Top tips to pick fixed rate features for first buyers

A fixed rate loan locks in your repayment amount for an agreed period, usually one to five years.

That predictability can feel steadying when you're rebuilding after a separation and managing a tighter budget. You'll know exactly what you owe each fortnight or month, which makes planning around other costs like legal fees or resettling expenses far more manageable. But not every fixed rate loan is built the same way, and some of the features you might assume are standard often aren't included at all.

Why fixed rate features matter when your finances are in transition

Features like extra repayment flexibility, portability, or the ability to make lump sum payments can all be restricted or removed entirely on a fixed rate loan. That might not matter much when life is stable, but when you're going through separation, circumstances shift quickly. A property settlement might land. You might receive a payout from a super split or the sale of a joint asset. If your loan doesn't let you pay down extra capital without penalty, you could be stuck paying interest on money you no longer need to borrow.

Consider someone refinancing after separation to buy out their former partner's share of the family home. They move to a fixed rate to lock in certainty around what they can afford each month. Six months later, they receive their share of a joint investment account and want to reduce the loan balance by $30,000. The loan permits up to $10,000 in additional repayments per year on the fixed portion without penalty, so they can put down $10,000 now and the rest either attracts a break fee or needs to wait until the fixed term ends. If they'd chosen a loan allowing $20,000 per year in extras, or one with no cap at all, they'd be in a different position.

How much extra repayment room do you actually need?

Most lenders cap additional repayments on fixed rate loans at somewhere between $10,000 and $30,000 per year without charging a break cost. Some permit unlimited extras. Others don't allow any additional repayments at all during the fixed term. Which structure works depends on whether you're likely to receive lump sums while the rate is locked.

If you're expecting a property settlement, inheritance, redundancy payout, or proceeds from selling another asset during the fixed period, a loan with higher or unlimited extra repayment capacity makes sense. If your income and expenses are stable and you're not anticipating windfalls, a lower cap or even no extra repayment feature might be acceptable in exchange for a slightly lower rate.

Fixed rate loans and offset accounts

Most fixed rate loans don't come with an offset account. Some lenders offer a partial offset on the fixed portion. Others let you split your loan so part is fixed without an offset and part is variable with full offset access.

An offset account can be valuable if you're managing irregular income, holding funds temporarily, or building a buffer after separation. Money sitting in the offset reduces the interest you're charged without being locked into the loan, so you keep full access to it. On a fixed rate loan without offset, any extra repayments you make usually go into a redraw facility instead, and redraw access can be restricted or removed by the lender at their discretion.

If keeping liquid savings accessible matters to you, either choose a fixed loan that includes offset or split your borrowing so the variable portion carries the offset and you park savings there.

Portability and what happens if you need to sell

Portability means you can take the loan with you if you sell the property and buy another one during the fixed term, without paying break costs. Not all lenders offer this feature. If they do, conditions usually apply. The new property might need to settle within a set window after the old one, and the loan amount often needs to stay the same or increase.

This matters if your living situation is still uncertain. You might be renting temporarily and planning to buy something more permanent once the divorce is finalised. Or you might be staying in the current home now but know you'll want to downsize or move closer to family within a year or two. If you lock into a fixed rate without portability and then need to sell, you'll likely face break costs, which can run into thousands of dollars depending on where rates have moved since you fixed.

Splitting your loan between fixed and variable

You're not required to fix the entire loan. Splitting lets you lock part of the borrowing for certainty and leave part variable for flexibility. A common approach is to fix 50% to 70% and leave the rest variable with an offset account attached.

In practice, this might look like fixing $250,000 at a set rate for three years and keeping $150,000 variable with offset access. Your repayments on the fixed portion stay the same regardless of rate changes. The variable portion gives you somewhere to park savings, make unlimited extra repayments, and access redraw without restriction. If rates drop, the variable portion benefits immediately. If they rise, the fixed portion shields you from part of the increase.

This structure suits people rebuilding after separation because it balances budget certainty with the ability to adapt as circumstances change. You can read more about low deposit loan structures if you're working with a smaller deposit after a property split.

What break costs actually are and when they apply

A break cost is a fee the lender charges if you exit a fixed rate loan early, make extra repayments beyond the allowed cap, or switch to a different loan product before the fixed term ends. The fee compensates the lender for the difference between the rate you're paying and the rate they can now lend that money out at.

If you fixed at 6.2% for three years and market rates have since fallen to 5.8%, the lender loses income by letting you out early. They calculate that loss and charge it to you. If rates have risen since you fixed, the break cost is usually zero because the lender isn't worse off.

Break costs are hardest to predict when you're uncertain whether you'll need to sell, refinance, or access equity during the fixed period. If there's a reasonable chance you'll need to do any of those things, either keep the fixed term short (one or two years instead of five), split the loan to limit your fixed exposure, or choose a product with portability and higher extra repayment limits.

Fixing during separation when one person is moving out

When one person is buying out the other and refinancing into their sole name, a fixed rate can provide stability while they adjust to covering the full mortgage alone. The risk is that the property settlement might not be finalised at the time they refinance, and terms could shift.

As an example, consider someone refinancing in their own name with the expectation they'll receive $80,000 from the sale of a jointly owned investment property within six months. They fix the full loan amount for three years to lock in repayments they know they can afford. The settlement is delayed and the $80,000 arrives 14 months later instead. By that point, they want to reduce the loan but the fixed rate loan only allows $10,000 per year in extras. They either pay the $80,000 into their offset on the variable split (if they have one), make the maximum $10,000 payment and hold the rest elsewhere, or pay a break cost to access the loan early.

If you're in this situation and the timing or amount of settlement funds is unclear, a split loan or a shorter fixed term reduces the chance you'll be locked in when you need flexibility. Getting pre-approval early in the separation process can help you structure the loan in a way that fits what's likely to happen, not just what's certain right now.

What to confirm before you lock in a rate

Before you commit to a fixed rate loan, confirm the following directly with your lender or broker: the maximum extra repayments allowed per year without penalty, whether an offset account is available and whether it's full or partial, whether portability is included and what conditions apply, how long the redraw process takes if you need access to extra payments you've made, and whether the loan allows you to split between fixed and variable or requires you to choose one or the other.

You should also ask what happens if you want to increase the loan during the fixed term, for example if you need to access equity for legal costs, relocation, or another purpose. Some lenders let you top up a fixed loan. Others require you to take out a separate variable loan for the additional amount.
