Avoid These 5 Mistakes When Refinancing to Change Loan Terms

Refinancing to change your loan terms isn't just about chasing a lower rate.

Many Mornington Peninsula homeowners refinance to adjust their loan structure, whether that's switching from fixed to variable, shortening or extending the loan period, or adding features like an offset account. The decision usually stems from a change in circumstances or a realisation that the current loan no longer fits how they use their property or manage their finances.

Refinancing Without Understanding What the New Terms Actually Cost

Changing your loan term affects more than just your repayment amount. A shorter loan term reduces the total interest you pay over the life of the loan, but it increases your monthly repayments. A longer term does the opposite. The difference in total interest paid can be substantial, even if the rate stays the same.

Consider a borrower who refinances to extend their remaining 20-year term back out to 30 years to reduce monthly repayments by several hundred dollars. The immediate cashflow relief is real, but if they don't account for the additional years of interest, they may end up paying tens of thousands more over the life of the loan. In our experience, this decision works well when the freed-up cashflow is redirected into an offset account or investment, but it rarely makes sense if the extra repayment capacity is simply absorbed into lifestyle spending.

Switching From Fixed to Variable Without a Rate Lock Strategy

Many borrowers coming off a fixed rate period assume they should switch to variable by default. That's not always the case, particularly when fixed rates are lower than variable or when you expect rates to rise in the near term.

If your fixed rate period is ending and you want the flexibility of a variable loan, the timing of your refinance application matters. Lenders typically offer a rate lock for 90 days, but if your current fixed rate doesn't expire for another four months, you may miss the opportunity to lock in a lower rate before it moves. We regularly see this with clients in Mount Eliza and Mornington who start the refinance process too early or too late and end up on a rate higher than what was available a few weeks prior. The fixed rate expiry window is when most borrowers should be reviewing their options, not after the rate has already reverted.

Ignoring the Features You'll Actually Use

Refinancing to access features like an offset account or redraw facility only makes sense if you'll use them. An offset account reduces the interest you pay by offsetting your savings balance against your loan balance. But if you don't consistently hold savings in that account, you're paying for a feature that delivers no benefit.

As an example, a Rosebud property owner refinanced to add an offset account, expecting to park rental income and build up a buffer. The offset-enabled loan came with a slightly higher rate, around 0.15% more than a basic variable product. Over the first 18 months, the average balance in the offset account sat below $5,000 because the rental income was being used for other expenses. The interest saved by the offset was less than the additional interest paid due to the higher rate. In that scenario, a basic variable loan with a lower rate and a separate savings account would have been the better structure.

A loan health check is a useful way to assess whether the features on your current loan are being used, or whether you're paying for functionality that no longer matches how you manage your finances.

Refinancing to Change Terms While Ignoring the Rate You're Leaving Behind

Some borrowers focus so heavily on changing the loan structure that they overlook whether the rate they're moving to is actually competitive. Refinancing to switch from a 25-year term to a 30-year term makes sense if the new rate is comparable or lower. It makes less sense if you're moving from a discounted rate to a higher one simply because your current lender won't adjust the term without refinancing internally, and you haven't compared what else is available.

This is common among Peninsula borrowers who've held their home loan with the same lender for several years. Their current rate may have drifted upwards as discounts expired, but because the focus is on adjusting the term or adding an offset, the rate comparison gets skipped. The refinancing process should address both the structural change and the rate at the same time, otherwise you risk improving one element while making the other worse.

Applying for a Refinance Without Reviewing Your Borrowing Capacity First

Lending criteria change, and your financial position may have shifted since you first took out your loan. Refinancing to change your loan terms still requires a full application, and if your income has dropped, your expenses have increased, or your credit profile has changed, you may not be approved for the same loan amount or structure you currently hold.

If you're refinancing to extend your loan term or increase your loan amount at the same time, your borrowing capacity becomes even more relevant. A borrower in Somerville who refinanced to access equity and extend the loan term found that their borrowing capacity had reduced due to changes in how lenders assess living expenses. The application was approved, but the loan amount was lower than expected, which meant the equity drawdown had to be reduced. Running a capacity assessment before submitting the refinance application would have identified the issue earlier and allowed time to adjust the structure or choose a different lender.

Refinancing to change your loan terms works when the structure aligns with how you're using the property and managing repayments. It stops working when the change is made without understanding the cost, the timing, or whether your circumstances still support the loan structure you're aiming for.
