, repayment types, credit limits, HECS or HELP debt, business debts and guarantees, ownership shares, rental income, living expenses and proposed loan structure.
Scroll the table sideways to see every column.
| Input to audit | What to check | Why it can change the result |
|---|---|---|
| Existing mortgages | Balance or limit, current rate, remaining term, repayment type and whether a loan being refinanced has also been left in an existing-liability field. | A lender can assess existing debt differently from the repayment leaving your bank account, and a wrong remaining term or duplicated liability can distort the result. |
| Interest-only loans | Interest-only expiry date and the principal-and-interest term remaining afterwards. | A short amortising term can produce a much higher assessed repayment than the current interest-only payment. |
| Credit cards and other limits | Current limits, proposed reductions or closures, lines of credit, car or equipment finance and overdrafts. | Some lender calculators assess a limit or a policy repayment rather than the balance you happen to owe today. |
| HECS or HELP and other commitments | That the debt has been entered in the field and method required by the target lender, together with any guarantees or business commitments that policy requires. | These commitments can reduce surplus even when they are not property loans. |
| Rental income | Ownership share, verified rent, property type and the target lender's shading. | Rental income is not necessarily counted dollar for dollar, and the accepted percentage can differ by lender and property type. |
| Income, expenses and dependants | Current accepted income, self-employed evidence, living-expense categories and the household profile used by the calculator. | The refinance is assessed on the position now, not the income and budget used when the existing loans were approved. |
| Security and proposed loan | Property value, postcode or security category, LVR, loan purpose, loan term and requested repayment structure. | A calculator can combine serviceability and security rules, so a result that looks like an income problem may actually be a policy or security constraint. |
Lender calculators differ in how they take these inputs: some use credit report data for liability balances, limits and remaining terms, and each sets its own method for HECS or HELP, credit cards and rental income. Switchboard practitioner observation from files we have placed, as at September 2026, not a rule that every lender follows.
What changes if you are self-employed and your latest financial year is weaker?
A weaker latest financial year can change refinance serviceability because lenders do not all verify self-employed income the same way. Published application requirements differ: some lenders assess most self-employed applicants on one financial year's tax returns, others ask for two years of returns or financial statements, and some also ask for BAS or business transaction statements where business performance is expected to fall. The same portfolio can therefore be assessed on different income at different lenders.
That does not make one lender automatically easier. It means a self-employed investor should confirm the exact document set, recency rules and income calculation the target lender will use before lodging. A newly lodged return can change the evidence available to the lender, particularly after a softer year, but tax reporting should be accurate and driven by tax obligations, never shaped for a loan application. Where full financials do not suit the file, the one doc home loan page covers the low-document route.
Based on published home loan application and policy material from several lenders, read 23 September 2026, and Switchboard practitioner observation as at September 2026. Documentation and assessment rules are lender-specific and change.
What are your options when the portfolio does not service at the new lender?
If a property portfolio refinance does not work, do not assume the answer is simply another lender. First identify whether the failed gate was serviceability, security or LVR, evidence, or lender policy. Only the first of those is a pure borrowing-capacity problem, and sending the same file elsewhere before you know the difference can create another enquiry without changing the outcome.
Where consumer credit law applies, lenders and brokers have responsible-lending assessment obligations. If an assessment was made, ask what written assessment or explanation is available so you can distinguish a file that failed on assessed commitments from one that failed on evidence or appetite.

Scroll the table sideways to see every column.
| Gate | What it looks like | What changes the answer |
|---|---|---|
| Serviceability | The lender's assessed repayments and other commitments are too high for the income it accepts. | Different policy, stronger acceptable income evidence, lower commitments, a different repayment structure, moving only part of the portfolio, or waiting for the file to change. |
| Security or LVR | The valuation, usable equity or security structure does not support the loan requested. | A different loan size, more equity, another security arrangement, a partial discharge or a later valuation. If only one property values poorly, moving a stronger standalone security may still be possible; if securities are crossed, the outgoing lender's release position also matters. A better servicing result does not solve this gate. |
| Evidence | The income, rent, liabilities, tax position or loan purpose cannot be evidenced in the way the lender requires. | Supplying the missing documents, choosing a policy that accepts the evidence you genuinely have, or waiting until better evidence exists. |
| Policy or appetite | The numbers may work, but the lender does not want that borrower, property, structure or concentration under its current rules. | A lender whose policy fits the actual risk, a simpler structure, or changing the transaction. Re-lodging the same file with the same policy problem usually changes nothing. |
Then weigh what moving costs against what it buys. Moneysmart notes that with less than 20 per cent equity you might have to pay lender's mortgage insurance on the new loan, and that you can ask for a refund of some of the insurance on your current loan. You might pay it, and you can ask, which is not the same as receiving a refund. On a multi-property move that cost can land more than once.
Source: Moneysmart, Switching home loans, read 23 September 2026. Whether lender's mortgage insurance, a refund or any switching cost applies depends on your equity position and on both lenders.
A non-bank lender is a real route for this kind of file, not a last resort. APRA's debt-to-income limit applies to authorised deposit-taking institutions, and its serviceability guidance is addressed to them, so a non-bank lender sets its own servicing policy. That policy may treat rental income, self-employed income or a multi-lender portfolio differently from a bank, and its pricing and terms reflect its own funding. Compare the total cost over the time you expect to hold the loan, not just whether it services.
The rest is structural. Releasing one property from a crossed mortgage has its own mechanics and timing, set out in getting off cross-collateralisation and the cross-collateralisation glossary entry. The order and cost of a wider restructure belong in the restructuring guide, and the evidence limits on releasing equity in the evidence limits on a cash-out refinance. If you want the lending options set against your own position, the property lending hub is the place to start, the one doc home loan page covers the low-document route for self-employed borrowers, and equity release and refinance covers releasing equity you already hold.
What can move the assessment
- Finding out which limb failed, by asking for the written assessment rather than guessing.
- Repricing with the lender that already holds the debt, where the lender can do so without replacing the loan or requiring a new full assessment.
- Better evidence on income that already exists, particularly leases and banked receipts on every property.
- Moving part of the property portfolio, sized to what one lender's policy can carry.
- Changing the repayment structure on loans whose interest-only period is shortening the assessment term.
- Choosing when to lodge, where a bank's appetite is measured over a period.
- A non-bank lender whose own servicing policy fits the file, priced on total cost.
What usually does not
- Asking for the buffer to be waived. There is no published rule creating a lower buffer for a refinance.
- Treating a long clean repayment record as if it decides the outcome. It is evidence a lender may weigh.
- Assuming the next lender inherits the last lender's assessment. It makes its own.
- Assuming rent already being received is counted in full. A haircut of at least 20 per cent applies.
- Trusting an online calculator fed with the repayments you actually make.
- Sending the same unchanged file to a second lender straight after a decline.
From our broking, indicative
What we see on property portfolio refinances we have placed, as at September 2026. Qualitative only, because a reader usually arrives here after something has failed or is expected to, and a figure in that position reads as a promise.
- Titles, statements and tax material come in quickly. Current leases for every property come slowly, and the loan contract for the one facility nobody has looked at since it was written comes last of all.
- Where several properties secure the same facilities, the part that generates the most back and forth is not the credit assessment. It is the discharge: which security is released, in what order, with whose consent, and what the arrangement looks like afterwards.
- The assumption borrowers most often carry over from their last application is that the assessment travels with them. The second most common is that interest-only periods are neutral because the repayment has not changed.
Indicative only, based on property portfolio refinances Switchboard has placed, as at September 2026. This is not a quote, not an offer, and not an indication of approval. Actual terms and outcomes depend on lender policy, the evidence on the file and your circumstances at the time of application. Not financial advice.
A property portfolio that services where it sits can fail at the next lender because the refinance is assessed against today's borrower, today's property values and the new lender's current policy. On the portfolio side, the new lender tests existing loans at its own buffer of 3 percentage points or its floor rate, assesses interest-only loans as principal and interest over the remaining term, counts rent after a haircut of at least 20 per cent, checks each property's negative gearing eligibility by acquisition date and, at a bank, treats the moved debt as new lending under the debt-to-income limit. On the borrower side, it re-tests current income, living expenses and every other commitment. A refinance can also fail on valuation or LVR, evidence or policy even when servicing works. Before you apply, ask your current lender to reprice, cost the exit, map every commitment and acquisition date, estimate each property's LVR and have the full portfolio assessed before another formal application. The property lending hub carries the lending detail once the failed gate is clear.
Key takeaway: a portfolio refinance is new lending, so the buffer, floor rate, interest-only term, rent haircut, negative gearing eligibility and, at a bank, the debt-to-income limit are all re-applied, alongside your current income and expenses. Work out which gate you need to pass, serviceability, security or LVR, evidence or lender policy, before you apply, and ask your current lender to reprice first.Frequently asked questions
It is harder than refinancing an owner-occupied home, and harder again when several investment properties move together. The incoming lender treats the move as new lending, re-prices every existing loan at its own buffered rate, and counts rent only after a haircut. A single investment property is usually manageable; a whole property portfolio is where the arithmetic turns. Whether the move is worth making at all is the question worth settling first.
A clean repayment history helps as evidence, but it does not make the new lender inherit the old approval. The incoming lender assesses your current income, expenses, other commitments and the whole portfolio under its current policy. A file can therefore have perfect conduct and still fail serviceability, security, evidence or policy. Whether the move is worth making at all is the question to settle before another application.
Yes. Moneysmart recommends asking your current lender for a better deal before switching because it may reduce your rate to keep your business. For a portfolio that would struggle under a fresh assessment, a simple repricing can sometimes deliver the objective without replacing the loans, although the lender's process can vary. Compare the offer with the full cost and benefit of moving.
Yes. A cheaper advertised rate can still fail serviceability because the lender does not decide the file by comparing the old repayment with the new one. It stress-tests the debts under its own assessment settings and reassesses current income, rent, expenses and commitments. The price you would pay if approved and the serviceability test used to approve you are separate calculations.
Yes. Your credit file records credit accounts and enquiries, your statements and tax material disclose the rest, and the incoming lender asks for every commitment directly, including business loans and guarantees. It then re-prices those loans at its own assessed rate rather than at the repayment you make. How a lender aggregates an investor's holdings covers what that looks like across several properties and several lenders.
No. APRA expects banks to apply their buffer and floor rate to a borrower's existing debt as well as the new loan, so every external loan is assessed at a buffered rate, and interest-only loans as principal and interest. This is the largest gap between what a property portfolio costs you and what it is assessed as costing. One doc home loans with investment property debt covers how that plays out on a low-document file.
Yes, they can reduce serviceability because the incoming lender assesses the commitments attached to you as well as the mortgages attached to the properties. Business loans, guarantees, equipment finance, overdrafts, personal debts and credit limits can all matter under lender policy. How a lender aggregates an investor's holdings covers the portfolio side of that calculation.
Yes. A like-for-like balance does not freeze the borrower assessment. The new lender assesses the financial position that exists when you apply, including the income evidence it accepts, current living expenses and other commitments, as well as the repayments it calculates on the existing portfolio. That is why a refinance can fail even when the debt amount has not increased.
They are assessed as principal and interest over the term that remains after the interest-only period ends, not over the original loan term. On one illustrative $600,000 loan, the move from an actual interest-only repayment to an assessed principal and interest repayment at a buffered rate adds about $1,800 a month, and the shorter remaining term adds roughly $110 to $210 more. Repeated across several loans, that is usually where the numbers stop working. The borrowing hierarchy explains where that leaves a given file.
No. When an interest-only period ends, the loan normally moves to principal and interest under its existing terms unless another arrangement is approved. A fresh serviceability assessment can arise when you ask to extend interest-only or materially change the loan. Work out the principal and interest repayment you will face and ask the current lender what options exist before assuming a refinance is required.
Less than all of it. APRA's view is that prudent policies apply a minimum haircut of 20 per cent to expected rental income, with larger haircuts where the risk of vacancy is higher, so a lender following that view counts no more than 80 per cent. Actual leases and rent receipts carry more weight than a third-party estimate. The rental income shading formula sets out how the haircut is applied.
Usually, for properties you held before 7:30pm AEST on 12 May 2026. Between May and June 2026 most major lenders changed their servicing calculators so the negative gearing benefit is only counted where a property still qualifies under the reforms that apply from 1 July 2027, and refinances of properties acquired before 12 May 2026 have generally remained eligible. Expect the new lender to ask for each property's contract date, and check with a registered tax adviser how the rules apply to you.
At a bank, yes. From 1 February 2026 APRA allows each bank to fund up to 20 per cent of new investment loans, and separately up to 20 per cent of new owner-occupied loans, at a debt-to-income ratio of 6 times or more. APRA's reporting standard counts an external refinance as a new loan funded, so a portfolio moved to a new bank is inside that bank's limit, while a loan that is only repriced stays outside it. In the June 2026 quarter the system-wide investor share was 8.9 per cent, well below the limit, and the limit does not apply to non-bank lenders. Equity release and refinance covers what else changes when a facility is rewritten.
No published APRA rule gives a refinancing borrower an automatic reduced serviceability buffer. APRA allows banks to use limited exceptions to their own lending policies where managed prudently, and past repayment behaviour can be relevant evidence, but an exception is case by case and is not an entitlement or product an applicant can demand. The serviceability glossary entry sets out what is being tested.
Yes. A refinance can pass serviceability and still fail on security or LVR if the new valuation does not support the loan size or release you need. The reverse is also true: strong equity does not make a servicing shortfall disappear. Treat valuation and serviceability as separate gates, and see the cash-out refinance evidence limits where the move includes equity release.
A non-bank lender can assess the portfolio differently because APRA's current DTI limit and residential-mortgage practice guidance are directed to authorised deposit-taking institutions. A non-bank therefore sets its own servicing policy, which may treat rent, self-employed income or portfolio debts differently. Compare the total cost and structure, not just whether one calculator produces a pass.
When a credit provider accesses your consumer credit report in connection with an application, the OAIC says that information request is recorded as a credit enquiry and can include the type and amount of credit sought. Not every early policy or servicing check necessarily involves that step, because the process varies. Before another formal application, ask whether a credit report will be accessed and whether anything in the file has changed since the last decline. See what appears on an Australian credit report.
It can, in both directions. A move resets the assessment against the new lender's policy, which may be more or less generous than the one you left, and at a bank it places the debt inside that bank's new-lending measures. Each formal application is also recorded on your credit file. Buying multiple investment properties covers the purchase-side version of the same constraint.
Often yes. Moving only part of a property portfolio can be useful when the whole group will not fit one lender's serviceability or policy, but it depends on how the loans and securities are arranged. Where properties are cross-collateralised, releasing one can require a discharge and new security position. See getting off cross-collateralisation and the portfolio restructuring guide.
