With the RBA holding the cash rate at 4.35% and three of four major banks calling the peak, rate cuts are not expected until at least mid-2027. But when the RBA does start cutting, the refinancing window will open fast — and being prepared now could save you tens of thousands of dollars over the life of your loan.
Here is how to position yourself for a smart refinance in 2026-27, including what to do with your current loan, how APRA's 3% serviceability buffer affects refinancing, and which refinancing costs to factor in.
The Rate Environment: 4.35% and Holding
The cash rate has been held at 4.35% following three consecutive 25bp hikes in February, March, and May 2026. CBA, ANZ, and NAB forecast this as the peak. Westpac forecasts two more hikes to 4.85% by September 2026. The earliest rate cut currently projected by any major bank is mid-2027.
In this environment, most variable-rate owner-occupier loans sit between 6.2% and 6.5%. If you are paying more than 6.5%, you may be overpaying relative to what a refinance could deliver, even before rate cuts begin.
Why Refinance Now vs Waiting for Rate Cuts
Refinancing in a high-rate environment offers benefits that are independent of the cash rate direction:
Immediate rate reduction. Even at the current 4.35% cash rate, lender competition for quality borrowers persists. If your current rate is above 6.5%, a refinance to a lender offering 6.2% or lower saves you around $100-$150 per month per $400,000 of loan.
Cashback offers. Some lenders still offer cashback incentives of $2,000 to $4,000 for refinancing, covering most or all of the switching costs.
Loan restructuring. You can roll high-interest credit card debt, a car loan, or a personal loan into your mortgage at a lower rate, reducing your overall monthly outgoings. Caution: you are converting short-term debt into long-term debt secured against your home.
Fixed-rate expiry. If you fixed at 2% to 3% during 2021-2022, your fixed term may be expiring soon. Your loan will roll onto the lender's standard variable rate — often significantly higher than competitive variable rates. Refinancing immediately upon expiry avoids paying the lender's default rate.
Better features. Offset accounts, redraw facilities, split-loan options, and the ability to make unlimited extra repayments without penalty vary between lenders. Refinancing lets you pick a loan that matches how you manage your money.
The Serviceability Buffer Challenge
The biggest barrier to refinancing in 2026 is the APRA serviceability buffer. Since October 2021, all ADIs (authorised deposit-taking institutions) must assess new borrowers at 3% above the actual loan rate. With variable rates around 6.2% to 6.5%, lenders assess your capacity to repay at approximately 9.2% to 9.5%.
This means:
- Your income must demonstrate the ability to service the loan at roughly 9.5%
- Any decline in your income since you took out your original loan will make refinancing harder
- Rental income on investment properties is assessed at the same buffer
- Existing debts (credit cards, personal loans, car loans, HECS) reduce your assessed surplus at the elevated rate
How to Improve Your Serviceability Assessment
Close unused credit cards and reduce credit limits. Lenders assess cards based on the credit limit, not the balance. A $10,000 credit card limit can reduce your borrowing capacity by approximately $30,000 to $40,000 at a 9.5% assessment rate.
Consolidate small debts before applying. Pay off or consolidate personal loans, car loans, and other consumer debt. Even small monthly payments are magnified by the 3% buffer.
Document all income. Self-employed borrowers need clean financials — two years of tax returns and notice of assessments, BAS statements if applicable, and letter from your accountant. Any gaps or inconsistencies will either delay or derail a refinance application.
Reduce living expenses on paper. Lenders use either the Household Expenditure Measure (HEM) or your actual declared expenses, whichever is higher. Be accurate but avoid overstating discretionary spending.
When to Strike: The Refinancing Timeline
Now (mid-2026): Start preparing. Check your current rate. Request a discharge form quote from your existing lender. Calculate switching costs. Get your financials in order. Talk to a broker about which lenders are offering competitive rates for your loan profile.
Late 2026 (if Westpac is right about further hikes): Variable rates may push toward 7% for some borrowers. In this scenario, any lender offering under 6.5% is a target. Fixed rates may also start to offer value if markets price in future cuts.
Mid-2027 (if the majority forecast is right): The first RBA rate cut by mid-to-late 2027 would trigger a refinancing wave. Lenders will compete aggressively to win refinancing business as the market shifts. The borrowers who have already prepared — reduced debts, documented income, identified target lenders — will move fastest and capture the best deals before the wave fully crests.
Costs of Refinancing
Refinancing is not free. Factor these costs into your calculation:
- Discharge fee: $150 to $400 from your existing lender
- Government fees: Mortgage registration fee ($150-$200) and discharge of mortgage fee (varies by state)
- Break cost (fixed loans): If you are exiting a fixed-rate loan early, the break cost can be substantial in a rising or falling rate environment — get a quote from your lender before committing
- Application or establishment fee: $0 to $600, often waived by the new lender as a refinance incentive
- Valuation fee: Usually covered by the new lender
- LMI (if LVR is above 80%): If your loan-to-value ratio exceeds 80%, you may need to pay Lenders Mortgage Insurance again on the new loan unless your existing loan was LMI-free and you are not increasing borrowings
A typical refinance costs $500 to $1,500 in direct fees. If the rate saving exceeds this within 12 to 18 months, it is usually worthwhile.
Fixed vs Variable When Refinancing
With rates at or near their peak based on the majority forecast, fixing for 2 to 3 years could lock in a rate that looks attractive as variable rates eventually fall. But the risk is real: if Westpac is correct and rates rise further, locking in now at current fixed rates could be advantageous. If CBA, ANZ, and NAB are correct and rates plateau then fall from mid-2027, a variable rate may offer a better outcome over 2 to 3 years.
A split loan — half fixed, half variable — hedges both directions.
FAQ
Will I be assessed at 9.5% when I refinance? Yes, if the variable rate you are applying for is around 6.2% to 6.5%. APRA's 3% serviceability buffer means lenders assess at the higher of the loan rate plus 3% or their own floor rate. This is a key reason why some borrowers find they cannot refinance even to a lower rate — their income no longer meets the elevated assessment rate.
Can I refinance if my property value has dropped? Yes, but you may face a higher LVR. If your LVR exceeds 80%, you will likely need to pay LMI unless your existing loan qualifies for an LMI waiver. Some lenders offer LMI-free refinancing up to 85% LVR for specific professions (doctors, lawyers, accountants).
What is a discharge form and why do I need it? A discharge authority form is a document you sign to authorise your current lender to release the mortgage on your property. Your new lender needs this to register a new mortgage. Processing typically takes 10 to 15 business days.
Is there a best time of year to refinance? Lenders are most aggressive with offers at the start of the financial year, at the end of calendar quarters when loan targets are closing, and in the weeks following an RBA rate cut when borrower interest surges.
Do non-bank lenders have the same 3% buffer? No. Non-bank lenders are not regulated by APRA and can apply their own serviceability standards. Some assess at 1.5% to 2% above the loan rate instead of 3%, which can meaningfully improve borrowing capacity. However, non-bank rates are typically higher than major bank rates, so the trade-off matters.
