What are Fixed Rate Loans and Extra Repayments for First Home Buyers?

Most fixed rate loans let you make extra repayments up to a set limit each year without penalty, but go over that cap and you could pay thousands in break costs.

If you're buying your first home in Maroochydore and weighing up whether to fix your rate, the extra repayment rules matter more than you might think. Lock in too much of your loan and you could lose the flexibility to pay down debt faster when you have spare cash. Lock in too little and you might miss out on rate certainty during a period when every dollar counts.

Fixed Rate Loans Still Allow Extra Repayments Within Limits

A fixed rate loan holds your interest rate steady for a set term, usually between one and five years. Most lenders allow you to make extra repayments up to a certain amount each year without triggering break costs, typically between $10,000 and $30,000 depending on the lender and loan size.

Consider a buyer who secures a fixed rate loan on a unit near the Maroochydore CBD. They receive a work bonus six months after settlement and want to put $15,000 straight onto the mortgage. If their lender's cap is $20,000 per year, the payment goes through without penalty. If the cap is $10,000, they pay $5,000 over the limit and may be charged a break cost calculated on the difference between the fixed rate and the current market rate for the remaining fixed term.

What Happens When You Exceed the Extra Repayment Cap

Break costs apply when you repay more than the allowed annual limit or when you refinance, sell, or fully repay a fixed rate loan before the term ends. The lender calculates the economic loss it incurs by using a formula that compares your fixed rate to the rate it can now lend that money at. If rates have fallen since you fixed, the break cost can be substantial. If rates have risen, the break cost is usually nil.

We regularly see first home buyers surprised by this. They assume a fixed rate loan works the same as a variable rate loan where you can pay as much as you want, whenever you want. The fixed term provides certainty, but it comes with conditions.

Split Loans Give You Rate Certainty and Flexibility

A split loan divides your borrowing into two portions: one fixed, one variable. You might fix 50% or 60% of the loan to protect against rate rises and leave the rest on a variable rate so you can make unlimited extra repayments, access a redraw facility, or link an offset account.

In a scenario like this, a Maroochydore buyer purchasing near Cotton Tree borrows at the suburb's current median. They fix 60% of the loan for three years and keep 40% variable. The fixed portion gives them predictable repayments while they settle into homeownership. The variable portion lets them deposit rental income from a boarder, tax refunds, or savings without restriction. Those extra payments reduce the loan balance and the interest charged on the variable portion immediately.

First home buyers using a 5% deposit under the Australian Government scheme can structure a split loan just like any other borrower, provided the lender offers it within their participating product range.

Offset Accounts Usually Don't Work on Fixed Rate Loans

Most fixed rate loans do not allow you to link an offset account. An offset account is a transaction account where the balance offsets the interest charged on your home loan. If you have $20,000 sitting in an offset and a $400,000 loan, you only pay interest on $380,000.

Variable rate loans typically include offset accounts. Fixed rate loans rarely do. If having an offset matters to you, particularly if you expect irregular income or want to park savings while keeping them accessible, you'll need to either keep your loan variable or use a split structure where the variable portion has the offset attached.

This distinction matters for buyers in Maroochydore who work casually, run a business, or have seasonal income patterns common in the hospitality and tourism sectors around the Sunshine Plaza and Ocean Street precinct.

Redraw Facilities on Fixed Rate Loans Are Often Restricted

A redraw facility lets you withdraw extra repayments you've made on your loan. On a variable rate loan, redraw is usually available at any time with no fee or a small processing charge. On a fixed rate loan, redraw may be unavailable entirely, restricted to a certain number of withdrawals per year, or subject to higher fees.

Some lenders allow redraw on fixed loans but count any withdrawal as part of your annual extra repayment cap. If you've already made $20,000 in extra payments during the year and your cap is $20,000, you won't be able to redraw any of it without incurring break costs in that same year.

Before committing to a fixed rate loan, confirm how redraw works with that specific lender. Don't assume it operates the same way as the variable product.

When Fixed Rates Make Sense for First Home Buyers

Fixing part or all of your home loan can be useful if you want certainty around repayments, particularly in the first few years of ownership when your budget is tight and your savings buffer is still building. If you're stretching to afford the repayments at current variable rates, a fixed rate can remove the risk of repayment shock if rates rise.

Fixed rates are less useful if you expect to make large lump sum repayments, if you plan to sell or refinance within the fixed term, or if you want ongoing access to features like offset accounts and unlimited redraws. In our experience, buyers who prioritise flexibility over certainty tend to keep more of their loan variable or use a split with a smaller fixed portion.

How the 5% Deposit Scheme Works With Fixed and Variable Rates

The Australian Government 5% Deposit Scheme allows eligible first home buyers to purchase with a 5% deposit without paying lenders mortgage insurance. You can use the scheme with a fixed rate loan, a variable rate loan, or a split loan, depending on what the participating lender offers.

Not all participating lenders provide the same loan features. Some offer offset accounts on variable loans but not on fixed. Some allow splits, others don't. Some set higher extra repayment caps on fixed loans than others. You need to compare what's available within the panel of participating lenders, not just assume every option works the same way.

Property price caps under the scheme are $1,000,000 for Queensland regional centres including Maroochydore and $700,000 for other areas of Queensland. Both the purchase price and the lender's valuation must sit at or below the cap.

Buyers using a 10% deposit outside the scheme have access to a wider range of lenders and sometimes more flexible loan features. Whether the trade-off between saving a larger deposit and accessing more product choice is worth it depends on how long it would take you to save the extra 5%, what the property market is doing in that time frame, and what loan features matter most to you.

Stamp Duty Concessions in Queensland Still Apply With Fixed Loans

Queensland first home buyers purchasing an established home can access a transfer duty concession that reduces stamp duty by up to $17,350 on properties valued under $710,000, with the concession phasing out completely at $800,000. Buyers purchasing a new home or vacant land can access a full transfer duty concession with no price cap.

The $30,000 first home owner grant applies to new homes valued under $750,000 and has been extended for four years from 1 July 2026. The grant does not apply to established homes.

These concessions work the same way regardless of whether you choose a fixed rate loan, a variable rate loan, or a split. The loan structure you pick has no impact on your eligibility for state-based support. You will need to meet residency requirements, which typically mean moving into the property within 12 months of settlement and living there as your main home for at least 12 continuous months.

Making the Call Between Fixed, Variable, and Split

Start by working out how much spare cash you expect to have over the next few years. If you're likely to have lump sums from bonuses, tax returns, or family gifts, keeping more of your loan variable or using a split gives you somewhere to put that money where it works hardest.

If your income is stable but tight, and you want to know exactly what your repayments will be while you adjust to ownership costs like rates, insurance, and maintenance, fixing a larger portion can provide breathing room.

There is no single right answer. The loan structure that suits a dual-income couple with steady salaries buying in Maroochydore's established unit market will look different to a single buyer on casual hours purchasing a townhouse near the hospital precinct. Your circumstances, your risk tolerance, and your financial goals decide the structure, not a one-size-fits-all rule.
