When Should You Refinance Your Home Loan? The Complete Australian Guide

Most Australians take out a home loan and forget about it — trusting that their bank is offering a fair rate and that the loan terms still suit their circumstances. In practice, the gap between a lender's advertised new customer rate and the rate they charge loyal existing customers — the so-called loyalty tax — can reach 0.5% to 1.0% per annum. On a $600,000 loan, a 0.7% loyalty tax costs approximately $4,200 extra every year. Refinancing is not just a financial manoeuvre for those in trouble; it's a standard part of proactive mortgage management for any informed borrower.

How Do You Know When to Refinance?

The most straightforward trigger is a rate gap. If your current interest rate is 0.3% or more above the best available rate for your borrower profile, a detailed refinancing analysis is warranted. The calculation must account for the costs of switching (discharge fee, break costs if exiting a fixed rate, new loan establishment fees, and any valuation costs) against the ongoing interest saving — expressed as a break-even period in months.

"The loyalty tax is real. Lenders routinely offer better rates to new customers than to borrowers who've been loyal for five or ten years."

Situations Where Refinancing Makes Clear Sense

• Your rate hasn't been reviewed in more than 12 to 18 months and market rates have moved
• Your property has increased in value, reducing your LVR below 80% and making you eligible for better-priced products
• You want to access equity for a renovation, investment property deposit, or debt consolidation
• Your financial circumstances have improved (higher income, reduced debt) and you now qualify for products that weren't available when you first borrowed
• You're coming off a fixed rate period and the revert variable rate is uncompetitive
• Your current loan lacks features you now value — such as an offset account or a redraw facility

The True Cost of Refinancing

Refinancing has real costs that must be weighed against the projected savings. Discharge fees (to close your existing loan) typically range from $150 to $400 for variable rate loans. Fixed rate loans may carry break costs — which can be substantial and depend on the remaining term, current and contract rates, and the lender's calculations. New loan establishment fees vary from zero to approximately $700. Most cashback refinance offers (currently ranging from $2,000 to $4,000) are designed to offset these switching costs, though they should not be the primary reason to refinance to a suboptimal product.

Cashback Refinancing: Is It Worth It?

Several Australian lenders offer cashback incentives between $2,000 and $4,000 to borrowers who refinance from another institution. These offers are attractive but come with conditions — typically a minimum loan size ($250,000+), a requirement to maintain the loan for a minimum period (two to three years), and sometimes a slightly higher rate than the lender's non-cashback product. A broker can model the total cost of ownership of a cashback product versus a lower-rate non-cashback product over your expected holding period, ensuring you make the right call.

Equity Access: Refinancing to Release Funds

Australian property values in many markets have grown significantly over recent years, creating substantial equity in existing properties. Refinancing to access this equity — either via a loan top-up or a new facility — is a common strategy for property investors building their portfolio, homeowners undertaking renovations, or borrowers consolidating higher-rate personal debt. When accessing equity, it's critical to consider how the additional borrowing affects your overall debt position, serviceability for future purchases, and tax position if the funds are used for both investment and personal purposes.

The Refinancing Process: What to Expect

1. 1Assessment — your broker reviews your current loan, rate, features, and remaining term against the market
2. 2Comparison — shortlisted lenders are presented with rate, features, cashback offers, and total cost modelled
3. 3Application — broker prepares and lodges the new application with your chosen lender
4. 4Valuation — the new lender orders a property valuation (usually AVM for standard refinances, physical valuation for higher LVR or complex properties)
5. 5Approval and discharge — the new lender approves the loan, coordinates discharge of the existing loan, and settles
6. 6Settlement — typically 30 to 45 days from application to settlement for a standard refinance
