Should You Refinance Your Home Loan in 2026? A Guide for South Australian Homeowners

18/4/2026

With the RBA cash rate at 4.10% and variable rates sitting between 6% and 7%, thousands of SA homeowners are paying more than they need to. Here is how to tell if refinancing makes sense for you, and what to watch out for.

If you took out your home loan more than two years ago, there is a good chance the rate you are paying today bears little resemblance to the one you signed up for. Banks rely on a well-documented pattern called "loyalty tax," where existing customers quietly drift onto higher rates while new customers receive sharper pricing. The difference can be hundreds of dollars every month.

Refinancing is not always the right move. But if you have not reviewed your loan in the past 24 months, you owe it to yourself to find out where you stand.

How the Loyalty Tax Works

When you first took out your home loan, your lender likely offered a competitive rate to win your business. Over time, two things happen. First, the RBA changes the cash rate and your lender adjusts your variable rate, but not always by the same amount or in the same direction. Second, the lender introduces newer, sharper products for new customers while leaving existing borrowers on older, more expensive products.

The result is a gap between what you pay and what the market offers. In the current environment, that gap can be 0.5% to 1.0% or more. On a $500,000 loan, a 0.5% reduction translates to roughly $160 per month, or nearly $2,000 per year.

The only way to know your gap is to compare your current rate against what 35+ lenders are offering right now.

Five Signs It Might Be Time to Refinance

1. You Have Not Reviewed Your Rate in Over Two Years

This is the simplest indicator. If your last rate review was before 2024, the market has moved substantially. Even if the RBA has raised rates, the competitive landscape among lenders has shifted, and you may find a meaningfully better deal.

2. Your Property Value Has Increased

If your home is worth more than when you bought it, your loan-to-value ratio (LVR) has improved. A lower LVR makes you a lower-risk borrower in the eyes of lenders, which can unlock better pricing and product features. This is particularly relevant for borrowers who originally purchased with a high LVR and paid Lenders Mortgage Insurance (LMI). If your equity has grown past the 20% threshold, you are now in a different pricing tier entirely.

3. You Are Juggling High-Interest Debts

If you have credit cards, personal loans or car finance alongside your mortgage, debt consolidation through a refinance can simplify your finances and reduce the total interest you pay. Rolling higher-rate debts into a lower-rate mortgage can free up significant monthly cash flow, though it is important to understand the trade-offs (you are spreading that debt over a longer term).

4. Your Needs Have Changed

Perhaps you want an offset account your current loan does not offer. Or you need to access equity for renovations. Or your fixed rate period is about to expire and you want to lock in again. Changes in your financial life often mean the loan that was right three years ago is no longer the best fit.

5. You Are on a Honeymoon Rate That Has Expired

Many lenders offer an introductory rate for the first one to two years. Once it reverts to the standard variable rate, you may find yourself paying well above the market. This is one of the most common, and most costly, traps for homeowners who do not actively monitor their loan.

What to Watch Out For When Refinancing

Refinancing is not free, and it is not always beneficial. Before you switch, make sure you understand the costs involved.

Break Costs on Fixed Rate Loans

If you are currently on a fixed rate, breaking that contract early can attract significant fees. Break costs are calculated based on the difference between your fixed rate and the current wholesale rate, and can run into thousands of dollars. Always get a break cost quote from your current lender before committing to a switch.

Discharge and Application Fees

Your existing lender may charge a discharge fee to release your mortgage. The new lender may charge an application or establishment fee. In many cases, these are modest (a few hundred dollars) and are quickly offset by the savings on a better rate, but they should be factored into your decision.

Lenders Mortgage Insurance (LMI)

If your equity is below 20%, switching lenders may trigger a new LMI premium. This can add thousands of dollars to the cost of refinancing and may eliminate the benefit of a lower rate. A broker can help you identify lenders that offer LMI waivers or structure the loan to avoid this cost.

Resetting Your Loan Term

If you refinance a 25-year loan that you have been paying for five years into a new 30-year loan, you have just added 10 years of interest. Make sure you compare like for like, and consider keeping your repayments at the same level even if the new minimum is lower.

Refinancing on the Fleurieu Peninsula or Adelaide Hills

If your property is on acreage, in a rural living zone, on tank water, or has any characteristics outside the standard suburban template, refinancing can be more complex than simply shopping for a lower rate.

Not all lenders will accept rural-zoned properties, larger land parcels, or homes with non-standard services. Some lenders require local valuers while others send generalist valuers from Adelaide who may not understand local market conditions. A property that is perfectly mortgageable with the right lender can be rejected outright by the wrong one.

This is where working with a broker who understands regional lending makes a measurable difference. We know which lenders accept Fleurieu and Hills properties, which valuers understand the local market, and how to structure a refinance application to avoid unnecessary delays or rejections.

How Much Could You Save?

The answer depends on your loan balance, current rate, remaining term and what the market is offering. Here are some indicative examples:

Scenario 1: $450,000 loan, 0.4% rate reduction Monthly saving: approximately $120 Annual saving: approximately $1,440 Saving over remaining 25-year term: approximately $36,000

Scenario 2: $600,000 loan, 0.6% rate reduction Monthly saving: approximately $240 Annual saving: approximately $2,880 Saving over remaining 25-year term: approximately $72,000

These are indicative figures only. Your actual saving will depend on your specific circumstances. Use our repayment calculator to run your own numbers, or try the repayment frequency calculator to see how switching to fortnightly payments could accelerate your loan payoff.
