When to refinance and why timing matters

The right time to refinance is when the financial benefit outweighs the cost of switching, and that calculation changes based on your loan balance, your current rate, and what you're trying to achieve.

Your fixed rate period is ending

If your fixed rate period is about to expire, you have a narrow window to act before reverting to your lender's standard variable rate, which is typically higher than what new customers receive. Most lenders allow you to apply for a refinance around 90 days before your fixed term ends, and settlement can occur on or just after the expiry date. This timing means you avoid break costs while securing a more competitive rate before the reversion happens.

Consider a borrower in Hornsby who fixed at 2.1% three years ago on a loan balance of $550,000. With that fixed period ending, their lender's reversion rate sits at 6.5%, while new variable rates for existing customers are closer to 6.2%, and refinance rates with other lenders are available around 5.9%. Refinancing before the expiry locks in the lower rate without penalty, and over a remaining 25-year term, even a 0.3% difference can mean tens of thousands in interest saved. The application timeline matters because lenders need time to value the property, assess your financial position, and prepare settlement, so starting the conversation three months out is standard practice.

If you're approaching the end of a fixed term, a loan health check will show you what rates are available now and whether refinancing makes sense based on your remaining balance and loan term. You can also explore your options on our fixed rate expiry page.

You're stuck on a rate well above the current market

If you haven't reviewed your loan in several years and you're on a variable rate above 6.3%, or a fixed rate above 6.0%, you're likely paying more than necessary. Lenders regularly offer lower rates to new customers than they do to existing borrowers, and the gap can be significant. Refinancing to a lower rate reduces your monthly repayment, shortens your loan term if you keep payments the same, or both.

The cost of refinancing typically includes a discharge fee from your current lender, application or establishment fees with the new lender, and valuation costs. In Hornsby, where property values have held relatively steady and many homes sit above the $1 million mark, the loan-to-value ratio is often low enough that lenders waive some fees or offer cashback incentives to attract the business. If your loan balance is above $400,000 and the rate difference is 0.4% or more, the benefit usually justifies the cost within the first year.

You need to access equity for investment or renovation

Refinancing lets you access equity in your property without selling it. If your property has increased in value or you've paid down a significant portion of your loan, you may be able to borrow against that equity for a deposit on an investment property, a renovation, or another purpose. This is sometimes called a cash-out refinance, and it works by increasing your loan amount while staying within the lender's loan-to-value ratio limits.

In Hornsby, where the median property value has appreciated over the last decade, many homeowners have built substantial equity without realising it. A property purchased ten years ago may now be worth considerably more, and if your current loan balance is less than 60% of the updated valuation, you may be able to access equity while still securing a competitive rate. The lender will require a current valuation, and your borrowing capacity will depend on your income, expenses, and the purpose of the funds. If you're using the equity to purchase an investment property, the rental income from that property can be included in your servicing calculation, which can improve your borrowing capacity.

Your loan no longer fits your financial situation

Refinancing isn't always about the interest rate. Sometimes your loan structure no longer matches the way you use your money. If you're paying into a loan without an offset account but you regularly hold cash savings, switching to a loan with an offset can reduce the interest you're charged without requiring you to pay extra into the mortgage. If you've accumulated multiple debts with higher interest rates, such as personal loans or car loans, consolidating them into your mortgage can reduce your overall monthly repayment and improve cashflow.

As an example, a borrower with a $480,000 home loan, a $25,000 car loan at 8%, and $15,000 in personal debt at 12% might be managing three separate repayments each month. Refinancing the home loan to $520,000 and clearing the other debts consolidates everything into a single repayment at the mortgage rate. The total monthly outgoing drops, and the higher-interest debts are eliminated. The trade-off is that those debts are now secured against the property and stretched over the remaining mortgage term, so the total interest paid over time may be higher unless the borrower continues to make additional repayments.

This approach works when the goal is to improve cashflow or simplify finances, not necessarily to reduce total interest. It's worth modelling both scenarios before proceeding.

The features you need aren't available on your current loan

Some older loan products don't include the features that are now standard, such as offset accounts, redraw facilities, or the ability to split your loan between fixed and variable portions. If your current loan limits how you can manage your repayments or access funds you've paid ahead, refinancing to a loan with the features you need can give you more control without necessarily changing your repayment amount.

Hornsby has a high proportion of dual-income households and professionals who value flexibility in how they manage their mortgage. An offset account linked to your home loan reduces the interest charged on your loan balance by the amount held in the offset, and it keeps your savings accessible. A redraw facility lets you withdraw extra repayments you've made, though some lenders restrict how often you can redraw or charge fees for doing so. If your current loan doesn't offer these options, refinancing opens them up.

When refinancing doesn't make sense

Refinancing has a cost, and if your loan balance is low, your remaining term is short, or the rate difference is minimal, the upfront cost may outweigh the benefit. If your loan balance is under $200,000 and you're within five years of paying it off, the interest saved by refinancing may not cover the fees involved. Similarly, if you're planning to sell the property within the next two years, refinancing may not deliver enough benefit before you exit the loan.

If you're currently on a fixed rate and want to refinance before the term ends, you'll likely face break costs, which can run into the thousands depending on how much time remains and how far rates have moved since you fixed. Break costs are calculated based on the difference between your fixed rate and the current wholesale rate for the remaining term, and they're designed to compensate the lender for the lost interest. In some cases, the break cost alone makes refinancing unviable until the fixed period expires.
