Your home loan isn't supposed to be a set-and-forget arrangement. The mortgage you took out three years ago was right for where you were then, but life moves, rates shift, and lenders introduce features that didn't exist when you first signed. Knowing when to refinance means paying attention to the signals that your current loan no longer matches where you're heading.
Your Fixed Rate Period Is Ending
When your fixed rate expires, you'll automatically revert to your lender's standard variable rate, which is typically higher than both the fixed rate you were on and the rates being offered to new customers. Most lenders won't notify you until 30 to 60 days before expiry, and by then your options narrow. If you're coming off a fixed rate, start reviewing your loan at least 90 days ahead. That gives you time to compare what your current lender is offering against what's available elsewhere, and to complete a refinance application before the revert rate hits.
Consider a borrower who fixed at 2.19% in early 2021 and is now reverting to a variable rate above 6%. Staying with the same lender on their revert rate could cost an additional $800 or more each month on a $500,000 loan compared to switching to a lender offering a lower variable rate to new customers. Refinancing before expiry means you control the transition instead of accepting whatever rate the lender assigns.
You've Been on the Same Variable Rate for More Than Two Years
Lenders reward new customers with sharper pricing and retain existing customers by quietly increasing their margin over time. If you haven't reviewed your loan in two years or more, you're likely paying a higher rate than someone who just refinanced to the same lender with the same loan amount and deposit. The difference isn't always obvious because your repayments adjust gradually as the Reserve Bank moves rates, but the margin your lender charges on top of the cash rate can widen without you noticing.
A loan health check will show you where your rate sits relative to what's currently available. In many cases, borrowers paying 6.2% on a variable loan could access rates closer to 5.8% or lower by switching lenders, which on a $600,000 loan saves around $140 per month. That's $1,680 a year for a process that takes a few weeks and costs a fraction of what you'll save.

You Need to Access Equity for Your Next Property
If your property has increased in value and you want to use that equity to fund a deposit on an investment property or upgrade, refinancing is often the cleanest way to release those funds. Rather than taking out a separate top-up loan or applying for a second mortgage, refinancing lets you increase your loan amount and structure it properly from the start, usually with an offset account attached so the extra funds don't cost you interest until you use them.
In a scenario like this, a borrower with a property now valued at $850,000 and an outstanding loan of $480,000 has around $200,000 in usable equity after allowing for an 80% loan-to-value ratio. Refinancing to access $100,000 of that equity gives them the deposit for their next purchase without selling or dipping into savings. The new loan structure can split the borrowing between owner-occupied and investment portions, each with the right rate and offset setup. Trying to bolt that onto an old loan rarely works as cleanly.
Your Loan Doesn't Have the Features You Now Need
When you first bought, an offset account or redraw facility might not have mattered. Now, with a higher income or irregular bonuses, you want somewhere to park extra cash and reduce interest without locking it away. If your current loan doesn't offer an offset, or if it does but charges a higher rate for the privilege, refinancing to a loan with a genuine 100% offset at a lower rate makes sense. Some lenders also restrict redraw or charge fees to access your own money, which becomes frustrating the moment you need flexibility.
You're not refinancing to chase features for the sake of it. You're refinancing because the way you manage money has changed and your loan structure should reflect that. A loan that worked when you were stretching to cover repayments might not suit you now that you're ahead and want to minimise interest on the balance.
You Want to Consolidate Debt Into Your Mortgage
If you're carrying personal loan debt, car finance, or credit card balances at rates between 8% and 20%, consolidating that into your mortgage at a lower rate can improve your cashflow immediately. Refinancing lets you increase your home loan to clear those higher-interest debts, leaving you with one repayment at a lower overall rate. The trade-off is that you're securing previously unsecured debt against your property and extending the repayment term, so this only makes sense if you're committed to not running up the same debts again.
The monthly saving can be significant. A borrower with $30,000 across a car loan at 9% and credit cards at 18% might be paying $1,200 a month in repayments. Rolling that into a mortgage at 6% drops the interest cost substantially, though spreading it over 30 years means paying more in total unless you keep making higher repayments and clear it sooner.
When Refinancing Doesn't Make Sense Right Now
Not every rate difference is worth acting on. If you're within 12 months of paying off your loan, or if the rate saving is less than 0.3% and you're planning to sell within two years, the upfront costs and time involved outweigh what you'll save. Refinancing also doesn't make sense if your property value has dropped and you no longer meet lending criteria, or if your income or employment situation has changed in a way that affects your ability to borrow the same amount.
Sometimes your current lender will negotiate if you let them know you're considering a switch. That's not guaranteed, but if you're a long-term customer with a solid repayment history, it's worth asking before you commit to a full refinance process. If they can't move, at least you know you tried.
Refinancing works when it aligns with where you're going, not just because a lower rate exists. If your loan no longer fits your income, your goals, or the value sitting in your property, that's when it's time to move. Call one of our team or book an appointment at a time that works for you.
Frequently Asked Questions
When should I refinance after my fixed rate period ends?
Start reviewing your options at least 90 days before your fixed rate expires. This gives you time to compare your lender's revert rate against other offers and complete a refinance application before you're automatically moved to a higher standard variable rate.
How much can I save by refinancing to a lower rate?
A 0.4% rate reduction on a $600,000 loan saves around $140 per month, or $1,680 per year. The actual saving depends on your loan amount, the rate difference, and how long you hold the new loan.
Can I refinance to access equity in my property?
Yes, refinancing lets you increase your loan amount to access equity for a deposit on another property or other purposes. You can typically borrow up to 80% of your property's current value without needing mortgage insurance.
Is refinancing worth it if I've only been on my current loan for two years?
It depends on the rate difference and your plans. If you're paying 0.4% or more above current rates and you're not planning to sell soon, refinancing can still make financial sense even after a short period.
What costs are involved in refinancing a home loan?
Typical costs include a discharge fee from your current lender (usually $150 to $400), application fees with the new lender (often waived), and valuation or settlement fees. These are usually outweighed by the interest saved within the first year.
