Common Mistakes When Comparing Fixed Rate Loans

A fixed interest rate locks your repayments for a set period, usually between one and five years.

That predictability appeals to buyers in Baldivis who want certainty while they settle into a new home, but the decision carries more weight than most people realise. The rate you lock in today determines your repayments for years, and breaking that contract early can cost thousands. Choosing the wrong structure or term length creates problems that don't surface until you need flexibility.

Locking in Too Long Without Considering Your Timeline

Most lenders offer fixed terms from one to five years, but longer doesn't always mean safer.

Consider a buyer who fixes for five years at 5.8%, expecting stability. Three years in, they receive a job offer interstate and need to sell. The lender calculates break costs based on the difference between the fixed rate and current wholesale rates. If rates have dropped, the lender loses income for the remaining two years, and that loss gets passed to the borrower. In that scenario, break costs could reach $8,000 to $12,000, depending on the loan amount and rate movement. That expense often catches people off guard because the focus at application was on securing a low rate, not on what happens if circumstances change.

Baldivis has grown rapidly over the past decade, with new estates like Baldivis Central and the expansion around Shopping Centre Drive bringing younger families to the area. Many of those buyers are still early in their careers, and life can shift quickly. Fixing for three years instead of five gives you some certainty without locking you in through major life stages. If you know you'll need to upsize, relocate, or refinance within a few years, a shorter fixed term reduces the risk of paying break costs when you exit.

Choosing Fixed Over Variable Without Understanding the Trade-Off

A fixed rate home loan protects you from rate rises, but it also removes flexibility.

Most fixed rate products don't allow extra repayments beyond a small annual limit, often capped at $10,000 to $20,000 per year. If you receive a bonus, inheritance, or tax refund, you can't use that money to reduce your loan balance without triggering break costs. You also lose access to features like a linked offset account, which means any savings sit in a transaction account earning minimal interest instead of offsetting your loan.

A split loan structure gives you both. You might fix 60% of your loan amount at a set rate and leave 40% on a variable rate with an offset account attached. The fixed portion gives you predictable repayments, while the variable portion lets you make extra payments and use an offset to reduce interest. That approach works well for buyers who want certainty but also expect to have surplus income they can direct toward the loan. It's not the right fit for everyone, but it's worth considering before you commit the entire loan amount to a fixed rate.

Ignoring the Comparison Rate When Comparing Fixed Rate Loans

The advertised interest rate is what gets attention, but the comparison rate tells you what the loan actually costs.

The comparison rate includes the interest rate plus fees like application fees, ongoing monthly fees, and other charges spread across a standard loan amount over 25 years. A lender might advertise a fixed rate of 5.6%, but if they charge a $600 application fee and a $15 monthly fee, the comparison rate could be 5.75%. Another lender with a 5.65% fixed rate and no ongoing fees might have a comparison rate of 5.68%. The second option costs less over time, even though the headline rate looks higher.

When you're comparing home loan rates, look at both figures. The comparison rate gives you a clearer picture of what you'll actually pay, especially if you're comparing products from different lenders with different fee structures. That said, the comparison rate is based on a standard loan amount and term, so if your situation differs significantly, the actual cost might vary. It's a useful guide, not a guarantee.

Fixing the Entire Loan Amount Without Leaving Room for Life

Fixing your entire loan amount can feel like the safest choice, but it removes every option to adapt.

In a scenario like this: a couple buys in Baldivis and fixes their entire loan at 5.7% for four years. Eighteen months later, they have their second child and one partner reduces their work hours. Their income drops, and they need lower repayments. On a variable rate loan, they could extend the loan term or switch to interest only for a period to reduce repayments. On a fully fixed loan, they can't. They're locked into the same repayment amount until the fixed term ends, and if they can't meet those repayments, they risk default.

This doesn't mean you shouldn't fix. It means you should think about how much of your loan to fix. Fixing 50% to 70% gives you stability on the bulk of your loan while leaving a portion on variable that you can adjust if your circumstances change. You can extend the term on the variable portion, make extra payments, or switch to interest only without touching the fixed portion. That flexibility matters when life doesn't go to plan.

Assuming All Fixed Rate Home Loan Products Are the Same

Not all fixed rate loans are structured the same way, and the differences matter once you're in the loan.

Some lenders allow small extra repayments on a fixed rate loan, others don't allow any. Some products are portable, meaning you can take the loan with you if you sell and buy another property without breaking the fixed term. Others aren't, so selling triggers break costs regardless of whether you're staying with the same lender. Some lenders calculate break costs differently, using a formula that can result in a higher or lower exit cost depending on rate movements.

These details aren't always clear in the product disclosure statement, and they're rarely highlighted during the application process. You need to ask specific questions: Can I make extra repayments? Is the loan portable? How are break costs calculated? What happens if I need to refinance before the fixed term ends? The answers shape how the loan behaves over time, and they're worth understanding before you apply for a home loan.

Focusing Only on the Interest Rate and Ignoring the Loan Features

The interest rate affects your repayments, but the loan features affect how the loan works for you over time.

A fixed rate loan with no offset, no extra repayments, and high break costs might have a slightly lower rate than a competitor, but it leaves you with no flexibility. If you're buying an owner occupied home in Baldivis and planning to stay for the long term, that might not matter. But if there's any chance you'll need to sell, refinance, or adjust your repayments, the features matter more than a 0.1% difference in the rate.

Look at what the loan lets you do, not just what it costs. Can you make extra repayments? Can you link an offset account to the variable portion of a split loan? Can you take the loan with you if you move? Those features don't always show up in a rates comparison table, but they determine whether the loan supports your goals or gets in the way.

Not Reviewing Your Home Loan When the Fixed Term Ends

When your fixed term ends, your loan automatically rolls onto the lender's standard variable rate, which is usually higher than the rate you could get by refinancing or renegotiating.

Most lenders send a notification 30 to 60 days before your fixed term expires, but many borrowers don't act on it. They assume the transition is automatic and that their rate will be reasonable. It's not. The standard variable rate is often 1% to 2% higher than the discounted variable rate offered to new customers. On a loan amount of $400,000, that's an extra $4,000 to $8,000 per year in interest.

Before your fixed term ends, compare what your lender is offering against what's available in the market. If your circumstances have changed, your borrowing capacity might have improved, which could qualify you for a lower rate or additional features. Refinancing takes time, so start the process at least 90 days before your fixed term expires. If you wait until after it ends, you're already on the higher rate, and you'll pay more while the refinance processes.

If your fixed rate is ending soon and you're not sure what to do next, a fixed rate expiry review can clarify your options before you roll onto a higher rate.
