Refinance Home Loan Australia

Home loan refinancing replaces your current residential mortgage with a new home loan, either with your existing lender or a different one. Australians refinance to get a better rate, reduce repayments, switch lenders, access home equity, consolidate debt, change loan features or move from fixed to variable — after checking all costs and confirming eligibility at the new lender's assessed rate.

Refinancing is worth it when total savings outweigh all switching costs over a realistic period. Most borrowers break even on switching costs within 12 to 24 months when moving to a meaningfully sharper rate. It is not worth it if fixed rate break costs are high, if LMI applies again at the new lender, if you are selling soon, or if the comparison rate difference is small after fees. Always check the comparison rate, not just the headline rate.

Consider refinancing if your current rate is materially above what new customers are being offered. In 2026, competitive owner-occupier variable refinance rates start from the low-to-mid 5s. If your rate is noticeably higher and you have equity above 20%, a rate review is worth doing. Common triggers are loyalty-tax pricing, fixed rate expiry, wanting equity access, consolidating debt or switching to a lender with better features. The surge in refinancing activity in 2026 is being driven by both rate certainty-seeking and cost-of-living debt consolidation.

Refinancing involves reviewing your current loan, comparing new options, checking equity and serviceability, submitting documents, completing a lender valuation, receiving approval and settling. At settlement the new lender pays out the old lender and your old mortgage is discharged. Banks assess serviceability at 3% above the offered rate — confirm you qualify at that assessed rate before formally applying anywhere.

Refinance costs typically include discharge fees from your current lender (commonly $150 to $400), government mortgage registration fees (varies by state), valuation fees, application or settlement fees and fixed rate break costs if exiting a fixed loan early. Some lenders offer cashback incentives of up to $3,000 to offset switching costs. Calculate all costs before deciding — a $3,000 cashback on a less competitive rate can still cost more over time.

APRA requires banks to assess home loan applications — including refinances — at 3 percentage points above the offered rate. This is the mortgage serviceability buffer. If a lender offers 6%, you are assessed at 9%. A borrower managing comfortable repayments at their current lender may still fail the test at a new lender. APRA has noted lenders can apply exceptions on a case-by-case basis for refinancers. Some non-bank lenders apply a lower buffer for straight refinances with no cash out, which can reopen options for affected borrowers.

Mortgage prison refers to borrowers who are trapped with their current lender because they cannot pass the 3% serviceability buffer at a new lender — even though they are managing existing repayments comfortably. It became more common after successive rate rises in 2024 and 2025. APRA acknowledged lenders can apply buffer exceptions for refinancers on a case-by-case basis. Some non-bank lenders apply a lower assessment buffer for straight refinances, which can provide a pathway. Asking your current lender for a retention rate match is also worth trying first.

Yes. A cash-out refinance may let you access usable home equity for renovations, investment, deposits, debt consolidation or other approved purposes. The lender assesses your property value, LVR, income, expenses, credit conduct and loan purpose — at the 3% buffer rate on the higher loan amount. Accessing equity through refinancing does not trigger capital gains tax. See home equity release for more detail.

LVR is loan-to-value ratio — your loan amount compared with the lender's assessed property value. Below 80% LVR is generally the cleanest refinance band. Below 60% LVR often attracts sharper pricing at many lenders. Above 80% LVR, lenders mortgage insurance may apply. LMI does not transfer between lenders — even if you paid it when you first borrowed, switching above 80% LVR at a new lender means paying it again. If the lender's valuation comes in lower than you expected, a refinance that looked under 80% can tip over.

You may pay lenders mortgage insurance again if your new loan is above the LMI threshold at the new lender — commonly over 80% LVR. LMI is lender-specific and does not transfer between lenders under any circumstances. Even if you paid LMI when you first borrowed, switching lenders above 80% LVR means paying it again. This is why borrowers near the 80% boundary should carefully check the lender's likely valuation and the LMI cost before committing to switch.

Fixed rate break costs are fees charged when you exit, repay or refinance a fixed rate home loan before the term ends. The cost depends on the lender's formula, remaining fixed term, wholesale funding movements and the gap between your fixed rate and current market rates. In some rate environments break costs can be negligible; in others they can be thousands of dollars. Always request a written payout figure from your current lender before approaching any other lender. Never estimate.

Yes, but break costs may apply if the fixed term has not ended. If your fixed term is close to expiry, compare options early so you can move quickly once it reverts to avoid rolling onto the lender's standard variable rate. In 2026, short-term fixed rates at some lenders sit near or below packaged variable rates, so fixing again at expiry may not cost a premium. The right path depends on your rate, break cost, timeline and plans.

Yes. Residential investment property loans can be refinanced to review rates, reset interest-only terms, access equity, consolidate debt or change lenders. Lenders assess rental income, personal income, expenses, other debts, LVR and credit conduct — all at the 3% serviceability buffer. Investor variable rates typically sit 15 to 50 basis points above equivalent owner-occupier rates at the same lender. Portfolio exposure across multiple investment properties is also factored in. See investment property loans for broader guidance.

Yes. Debt consolidation is one of the most common refinance triggers in 2026, driven by cost-of-living pressure. Consolidating credit cards, personal loans or car loans into a home loan at a lower rate can reduce monthly repayments significantly. But short-term debt stretched over 25 to 30 years can cost substantially more in total interest. The structure must genuinely reduce pressure without creating a bigger long-term problem. See home loan debt consolidation.

Common issues include failing the 3% serviceability buffer at the new lender (even if managing current repayments comfortably), low valuation, insufficient equity, LMI recalculation above 80% LVR, poor repayment conduct, credit issues, unstable income, unacceptable cash-out purpose, high total debt-to-income exposure or the loan structure not meeting lender policy. A decline at one lender does not mean no lender will approve it — policy and buffer application varies by institution.

Common refinance mistakes include: not getting a written payout figure before shopping around when on a fixed rate (break costs can be significant); comparing headline rates without checking the comparison rate (fees can reverse the savings); not checking whether LMI applies again when LVR is near 80%; applying to multiple lenders simultaneously (each credit inquiry impacts your file); refinancing shortly before selling (costs won't be recovered); not asking your current lender for a retention rate first; and assuming you qualify for a switch without checking serviceability at the 3% buffer rate on the new loan.

Some lenders offer cashback of up to $3,000 for refinancing, which can offset switching costs. But cashback should not be the main reason to move. A higher cashback on a less competitive rate can still cost more over time. Always check the ongoing comparison rate, features, fees, how long it takes to genuinely recover switching costs and whether the new loan suits your needs beyond the initial incentive.
