Top tips to choose fixed, variable, or split loans

Which loan type suits first home buyers in Hornsby?

Your first home loan will likely be structured as fixed, variable, or a combination of both. A fixed rate locks your interest rate for a set period, typically one to five years, giving you predictable repayments. A variable rate moves with the market, meaning your repayment can rise or fall. A split loan divides your borrowing between fixed and variable portions, letting you hedge your position.

For buyers in Hornsby, where the median reflects a mix of established family homes in the lower North Shore catchment and newer apartments closer to the station, the loan structure you choose directly affects how much flexibility you have to repay faster or how protected you are if rates climb.

Consider a buyer who secures pre-approval for a unit near Hornsby Westfield with a 10% deposit. They have enough savings to cover the shortfall in borrowing capacity but want certainty around repayments while they settle into a new mortgage. Fixing the full loan amount at the time of settlement means their repayment stays the same for the fixed term, regardless of what happens with the Reserve Bank. But if they want to make extra repayments from a bonus or tax return, most fixed loans cap additional payments at $10,000 to $30,000 per year depending on the lender. Going over that limit triggers break costs, which can be substantial if rates have dropped since the loan was fixed.

How does a variable rate loan give you more control?

A variable rate loan adjusts when your lender changes their interest rate, which usually follows movements in the cash rate. When rates fall, your repayment drops. When they rise, so does your monthly cost. The advantage is flexibility. Most variable loans let you pay as much extra as you want without penalty, and many come with an offset account that reduces the interest you pay on the loan balance.

An offset account is a transaction account linked to your home loan. Every dollar in the offset reduces the balance on which interest is calculated. If you have a $500,000 loan and $20,000 sitting in offset, you only pay interest on $480,000. For first home buyers juggling upfront costs like stamp duty, conveyancing, and furniture, an offset gives you somewhere to park your savings without locking them away, while still cutting your interest bill each month.

Redraw is the other feature that appears on many variable loans. It lets you access extra repayments you have made above the minimum. Some lenders charge a fee to redraw, others set a minimum withdrawal amount, and a few place conditions on how often you can access it. Offset is generally more flexible because the money stays in your own account, whereas redraw requires you to pull funds back out of the loan.

What happens when you split your loan between fixed and variable?

A split loan divides your borrowing into two or more portions, each with its own rate type. You might fix 60% of the loan and leave 40% variable, or split it evenly. The fixed portion gives you repayment certainty on that part of the balance, while the variable portion gives you access to offset and unlimited extra repayments.

In our experience, buyers who expect their income to increase or who receive irregular income such as bonuses or commissions often prefer a split structure. It lets them lock in a baseline repayment while still having room to pay down debt faster when cash flow allows.

Say a buyer purchases a townhouse in Hornsby with a loan of $600,000 under the First Home Guarantee at a 5% deposit. They split the loan with $400,000 fixed for three years and $200,000 on a variable rate with offset. The fixed portion protects them if rates rise during that period, and the variable portion allows them to deposit their savings and any lump sums into the offset account, cutting interest on that $200,000 balance. If they receive a $15,000 tax refund or withdraw funds under the First Home Super Saver Scheme, they can place it straight into offset without worrying about break costs or annual caps.

The downside is that you are managing two loan accounts, sometimes with different repayment schedules depending on how your lender structures it. Some lenders allow a single repayment that splits automatically, others require separate payments. It is worth clarifying this during the application to avoid confusion once the loan settles.

When does fixing your rate make the most sense?

Fixing makes sense when you value certainty over flexibility, especially if your budget has little room for repayment increases. It also makes sense when you expect rates to rise and you want to lock in current pricing before that happens.

Buyers under the First Home Guarantee or the Regional First Home Buyer Guarantee often have tighter budgets because they are borrowing at 95% of the purchase price and covering upfront costs from genuine savings or gifted deposits. Locking the rate for two or three years gives those buyers breathing room to build up their offset balance or emergency fund without worrying about a rate shock in year one.

The risk is opportunity cost. If rates fall during your fixed period, you are still locked into the higher rate. And if you need to sell or refinance before the fixed term ends, break costs apply. These are calculated based on the difference between your fixed rate and the current wholesale rate your lender can get for the remaining term. The bigger the gap and the longer left on your fixed term, the higher the cost.

Another consideration is features. Most fixed loans do not come with offset, and extra repayment limits are common. If your circumstances change and you come into money you want to use to reduce the loan, you may not be able to without penalty.

How do interest rate discounts work across loan types?

Lenders offer different base rates and discount structures depending on whether the loan is fixed or variable, and the size of your deposit affects the rate you are offered. A borrower with a 20% deposit will generally receive better pricing than someone borrowing at 90% or 95%, even under the First Home Guarantee where Lenders Mortgage Insurance is waived.

Variable rates can be discounted further if you meet certain conditions such as making all repayments from a linked transaction account, holding other products with that lender, or borrowing above a certain threshold. Fixed rates are typically quoted as a flat rate for the term, with limited room to negotiate once the product is chosen.

When comparing loan options, focus on the comparison rate rather than the advertised rate. The comparison rate includes most fees and gives you a more accurate picture of the total cost over the life of the loan. It is especially relevant for first home buyers weighing up low-deposit options where application fees, valuation costs, and ongoing account fees add up quickly.

Does your loan structure affect how you use first home buyer concessions?

Your choice of fixed, variable, or split does not change your eligibility for stamp duty concessions or grants, but it does affect how you manage the deposit and settlement costs once you have accessed those benefits. In New South Wales, eligible first home buyers purchasing in Hornsby can access a stamp duty exemption on properties valued under $800,000 or a concession on properties between $800,000 and $1,000,000 under the First Home Buyers Assistance Scheme. That saving can free up several thousand dollars that would otherwise go to the state government.

If you are buying a new apartment or townhouse, the $10,000 First Home Owner Grant may also apply if the property is valued under $600,000, or under $750,000 for a house and land package. Stacking that grant with the First Home Guarantee reduces the cash you need upfront, but it also means you are borrowing closer to the full purchase price. In that scenario, having access to offset and redraw on at least part of your loan becomes more valuable because it gives you somewhere to direct any spare income and start reducing the principal as soon as possible.

Buyers using the First Home Super Saver Scheme to withdraw contributions from superannuation can also benefit from a variable or split structure. Once those funds are released, they can go straight into an offset account rather than sitting in a low-interest savings account, which keeps them accessible while cutting your interest cost from day one.
