When to Switch Your Home Loan Repayment Strategy

Your repayment strategy should change as your income and roster patterns change.

Many nurses stay with the same repayment approach they set up at settlement, even after their base rate increases, they pick up extra shifts, or their household circumstances shift. That means they miss opportunities to build equity faster or protect themselves when rosters tighten. The right repayment structure for a graduate nurse working rotating shifts is different from what works for a nurse practitioner with consistent hours or someone reducing to part-time before a planned secondment.

Principal and Interest Repayments When Income Stabilises

Principal and interest repayments reduce what you owe with every payment and should be your default once your income becomes predictable.

Consider a registered nurse who started on a variable rate loan with minimum repayments during their first year, while still adjusting to shift work and overtime availability. Once their roster settled and their base rate increased after twelve months, they switched to paying an extra $200 per fortnight above the minimum. That additional amount went straight to the principal, reducing the loan term and the total interest paid over the life of the loan. The earlier you make these additional payments, the more impact they have, because you reduce the balance on which interest compounds.

If you are working consistent hours and your income supports it, directing extra repayments to an owner occupied home loan will build equity faster than keeping surplus cash in a standard savings account. The interest you save by reducing your loan balance will almost always exceed the interest you earn elsewhere.

Offset Accounts for Nurses with Variable Income

An offset account gives you the interest savings of paying down your loan while keeping your cash available.

This works well if your income fluctuates due to casual shifts, agency work, or periods of unpaid leave. The balance in your offset account reduces the amount of your loan that accrues interest, so a $15,000 offset balance on a $400,000 loan means you only pay interest on $385,000. Unlike making extra repayments directly to the loan, the money in the offset remains accessible. If your roster is cut or you take parental leave, that buffer is still yours to draw on without needing to reapply for credit.

In our experience, nurses who work a mix of permanent part-time and agency shifts benefit most from this structure. They can deposit their higher-earning months into the offset and withdraw during quieter periods without affecting the loan itself. Some lenders charge a slightly higher interest rate for loans with a full offset feature, so compare whether the flexibility justifies the cost based on how variable your income actually is.

Interest Only Periods for Investment Properties

Interest only repayments can improve cash flow on an investment loan, but they do not reduce what you owe.

If you hold an investment property and the rent covers most of the interest, switching to interest only frees up cash that you can redirect to paying down your owner occupied loan or building a deposit for another property. The interest on an investment loan is typically tax deductible, so there is less urgency to pay down that principal compared to your own home. Interest only periods usually last between one and five years, depending on the lender, and you will need to demonstrate that you can still afford the principal and interest repayments once the interest only term ends.

This approach does not suit your primary residence in most cases. Without paying down the principal, you are not building equity, and you will pay more interest over the life of the loan. The exception might be a short-term situation where you need to reduce repayments temporarily due to reduced hours or a planned career break, but even then, an offset account or redraw facility often provides more flexibility without extending your loan term.

Fixed Rate Repayment Locks When Rates Are Rising

Fixing part or all of your loan can protect your repayment amount if you need certainty over your budget.

When variable interest rates are climbing or expected to rise, locking in a fixed rate means your repayments will not change for the fixed period, which can range from one to five years. This suits nurses who have stretched their borrowing capacity and cannot absorb rate increases without cutting into essential expenses. The downside is that most fixed rate products limit or prevent additional repayments, and if you break the fixed term early due to selling or refinancing, you may face break costs that run into the thousands.

A split loan structure can give you some of both. You might fix 50% of your loan to protect your minimum repayment and leave the other 50% variable so you can make extra repayments when your income allows. That way, you have budget certainty without losing all flexibility. If you are considering this, the decision should be made before rates move, not after. Once fixed rates have already increased, the benefit is reduced.

Switching to Fortnightly Repayments to Reduce Interest

Paying fortnightly instead of monthly results in one extra month's repayment each year and cuts your loan term.

Most people are paid fortnightly, so aligning your loan repayment with your pay cycle makes budgeting more straightforward. Because there are 26 fortnights in a year but only 12 months, paying half your monthly repayment every fortnight means you make 13 monthly repayments instead of 12. That extra repayment reduces your principal faster and can shave years off a 30-year loan without requiring you to find additional funds. The structure also reduces the average daily balance your interest is calculated on, which compounds the savings.

You can usually switch to fortnightly repayments by contacting your lender directly or adjusting your payment schedule online. There is no cost to make the change, and it does not require a formal loan variation. If your lender does not support true fortnightly repayments and instead splits your monthly amount in two without the additional repayment benefit, consider whether refinancing to a lender who does might be worthwhile, especially if you are also reviewing your interest rate.

Redirecting Repayments After Paying Off Investment Debt

Once an investment loan is paid off, redirecting those repayments to your owner occupied loan accelerates equity in your primary residence.

If you have been managing both an owner occupied home loan and an investment loan, the investment loan will often have a lower balance or a shorter remaining term, particularly if you have been making additional repayments or benefited from rental income. Once that investment loan is cleared, you have the option to redirect what you were paying on that loan toward your own home. Because the interest on your owner occupied loan is not tax deductible, paying it down faster has a greater after-tax benefit than keeping cash in other savings vehicles.

This approach also improves your borrowing capacity if you are planning to expand your portfolio again. Lenders assess your serviceability based on your existing debt commitments, so eliminating one loan increases how much they will lend you for the next purchase. If your goal is to build a property portfolio over time, clearing smaller debts strategically and reallocating repayments gives you more control over timing and leverage.
