First Home Buyers and Fixed Rate Loan Terms Explained

A fixed rate locks in your repayment for a set period, and that certainty comes with limits on how flexibly you can pay the loan down.

For a Melbourne first home buyer working to a tight budget, that trade-off is the heart of the decision. Fixing can make early budgeting calmer. It can also restrict extra repayments and cost you money if you sell or refinance before the term ends.

How Does a Fixed Rate Home Loan Work?

A fixed rate home loan holds your interest rate at one level for a set term, commonly one to five years, so your repayment will not change during that period. When the term ends, the loan usually moves to the lender's variable rate unless you choose a new fixed term.

The appeal for a first home buyer is predictability. You know your repayment from day one, which makes a first home buyer budget easier to plan around. The trade-off is that you will not benefit if rates fall, and many lenders limit extra repayments during the fixed period. Many fixed loans also do not come with an offset account or full redraw access, though this varies by lender.

When you apply, the lender assesses your borrowing capacity, and it is worth checking yours early using our borrowing capacity page.

Fixed or Variable Interest Rate: Which Suits a First Home Buyer?

A fixed rate suits buyers who value certainty over flexibility, while a variable rate suits those who want to make extra repayments or use an offset account. Neither is better for everyone, and the choice depends on your savings pattern and how settled your plans are.

A variable rate moves with the lender's decisions, so repayments can rise or fall. In return, variable loans often allow unlimited extra repayments and can include an offset account, which reduces the interest charged on your balance. If you expect a bonus, a pay rise or a partner returning to work, that flexibility may be worth more than certainty.

What Does a Fixed Rate Repayment Look Like?

On an illustrative rate of 6.75% p.a., a $600,000 loan over 30 years has a monthly principal and interest repayment of about $3,891. This figure is an example only, and your actual rate will depend on your deposit size and lender.

Consider a first home buyer couple who fix that $600,000 loan for three years at the illustrative 6.75% p.a. Their repayment stays at about $3,891 a month for the whole fixed term, which lets them set a firm household budget. After three years the loan reverts to the lender's variable rate, so the repayment may change. If they stay in the home and their plans hold, the fixed term does what they wanted: stable repayments while they settle in.

If they instead needed to sell in year two, they could face break costs, which are covered next. You can test different loan sizes and extra repayments with our extra repayment calculator.

Fixed Rate Break Costs: What Happens If You Exit Early?

If you repay or refinance a fixed loan before the term ends, the lender may charge a break cost. The amount depends on the rate movement since you fixed, the balance and the time remaining, so it can be small or substantial.

Break costs matter because first home buyers often change plans sooner than expected. A job move, a growing family or a relationship change can all lead to selling early. Ask your broker for a written explanation of how your chosen lender calculates break costs before you commit. If a fixed term is nearing its end, our fixed rate expiry page explains your choices.

Splitting Your Loan: Part Fixed, Part Variable

A split loan fixes one portion of your debt and leaves the rest variable, giving you some certainty and some flexibility. The cost is that you carry two rates and the fixed portion still has the usual restrictions.

Consider a buyer with a $600,000 loan who fixes $400,000 for two years and keeps $200,000 variable with an offset account. The fixed portion covers most of the repayment risk, while the variable portion lets them park savings in the offset account or make extra repayments without penalty. If rates rise, only the variable part moves. If they sell early, break costs apply only to the fixed portion, which limits the exposure. The downside is that the fixed portion still cannot be paid down freely, and the offset benefit applies only to the variable side.

Whether this structure works depends on lender policy, so it is worth discussing with a broker before you apply for a home loan.

Combining a Fixed Loan With First Home Buyer Support

The Australian Government 5% Deposit Scheme lets eligible first home buyers purchase with a 5% deposit without paying LMI, and applications go through a participating lender. Housing Australia's published materials do not state whether fixed rates or offset accounts are available under the scheme, so confirm this with the lender before you plan around it.

In Victoria, the 5% Deposit Scheme price cap is $950,000 for the capital city and regional centres category and $650,000 for other areas, and the cap for a specific property depends on its postcode. For Victorian first home buyer stamp duty concessions, no land transfer duty is payable on a dutiable value up to $600,000, with a concession up to $750,000. You can estimate your own bill using our stamp duty calculator, and learn more on our first home buyers page.

A smaller deposit can also mean LMI unless a scheme or waiver applies, so check our LMI waivers page.
