Most of us are good at putting things off when they feel complicated. Booking that appointment, sorting out the filing, reviewing the home loan. Life is busy, and as long as the repayments are leaving your account on time, it is easy to assume everything is fine.

But here is the thing. With your mortgage, the cost of doing nothing is not neutral. Every month you stay on an uncompetitive rate is a month you are paying more than you need to. And over two or more years, that gap adds up to a number that tends to surprise people when they finally see it.

Let’s look at what that cost looks like in real dollars, and why fixing can be far simpler than most people expect.

Why Homeowners Put Off Reviewing Their Loan

According to a recent Canstar survey of almost 3,000 homeowners, over half (52%) have never changed their home loan provider. Another 31% haven’t switched in the last two years.

It is not laziness. It is how refinancing has traditionally been positioned. People imagine a mountain of paperwork, long phone calls, and weeks of uncertainty. They assume the savings probably will not justify the hassle.

Add to that the fact that most Australian homeowners do not actually know their current interest rate. If you do not know your starting point, it is hard to feel motivated to look for something better.

The result? Most people just stick with what they have. Your loan quietly keeps ticking along, and you quietly keep paying whatever rate your lender set for you, sometimes years ago, in a completely different market.

What the Market Has Been Doing While You Waited

The Australian lending market does not stand still. Lenders compete aggressively for new business, which means they regularly offer sharper rates to attract new customers. Existing customers who do not ask for a better deal rarely receive one.

In practice, this creates a loyalty gap. Long-term borrowers end up paying a higher rate than someone who just walked through the door and signed up with the same lender. It is not a penalty for loyalty in any official sense, but the financial effect is identical.

More than 640,000 Australian mortgages were refinanced in 2025, a 20% increase on the year before^[1]. Those borrowers did not all have compelling reasons to move. Many simply did the numbers and decided they were paying too much.

In Real Terms

Here is where it gets concrete.

Imagine you took out a home loan of $680,000 five years ago at an interest rate of 7%.

Now imagine that a competitive rate in the current market is sitting at 5.9%. A difference of 1.1% sounds small.

If you were to refinance to a 5.9% interest rate, with 25 years remaining on your loan, this could save you over $11,700 over the next two years, without factoring in fees and switch costs.

In other words, loyalty to your home loan provider could end up costing you over $11,000.

The Hidden Cost Is Time, Not Just Money

This year alone, Australia has had three rate increases, pushing many borrowers’ rates up by 0.75%. Now imagine that a competitive rate in the current market sits at 5.9%.

Staying loyal to your current home loan provider, especially during a period of rate hikes, may cost you far more than you realise, both in dollars and in peace of mind. Every month you delay a review is another month you pay the difference. There is no catch-up mechanism. The money spent on an uncompetitive rate does not come back.

This is worth sitting with for a moment, not to create alarm, but to make the cost concrete. Inaction is not a neutral choice. It is a choice to keep paying a rate the market has already moved past.

The good news is that the fix is rarely as involved as people fear.

Let the experts do the work for you

Refinancing has a reputation for being complicated, but for most straightforward residential loans, the process is far more manageable than it was even a few years ago. An experienced mortgage broker will assess your situation, compare options across a wide panel of lenders, and handle the legwork, including negotiating with either your existing lender, or new lenders, on your behalf.

You are not starting from scratch. You already own the property, you have a repayment history, and you know what you need from a loan. That puts you in a strong position.

The typical refinancing process involves a conversation with your broker, some supporting documents, and a formal application. In many cases, the whole process might be wrapped up within a few weeks. For most borrowers, the savings begin once the new loan settles.

Your Next Move

If you have not looked at your home loan in the past two years, now is a straightforward time to do it. The market may have shifted, and there is a reasonable chance you are paying more than you need to.
