Refinancing in Australia: a surge in 2025 and why timing still matters

As Australia heads deeper into 2025, refinancing is resurfacing as a powerful tool for home owners.

Over the past year more than 500,000 loans were refinanced, fuelled by a notable 33 per cent increase in internal refinancing where borrowers either negotiated better terms with their current lender or drew equity for other purposes.

In the March quarter alone, around 65,000 loans were switched between lenders — a 5.1 per cent rise on the previous quarter — marking the third straight quarterly increase.

Lenders are reacting with attractive offers: fixed home loan rates with some lenders have dipped below 5 per cent, while several institutions have trimmed both fixed and variable rates in anticipation of further Reserve Bank reductions.

Experts estimate that as many as 1.2 million Australians could substantially benefit from refinancing — potentially unlocking up to $1.2 billion in collective savings through lower rates and equity leverage.

Nevertheless, refinancing isn’t always the right decision.

Speaking to Australian Property Investor Magazine, Carolyn Xaftellis, Senior Mortgage Specialist at Specialist Mortgage, outlined five key scenarios in which borrowers may be better off remaining with their current mortgage.

1. Too soon in the loan’s life

In the early years, most mortgage repayments go towards interest, meaning the principal barely budges.

Refinancing too early effectively resets the clock, potentially extending the repayment horizon and negating interest savings. It can take many years before the rate advantage outweighs the lost principal repayment momentum.

To avoid extending your repayment timeline, you have two choices: maintain the same loan term; increase your repayments so the new loan is paid off on the same date as your current loan.

2. Steep break costs for fixed rate loans

Breaking a fixed rate loan early can be costly.

Lenders calculate break costs based on the interest margin they miss out on. For example, terminating a fixed loan of $500,000 at 6 per cent when current rates are around 3 per cent could mean years of forgone interest — and a hefty break cost to match.

Anyone considering refinancing mid-term must weigh these charges carefully before pulling the trigger.

3. Weakened borrower profile

If your financial or credit profile has declined, refinancing with favourable terms may not be possible.

Lenders assess credit history, income stability, and equity when setting rates. If your credit score isn’t as strong or your circumstances have shifted unfavourably, sticking with your existing lender may be safer than risking a higher rate or rejection elsewhere.

4. Planning to sell soon

Refinancing involves costs: application, valuation, and legal fees, and possibly break costs.

If you’re likely to sell the property before you recoup these expenses, refinancing may prove counterproductive.

The “break-even point” — when cumulative savings offset the upfront cost — is critical here. Selling early means there’s often no time to reach that point.

5. Limited equity

Lenders favour borrowers with substantial equity. If your property’s market value has declined — or you’ve yet to build much equity — your loan-to-value ratio (LVR) may be too high to secure a competitive refinance offer. In such cases, staying put or waiting for equity to grow may be prudent.

How to time refinancing wisely

Refinancing is about timing as much as it is about interest rates.

Calculate the break-even period

Using a real-world example: suppose you switch to a lender offering a 1 per cent lower rate. On a $600,000 loan that could equate to $1,200 in savings per year — or over $20,000 across two years, even after typical switching fees (estimated at $1,150).

Leverage rising property values

Many Australians now hold improved equity due to recent property price gains. Average refinance loan amounts are around $566,000, slightly higher than other new loans at $660,000 or so. Greater equity strengthens your negotiating power and may unlock better rate discounts.

Use technology to your advantage

Banks like Westpac report a 45 per cent quarterly increase in refinancers, with 30 per cent of home owners considering a switch and expecting a faster, digital process. If convenience and speed matter, prioritising lenders with streamlined online processes may reduce hassle.

Watch RBA moves and rate trends

With inflation cooling and the RBA expected to cut the cash rate further, several banks are pre-emptively adjusting their offers.

Fixed and variable rates have fallen — but real savings only materialise once cuts are passed on, and after comparing features like offset accounts.

Pulling the refinancing trigger

Refinancing can save thousands — particularly when property values are rising and lender competition is strong but it’s not a universal fix.

Borrowers must assess costs, equity, timing and eligibility carefully.

For many, consulting a mortgage broker or using a reliable loan comparison tool is the best path forward. With thoughtful strategy, the move may just pay off — literally.
