Refinancing Your Perth Home Loan — When and How in 2025

With interest rates having moved significantly over 2022–2024 and competition among lenders remaining strong, refinancing your Perth home loan can deliver meaningful savings. But refinancing isn't always the right move — here's how to think through the decision.

When Refinancing Makes Sense

A better rate is available: If you've been with the same lender for more than two years and haven't negotiated your rate recently, there's a strong chance you're paying above the best available rate. Even a 0.5% rate reduction on a $600,000 Perth mortgage saves approximately $3,000 per year in interest.

Debt consolidation: Rolling high-interest debts (personal loans, car loans) into a home loan at a lower interest rate can reduce your total monthly repayments, though it may increase the total interest paid over time if the term is extended. Discuss with a financial adviser.

Access equity: Refinancing can provide access to equity built up in your Perth property — for renovations, investment, or other purposes. Cash-out refinancing is a common strategy among Perth homeowners in areas that have seen strong price growth.

A Worked Example of Potential Savings

Perth homeowner with $650,000 remaining on a 25-year mortgage at 6.4% with their existing lender. Refinancing to a lender offering 5.9% (a 0.5% difference) saves approximately $3,250 per year in interest — $270 per month. Over five years, that's over $16,000 in interest savings before accounting for any costs.

Costs of Refinancing

Refinancing is not free. Typical costs include: discharge fee from your existing lender ($150–$400), new application or establishment fee ($0–$600 depending on lender), property valuation fee ($200–$400), and possibly Lenders Mortgage Insurance if your equity is below 20% (significant — avoid this if possible). Total costs are commonly $500–$1,500 for a straightforward refinance. Break-even time at the savings rate above is typically 2–6 months.

Break Costs for Fixed Rates

If you're currently on a fixed rate home loan in Perth, breaking the fixed period to refinance may incur substantial break costs — potentially thousands of dollars. These are calculated by the lender based on wholesale interest rate movements and are not easily predictable. Always get a written break cost estimate from your current lender before proceeding with refinancing a fixed rate loan.

Cashback Refinancing — The Catch

Some Perth lenders offer cashback incentives of $2,000–$4,000 to attract refinancers. These can be attractive — but check the interest rate carefully. A lender offering $3,000 cashback at a rate 0.3% higher than the market saves you money upfront but costs you more over time. Run the full-term numbers, not just the cashback headline.
