Refinancing is the rare financial decision where doing nothing has a price. Lenders routinely offer sharper rates to new customers than to loyal ones, so a loan that was competitive when you took it out drifts towards expensive simply by sitting still. The question is not whether to think about switching, it is whether switching beats staying once you count everything honestly.

When does switching usually win?

  • Your rate has drifted well above what new customers pay. A gap measured in half-percents on a Sydney-sized loan is real money every month.
  • Your equity has grown. If rising values or repayments have pushed your loan below 80% of the property value, you may now qualify for pricing tiers that did not exist for you at purchase.
  • Your loan no longer fits. No offset where you now keep savings, no ability to make extra repayments without penalty, or a fixed period ending onto an uncompetitive revert rate.
  • Your circumstances improved. Higher income, debts cleared, probation finished: you may be assessable by lenders that would not look at you before.

When is staying the better choice?

  • The gap is small once fees are counted. Discharge fees, new-loan setup costs and government registration fees all take a bite. A small rate improvement can take a long time to pay them back.
  • You are inside a fixed term. Break costs can be substantial and are quoted daily by the lender; sometimes waiting out the term is the right call.
  • Your situation would not pass assessment today. Refinancing means requalifying at the current buffered assessment rate. If income has dropped or debts have grown, the loan you have may be better than the loan you would be offered.
  • A phone call fixes it. Lenders have retention teams precisely because keeping you is cheaper than losing you. A repricing request, especially with a competitor’s offer in hand, sometimes closes most of the gap with zero paperwork.

How do you compare loans properly?

The comparison that matters is total cost over the period you will realistically hold the loan: interest rate, ongoing fees, setup and discharge costs, and the value of features you will actually use. An offset account is worth real money to someone who holds savings, and nothing to someone who does not. Cashback offers deserve particular care: they are real dollars, but a cashback attached to a higher ongoing rate is often a loss over any horizon beyond a couple of years. The refinance savings calculator runs the honest version of this comparison.

What does refinancing involve?

A refinance is a smaller version of the original purchase process: application, payslips and statements, a valuation of your property, approval, and settlement between the two lenders, typically a few weeks end to end. You do not deal with the outgoing lender beyond a discharge form. The effort is front-loaded in choosing well, which is exactly the part a broker does with you.

What else should you check about your loan?

How do you work out the break-even point?

The only comparison that matters is how long it takes for the saving to repay the cost of moving. Three numbers do it. First, your annual interest saving: the difference between your current rate and the new rate, multiplied by your loan balance. Second, the total cost of switching: discharge fee from the outgoing lender, any application, valuation or settlement fees from the new one, and the government fees to discharge one mortgage and register another. Third, divide the second by the first. The result is your break-even period in years.

If the break-even is a few months, switching is close to a free decision. If it is two or three years and you might sell, refinance again or fix within that time, the saving may never arrive. The refinance savings calculator runs this with your figures, and it is deliberately built to show the break-even rather than just the headline monthly saving, because the headline is what sells a refinance and the break-even is what justifies it.

Are cashbacks and honeymoon rates worth it?

Three offers deserve a second look before they earn a yes. A cashback is real money on day one, but it is paid for somewhere, usually in a rate that is slightly higher for years; price the cashback against that gap over the period you will hold the loan, not just the first year. An introductory or honeymoon rate reverts to a higher standard rate after a set period, and the revert rate is the one you will pay for most of the loan’s life. And a fixed rate that ends onto an uncompetitive variable rate is the single most common reason people find themselves paying more than new customers without having done anything wrong. Diarise the end of any fixed period and treat it as a refinance decision, because that is what it is.

Can you refinance to release equity?

Switching is also how most people access the equity that rising values have created: to renovate, to consolidate more expensive debt, or to fund a deposit on an investment property. The lender assesses the new, larger loan on your current income and commitments, so a refinance that releases equity is subject to the same buffered serviceability test as any new borrowing. Consolidating a car loan or credit cards into the mortgage can lower your monthly outgoings meaningfully, but spreading a five-year debt over a thirty-year loan costs more in total interest unless you keep the repayments up, which is worth deciding deliberately rather than discovering.

What can go wrong, and how do you avoid it?

  • A valuation below expectations. If your property values lower than you assumed, the new loan may sit above 80% and attract LMI, wiping out the saving. A broker can often sanity-check the likely valuation before an application is lodged.
  • Serviceability has tightened. If your income or circumstances have changed, the loan you hold might be larger than the loan you could be approved for today. This is a reason to check before you give notice to your current lender, not after.
  • Features lost in the move. An offset account balance, a redraw facility with years of extra repayments in it, or a package discount are all things to carry across deliberately rather than lose by default.

What documents and timing does a refinance need?

A refinance needs the same evidence as a purchase: identification, recent payslips or tax returns, statements for the loan you are leaving and your other accounts, and a council rates notice for the property. Lodged complete, most refinances settle within a few weeks, with the valuation and the outgoing lender’s discharge processing being the usual sources of delay. Keep making your existing repayments until the new lender confirms settlement; a missed payment during the changeover is avoidable and reads badly on a credit file.

Questions people ask

How often should I review my home loan?

Once a year is a sensible rhythm, and always at the end of a fixed period or after a significant change in your income, your equity or the market. A review does not commit you to switching; it simply tells you whether staying is still the right decision.

Will refinancing hurt my credit score?

Only slightly: a single application and its credit enquiry is unremarkable. A series of applications in quick succession is not, which is why choosing one lender with advice beats applying to several to see who says yes.

Can I refinance while on a fixed rate?

You can, but break costs apply and can be substantial when rates have moved. Ask your lender for a break cost quote first, then run the break-even test with that cost included. Sometimes the answer is to wait for the fixed period to end.

Rate is the headline, but structure matters too: whether your offset arrangement suits how you actually bank, whether interest-only still serves its original purpose, whether your loan term matches your plans. The free loan health check reviews the whole position, and sometimes concludes you should stay exactly where you are, which is a perfectly good outcome that costs you nothing to learn. If the numbers say switch, Charles handles the comparison and the paperwork from there.
