Navigating the Serviceability Squeeze: How to Refinance in a Tough Lending Environment

Refinancing used to be relatively straightforward for borrowers with a clean repayment history and enough equity. In 2026, that is no longer the case for many households. Even borrowers who have been meeting repayments on time are finding they cannot move to a better deal because they do not pass current serviceability rules.

That is the serviceability squeeze: your existing loan may be manageable in real life, but a new lender still has to assess whether you can afford the debt under today’s stricter settings. If you are trying to use a mortgage serviceability calculator australia borrowers often search for, it helps to understand why the result may look harsher than expected.

This guide explains what has changed, who is most affected, and what practical steps may improve your chances of refinancing.

What has changed in the lending environment

Several current conditions are combining to make refinancing harder.

First, the Reserve Bank of Australia kept the cash rate on hold at 3.85% on 1 September 2026, citing persistent services inflation and signalling that rates may stay higher for longer. In plain terms, lenders are still assessing borrowers in a high-rate environment rather than planning around rapid relief.

Second, the 3% home loan serviceability buffer remains in place. That means lenders generally assess a refinance application at a rate materially above the actual loan rate being offered. Even if the rate you want is lower than your current one, the application may still fail the servicing test because the assessment rate is much higher.

Third, household leverage remains a real issue. APRA’s June 2026 Quarterly ADI Property Exposures data showed that 24.8% of new home loans were approved with a debt-to-income ratio of six or more. A high DTI does not automatically mean a loan is unsuitable, but it does tell you many borrowers are already carrying large debt relative to income.

Finally, refinancing activity itself has weakened. The latest ABS Lending Indicators reported a 5.2% fall in the value of new housing loan commitments, driven by a sharp drop in refinancing activity as more borrowers fail to qualify with other lenders.

Why this matters for refinancers

The practical effect is that more homeowners are becoming what the market often calls mortgage prisoners: borrowers who may be able to manage their current repayments, but cannot satisfy another lender’s servicing model.

That matters because staying put can be expensive. A Canstar report found the loyalty tax for variable rate customers has grown to an average of 0.65%, potentially costing homeowners thousands per year. At the same time, competition for strong refinance files remains real, with some major banks offering up to $2,500 in refinance cashback offers. The catch is that those offers usually only help borrowers who already clear the serviceability hurdle.

So the problem is not simply whether cheaper rates exist. It is whether you can qualify to access them.

Who is most affected by the serviceability squeeze

Not every borrower is affected equally. In our experience, the pressure is usually strongest for borrowers in one or more of these groups.

Borrowers coming off older fixed rates

A new wave of fixed-rate expiries has pushed many loans onto much higher variable rates. Some households can absorb the jump. Others can meet repayments, but only with tighter cash flow than before. That can make their position look weaker when another lender reviews bank statements, expenses and existing debts.

Households with high debt-to-income ratios

If your mortgage is large relative to your income, serviceability can become very tight even if your repayment history is perfect. The higher your overall debt load, the less room there is for a lender’s buffer and living expense assumptions.

Borrowers with multiple consumer debts

Car loans, personal loans, HECS-HELP obligations, tax debts and especially large credit card limits can all reduce borrowing capacity. Even if you rarely use a card, the approved limit is often what matters for assessment.

Self-employed borrowers

Business owners and contractors may have strong long-term income but still face extra scrutiny because income can be more complex to verify. If that sounds familiar, it may help to review options for self-employed home loans rather than approaching the refinance as a standard PAYG application.

Borrowers in slower-moving property markets

CoreLogic’s national Home Value Index rose only 0.2% in August 2026, the softest monthly result in 18 months, indicating affordability constraints are weighing on the market. If your property value has not moved much, or has softened in your pocket of the market, your usable equity may be tighter than expected.

Why your borrowing capacity may look lower than you expected

Many borrowers get a shock when they use a calculator or speak with a lender. Usually, the issue comes down to how serviceability is assessed rather than how you manage money day to day.

A lender may look at:

• your gross income and whether all of it is acceptable for servicing
• your existing mortgage repayments
• a higher assessment rate because of the 3% buffer
• declared and benchmark living expenses
• credit card limits, not just balances
• other debts such as car finance, personal loans or ATO liabilities
• number of dependants
• property type and loan purpose
• the amount of equity available after costs

That is why a basic online estimate is useful, but limited. A borrowing power calculator can provide a starting point, but the real test is how a specific lender interprets your income, liabilities and expenses.

Practical ways to improve serviceability before refinancing

If you are close to the line, small changes can make a material difference. The key is to focus on actions that lenders actually recognise in their assessment.

1. Reduce credit card and line-of-credit limits

This is one of the simplest and most effective steps. Lenders usually assess the full approved limit of a credit card, even if the balance is zero. If you have several cards or very high limits “just in case”, reducing or closing them may improve serviceability.

Important point: paying off a card is not always enough on its own. If the limit remains open, it can still affect the assessment.

2. Consolidate short-term debts carefully

Rolling unsecured debts into a home loan can reduce monthly commitments and improve cash flow, which may help serviceability in some scenarios. It can also simplify finances.

However, consolidation is not automatically the right move. Converting short-term debt into long-term secured debt can increase total interest paid over time if it is not managed properly. If you are exploring that path, review the structure carefully and compare it against your goals. Derwent’s Debt Consolidation page outlines the basics.

3. Clean up discretionary spending before applying

Lenders do not expect a perfect household budget, but they will review spending patterns. Large recurring subscriptions, frequent discretionary spending, gambling transactions or persistent overdrawing can weaken an application. A cleaner three- to six-month bank statement history can help present the file more clearly.

4. Pay down personal loans or car finance where possible

Installment debts can have an outsized effect on serviceability because they create fixed monthly commitments. Clearing a small car loan or personal loan may improve your borrowing position more than making the same payment directly off your mortgage.

5. Check whether your income evidence is up to date and complete

Many refinance applications run into trouble because income is poorly presented rather than because it is insufficient. That may include missing payslips, unclear overtime history, outdated tax returns, or business financials that do not tell the full story.

For self-employed borrowers especially, packaging income correctly can matter just as much as the headline numbers.

6. Avoid taking on new debt before your application

New finance for a car, furniture, solar, business equipment or buy-now-pay-later commitments can reduce capacity right before assessment. If refinancing is a priority, it often makes sense to stabilise your position first.

7. Consider whether a like-for-like refinance is more realistic than cash out

A simple refinance replacing the existing balance may be easier to justify than a refinance that also seeks extra funds. If your main goal is to reduce rate pressure, keeping the request straightforward may improve lender appetite. If you do need to access equity, start by understanding the trade-offs through Equity Release / Cash Out.

Opportunities borrowers should still consider

A tougher lending market does not mean there are no options.

Pricing pressure is still creating refinance opportunities

Banks and non-banks still want quality customers. That means pricing can be competitive for borrowers who fit policy, and some lenders continue to use cashback or rebate offers to attract refinancers. These should never be the main reason to refinance, but they can be a secondary benefit if the overall loan structure stacks up.

Some lender policies are more flexible than others

Not all lenders assess the same way. Income shading, treatment of overtime, acceptable rental income, approach to casual employment, and views on certain liabilities can vary from lender to lender. This is especially relevant for borrowers who miss one lender’s servicing model by a narrow margin.

Non-bank lenders may suit some scenarios

Non-bank lenders can be worth considering where major bank policy is too rigid. That does not mean easier lending in every case, and it does not remove the need to demonstrate affordability. But policy settings can differ enough to create a viable path for some borrowers.

The right fit depends on the full picture: rate, fees, flexibility, loan features, and whether the loan solves the borrower’s problem without creating a new one.

Risks to watch before you refinance

When borrowers feel trapped, it is easy to focus only on escaping the current rate. It is worth slowing down and checking the full refinance cost.

Consider:

• discharge fees from your current lender
• application, settlement or valuation fees with the new lender
• whether a lower rate comes with fewer features
• whether extending debt over a longer term increases total interest
• whether debt consolidation masks a spending issue rather than solving it
• whether a non-bank option suits your long-term plan
• whether fixed or variable structure matches your cash flow needs

A lower advertised rate is only one part of the decision. A proper Home Loan Review should look at pricing, policy fit and the likely long-term outcome.

What borrowers should do before speaking with a lender or broker

Preparation matters more in a tight servicing environment. Before making applications, it helps to gather a clear snapshot of your position.

Run the numbers honestly

Use a calculator as a rough guide, but be realistic about expenses, debts and dependants. If you want to test the effect of a lower rate on cash flow, a Refinance Savings Calculator can help frame the discussion.

List every current liability

Include:

• mortgage balance
• credit cards and limits
• personal loans
• car loans
• HECS-HELP
• tax debts
• buy-now-pay-later accounts
• guarantees or co-borrower exposures

Review your repayment history

Recent missed repayments, arrears, dishonours or overdrawn accounts can make a borderline application harder. If there have been temporary issues, be ready to explain them clearly.

Think about the goal of the refinance

Are you trying to:

• reduce your interest rate
• improve monthly cash flow
• consolidate debts
• restructure from fixed to variable
• remove a borrower
• access equity

The clearer the objective, the easier it is to identify the right lender pathway.

When speaking with a broker can help

A broker is most useful when your scenario sits outside a clean, vanilla refinance.

That includes borrowers who:

• have failed servicing with their current bank or another lender
• have high credit card limits or multiple debts
• are self-employed or have variable income
• need a debt consolidation strategy
• want to compare bank and non-bank policy options
• are unsure whether refinancing is realistic right now

In those cases, the value is often less about rate shopping and more about policy triage: working out whether the deal is currently possible, what is holding it back, and what changes may improve the outcome over the next few months.

If your main concern is whether you are stuck paying a loyalty tax on an uncompetitive variable rate, start with a structured review of the numbers and lender policy rather than sending multiple applications. You can explore the refinance process in more detail on Derwent’s Refinance Home Loans page.

The bottom line

Refinancing in 2026 is harder than many borrowers expect, even for people who have done everything right. Higher rates, the 3% serviceability buffer and stricter lender assessment models mean some homeowners are effectively locked into loans they would not choose today.

But being declined once does not always mean there is no path forward. In many cases, the answer is to improve the serviceability position first, simplify debts, reduce unused credit limits, present income more clearly, and target lenders whose policies better match the scenario.

The right strategy depends on your numbers, your property, and what you are trying to achieve from the refinance.

Frequently asked questions

Why can’t I refinance if I’ve never missed a mortgage repayment?

Because a new lender does not assess your loan purely on repayment history. They must apply their current serviceability rules, including higher assessment rates, living expense assumptions and treatment of other debts such as credit cards or car loans. You may be managing your current loan, but still fall short under a new lender’s model.

Will reducing my credit card balance improve serviceability?

Sometimes, but reducing the balance alone may not be enough. Many lenders assess the approved credit limit rather than the amount owing. Reducing or closing unused limits can have a bigger effect than simply paying down the card while keeping the same limit open.

Can debt consolidation help me refinance?

It can in some cases, particularly if it reduces monthly commitments and simplifies your liabilities. But it is not automatically the best option. Consolidating short-term debts into a home loan can increase the time over which the debt is repaid, so the structure needs to be assessed carefully.

Are non-bank lenders easier for refinancing?

Not necessarily easier, but their credit policies can differ from major banks. In some scenarios, that can make a meaningful difference for borrowers with complex income, tight serviceability or unusual liabilities. The trade-off should be assessed across rate, fees, flexibility and suitability.

Should I apply with multiple lenders to see who says yes?

Usually, no. Multiple applications in a short period can complicate matters, especially if your scenario is already tight. A better approach is to review your servicing position first, identify the main obstacles, and target lenders whose policy is more likely to suit your circumstances.

What this means for you

If you’re unsure whether you can refinance in the current market, a broker can help you understand where the pressure points are and whether there are realistic options to improve your position.
