Fixed Rate Home Loans & What Not to Do When Locking In

A fixed rate home loan gives you a set interest rate for a defined period, typically one to five years.

For aged care nurses working rotating rosters or balancing permanent and agency shifts, that certainty matters when your income can vary month to month depending on whether you're picking up weekend penalties or taking on extra shifts during outbreak periods. Locking in a rate removes the risk of repayment increases during that fixed term, but it also removes flexibility if your circumstances change or rates drop.

Fixed Rate Home Loans: How the Structure Works

When you fix your rate, the lender calculates your repayments based on that agreed interest rate for the fixed period. Your repayments stay the same regardless of what happens to the official cash rate or variable rates during that time. At the end of the fixed term, your loan typically reverts to the lender's standard variable rate unless you negotiate a new fixed period or refinance.

Consider a nurse working in aged care who secures a three-year fixed rate and then receives a promotion to a Clinical Care Manager role with a stable roster and salary increase. If rates drop during the fixed period, she's still locked into the higher rate. If she wants to refinance to access a better rate or redraw equity for an investment property, she'll face break costs, which are calculated based on the lender's cost of unwinding the fixed rate contract. Those break costs can run into thousands of dollars depending on how much rates have moved and how much time remains on the fixed term.

What Not to Do: Fixing Your Entire Loan Amount

Fixing 100% of your loan removes all flexibility.

If you need to make extra repayments to reduce your debt faster, most fixed rate products cap additional repayments at $10,000 to $30,000 per year. Go beyond that and you'll pay break costs. If you need to access equity for a renovation, vehicle purchase, or second property, you'll either need to refinance and pay break costs or wait until the fixed period ends. For aged care nurses who might receive a redundancy payout, inheritance, or decide to sell and upgrade within a few years, that lack of flexibility can be costly. A split loan structure, where you fix a portion and leave the rest on a variable rate with an offset account, gives you rate certainty on part of the loan while maintaining access to redraw and offset benefits on the variable portion.

Offset Accounts and Fixed Rates: The Trade-Off

Most fixed rate home loans do not offer a linked offset account.

If you're an aged care nurse building savings between pay cycles or setting aside funds for planned leave, that's a significant limitation. Without an offset, your savings sit in a separate account earning minimal interest while your loan balance remains unchanged. On a variable rate loan with an offset, every dollar in the offset reduces the balance on which interest is calculated. In a scenario where you're saving $20,000 for a vehicle or overseas trip, that money could be offsetting your loan balance and reducing interest daily. On a fixed rate without offset, it's doing nothing for your loan. Some lenders offer fixed rates with offset functionality, but the rate is usually higher than a standard fixed rate, and you need to weigh whether the offset benefit justifies the rate premium.

Split Rate Loans: Balancing Certainty and Flexibility

A split loan divides your borrowing between fixed and variable portions.

You might fix 50% to 70% of your loan to lock in repayments on the majority of your debt, then keep the remainder on a variable rate with an offset account and unlimited additional repayments. This structure suits aged care nurses whose income includes a stable base salary plus variable penalty rates and overtime. The fixed portion covers your minimum repayment obligations, while the variable portion allows you to deposit surplus income into an offset or make extra repayments during high-earning periods without penalty. If rates rise, the fixed portion protects you. If rates fall, the variable portion benefits immediately, and you're not locked into an above-market rate across your entire loan. We regularly see this structure work for nurses managing irregular income or planning major purchases within a few years.

What Not to Do: Choosing a Fixed Term That Doesn't Match Your Plans

Locking in a five-year fixed rate when you're planning to sell or refinance within two to three years exposes you to unnecessary break costs.

If you're working in aged care and considering a move interstate for a senior role, or planning to upgrade from a unit to a house once you've built more equity, your loan structure needs to accommodate that timeline. Fixing for five years might give you a slightly lower rate than a two or three-year term, but if you need to exit early, the break costs can eliminate any interest savings. Before committing to a fixed term, consider where you expect to be in two, three, and five years. If there's a reasonable chance you'll sell, refinance, or need to access equity during that period, either fix for a shorter term or keep a larger portion of your loan on a variable rate. Your home loan pre-approval or refinance discussion should include a realistic assessment of your medium-term plans, not just the rate on offer today.

Portable Loans: Moving Your Fixed Rate to a New Property

Some lenders offer portable fixed rate loans, allowing you to transfer your existing fixed rate to a new property without break costs.

This feature is valuable if you're likely to sell and buy another property during the fixed period. However, portability usually comes with conditions: the new loan amount must be equal to or greater than the existing loan, the new property must meet the lender's security requirements, and you typically have a limited window (often 30 to 90 days) to settle on the new property. For aged care nurses who might relocate for work or upgrade as their family circumstances change, a portable loan provides flexibility without the penalty. Not all lenders offer this feature, and it's rarely advertised prominently, so it needs to be confirmed upfront during your application.

Fixed Rate Expiry: What Happens When the Term Ends

When your fixed rate term ends, your loan reverts to the lender's standard variable rate, which is typically higher than the discounted variable rates offered to new customers.

If you don't act before your fixed rate expiry, you could see your repayments increase significantly. Around three to six months before your fixed term ends, contact your broker or lender to negotiate a new rate or explore refinancing options. Lenders are often willing to offer existing customers a new fixed rate or a discounted variable rate to retain your business, but they won't do it automatically. For aged care nurses managing budgets around stable roster patterns, that reversion rate increase can disrupt your cash flow if you're not prepared. Set a reminder for six months before your fixed term expires and start the conversation early.

The Repayment Calculation and Interest Savings

Fixed rate loans are calculated on a principal and interest basis, meaning each repayment includes both interest charges and a reduction of your loan balance.

Because the rate is locked, your repayments are predictable, but the interest component gradually decreases and the principal component increases over time. If you're comparing a fixed rate to a variable rate, the decision comes down to whether you value repayment certainty over flexibility and the potential to benefit from rate cuts. Some aged care nurses prefer the certainty of knowing exactly what their repayments will be for the next few years, particularly if they're managing other financial commitments like vehicle loans or planning parental leave. Others prefer variable rates with offset accounts to maximise flexibility and take advantage of any rate reductions. Your choice depends on your income stability, savings habits, and short to medium-term plans.

Call one of our team or book an appointment at a time that works for you. We'll review your current income structure, deposit position, and plans over the next few years to determine whether a fixed rate, variable rate, or split structure aligns with your circumstances, and ensure you're not locking yourself into a product that limits your options down the track.
