Avoid these 4 Mistakes When Switching Fixed to Variable

If your fixed rate period is ending and you're considering a switch to variable, the timing of that decision can save or cost you thousands.

Most fixed rate home loans in Paddington were locked in during the low-rate period a few years back, with rates between 2% and 3%. Those fixed periods are now expiring, and many borrowers are rolling onto their lender's standard variable rate without comparing what else is available. The difference between your lender's revert rate and a competitive variable rate can be significant, particularly in a suburb where property values have continued to climb and equity positions have strengthened.

Switching Before Your Fixed Rate Ends: When Break Costs Apply

If you want to refinance before your fixed rate period expires, your current lender will charge break costs. These are calculated based on the difference between your fixed rate and the wholesale rate your lender can now get for the remaining term. The closer you are to the end of your fixed period, the lower the break cost tends to be. For a loan with six months remaining on a fixed term, break costs might be $2,000 to $5,000 depending on your loan amount and how much rates have moved since you fixed. If you have only a few weeks left, it may be negligible or zero.

Consider a scenario where a Paddington homeowner with 18 months remaining on a 2.5% fixed rate wants to switch to variable. The lender calculates that they would lose interest income over that period because current fixed rates are lower than the original 2.5%. Break costs come back at $12,000. The borrower decides to wait until closer to expiry, refinances three months out when break costs drop to $800, and moves to a variable rate that saves $300 per month. Within three months, the saving has covered the cost.

What Happens When Your Fixed Rate Period Ends

When your fixed rate period expires, your loan automatically converts to your lender's standard variable rate unless you take action. Standard variable rates are typically higher than the advertised rates offered to new customers. You are not locked in after expiry, so there are no break costs if you refinance at that point. Most lenders send a notification 30 to 90 days before your fixed period ends, but that notice does not always make it clear that you could be moving to a rate that is 0.5% to 1% higher than what is available elsewhere.

In our experience, many Paddington borrowers assume their lender will offer them a competitive rate automatically. That does not happen. If you want a lower rate, you either need to negotiate with your current lender or refinance to a new one. Timing the application so that settlement occurs within a few weeks of your fixed rate expiry avoids both break costs and extended periods on a high revert rate.

Fixed to Variable: Why the Switch Makes Sense for Some Borrowers

Switching from fixed to variable gives you access to offset accounts and redraw facilities, which most fixed rate loans restrict or do not offer. An offset account linked to your variable rate home loan reduces the interest you pay by offsetting your savings balance against your loan amount. If you have $30,000 sitting in an offset account against a $500,000 loan, you only pay interest on $470,000. That feature alone can save more over time than a marginal rate difference, particularly if you keep a buffer in your offset for upcoming expenses or investment opportunities.

Variable rates also give you flexibility to make extra repayments without penalty, which can reduce your loan term and total interest paid. If you are in a stable income position and want to pay down your mortgage faster, variable suits that approach. Fixed rates lock in certainty, but they also lock out flexibility.

Timing Your Refinance Application Around Fixed Rate Expiry

Most refinance applications take three to six weeks from submission to settlement, depending on the lender and how quickly you provide documentation. If your fixed rate ends in two months, starting the refinance process now means you can settle just after expiry and avoid both break costs and time on the revert rate. Leaving it until after expiry means you could spend several weeks or even months on your lender's standard variable rate while the new loan is processing.

As an example, a Paddington borrower with a fixed rate ending in mid-September contacts a broker in early August. The application is submitted within a week, the valuation is completed in ten days, and the loan is approved and ready to settle by late September. The borrower switches to a variable rate with an offset account and a rate 0.7% lower than the revert rate they would have been moved to. On a $600,000 loan, that difference saves over $4,000 in the first year.

Offset Accounts and Redraw: What You Gain by Moving to Variable

Most variable rate home loans include either an offset account or redraw facility, and some offer both. An offset account is a separate transaction account where your balance reduces the interest charged on your loan. Redraw lets you access extra repayments you have made above the minimum. Offset accounts are more flexible because the funds remain accessible at any time without needing to request a redraw, and they do not re-amortise your loan.

For Paddington households with variable income or upcoming expenses such as renovations, school fees, or investment property purchases, keeping funds in an offset account rather than paying them directly off the loan gives you liquidity while still reducing interest. If you are considering a renovation on one of the area's character Queenslanders or planning to buy an investment property in the inner city, that liquidity can be the difference between moving quickly on an opportunity or needing to reapply for finance.

Should You Refinance or Negotiate with Your Current Lender?

Before committing to a refinance, it is worth contacting your current lender to ask what rate they can offer when your fixed period ends. Some lenders will match or come close to competitor rates if you ask, particularly if you have equity and a clean repayment history. If they offer a rate that is within 0.1% to 0.2% of what you could get elsewhere and you are happy with your current loan features, staying put may make sense.

If the gap is larger, or if your current loan does not include an offset account or the flexibility you need, refinancing will likely deliver a outcome that justifies the effort. A home loan health check with a broker gives you a clear comparison of what your current lender is offering against what is available across the market, including features, rates, and fees.

What You Need to Refinance When Coming Off a Fixed Rate

The documentation required to refinance is similar to your original home loan application: recent payslips, tax returns if you are self-employed, bank statements, and a current property valuation. Lenders will also want to see your most recent loan statement and details of your fixed rate expiry date. If your income or employment has changed since you first took out the loan, that may affect serviceability, but in most cases, Paddington property values have increased enough that your loan-to-value ratio has improved, which can work in your favour.

Processing times vary by lender, but most brokers can help you choose a lender with faster turnaround times if you are working to a fixed rate expiry deadline. If your fixed period ends in less than four weeks, some lenders may still be able to process the application in time, but it becomes tight.

Refinancing when your fixed rate ends is one of the few moments where inaction has a measurable cost. If you are within three months of expiry, call one of our team or book an appointment at a time that works for you to review your current loan and compare what is available.
