Refinancing should improve your position, not simply move your mortgage from one bank to another. The headline rate is only one part of the decision. A good review compares the repayment change, switching costs, remaining loan term, loan features and whether the new lender will support your future plans such as investment purchases or equity releases.
- Calculate switching costs and break-even
- Compare loans over the same remaining term
- Check annual/package fees and loan features
- Consider future equity and investment plans
- For investment debt, check the structure before mixing purposes
Start with the break-even point
Add the genuine switching costs: discharge fees, registration costs, valuation or application fees, and any package fees. Compare those costs with the expected monthly saving. Dividing costs by monthly savings gives a simple break-even period.
A short break-even period can be attractive, but it should not be the only test. A refinance can still be poor value if it extends the loan term and you simply spend the lower repayment.
Do not reset the clock by accident
If you have 22 years remaining and refinance into a fresh 30-year loan, the required monthly repayment may fall sharply even without much rate improvement. That can feel like a saving while increasing the total time in debt.
A more meaningful comparison is to model the new loan over the remaining term, then decide deliberately whether you want a longer term for cash-flow flexibility.
Look beyond the rate
Offset accounts, redraw, interest-only options, serviceability policy, valuation outcomes and future cash-out rules can matter as much as a small rate difference. The cheapest lender today may not be the most useful lender for your next move.
For investors, loan purpose and tax tracing also need to be considered before consolidating or restructuring debt.
Frequently asked questions
How often should I review my home loan?
A yearly review is a sensible habit, and you should also review after major rate changes or changes in your financial goals.
Is a cashback enough reason to refinance?
Usually not by itself. Treat cashback as one line in the total cost comparison.
Can refinancing reduce my monthly repayment but cost more overall?
Yes. Extending the loan term can lower monthly repayments while increasing total interest over time.
