Why Should First Home Buyers Consider a Variable Loan?

A variable rate home loan gives you room to move, and the features attached to it matter as much as the rate itself. If you are buying your first home in Sutherland, this guide shows which features are worth asking about and what each one costs you.

What Is a Variable Interest Rate Home Loan?

A variable interest rate home loan is a loan where your lender can change the rate over time, so your repayments can go up or down. Lenders often respond to movements in the RBA cash rate, but each lender makes its own call on timing and size.

The trade-off is certainty. A fixed interest rate locks in your repayment for a set period, while a variable loan can cost more if rates rise. In return, variable loans often come with extra features that suit people who expect their finances to grow, such as a pay rise or a partner returning to full-time work. You can browse the range on our home loans page.

Which Variable Rate Features Matter Most for a First Home Buyer?

The features that matter most are an offset account, redraw and the ability to make extra repayments. Each one helps you reduce the interest you pay, but each has a catch.

An offset account is a transaction account linked to your loan. The balance is subtracted from your loan when interest is calculated, so the more you keep there, the less interest you are charged. The catch is that some loans with an offset account carry an annual fee or a higher rate, so it only pays off if you keep a decent balance in it.

Redraw lets you take back money you have paid ahead of schedule. It is handy as a safety net, though lenders can set limits on how much you withdraw or how quickly, so check the rules before you rely on it.

Extra repayments are the third lever. Paying a little more each month shortens your loan, but only if you can keep it up without leaving yourself short for bills.

How an Offset Account Works: A First Home Buyer Example

Consider a couple buying their first home who borrow $500,000. Using an illustrative rate of 6.75% p.a. over 30 years, their repayment is about $3,243 a month. This is an example only, and your own rate will depend on your lender and your deposit.

They have $20,000 in savings and worry about locking it away. Instead of putting it into the loan, they keep it in an offset account. Interest is now charged on $480,000, not $500,000. At the illustrative rate, that trims roughly $112.50 off the first month's interest, and the savings stay available if the hot water system dies.

Then they test a rate rise. If the rate moved up by 0.25 percentage points to 7.00% p.a., the same loan would cost about $3,327 a month, roughly $84 more. Because their savings sit in the offset account, they can see the cushion clearly and plan for it. The outcome is a loan that costs less in interest, keeps cash accessible and shows how a small rate rise would affect repayments. Lenders assess serviceability at a rate at least 3 percentage points above the loan rate, so budget for larger rises than this. The trade-off is that the offset only works while the money stays in there, and any offset fee reduces the benefit. A calculator on your lender's site can show the numbers for your own situation.

Can You Get a Variable Loan with a 5% Deposit and Stamp Duty Concessions?

State stamp duty concessions can generally be used alongside the Australian Government 5% Deposit Scheme, as long as you meet each scheme's rules. The loan features and the schemes are separate questions, so check both.

Under the Australian Government 5% Deposit Scheme, eligible first home buyers can buy with a 5% deposit, and Housing Australia backs the lender so no Lenders Mortgage Insurance (LMI) is payable. Applications go through a participating lender, and the home must be under a price cap that depends on its suburb and postcode. You also need to live in the home. If you move in late or move out early, the lender may ask you to pay LMI. Housing Australia does not state which loan features, including variable rates, are available under the scheme, so confirm with the participating lender whether a variable rate, an offset account or redraw is available on your loan.

On the New South Wales side, for contracts exchanged on or after 1 July 2023, the First Home Buyers Assistance Scheme exempts homes valued at $800,000 or less from transfer duty. Homes above $800,000 and below $1,000,000 receive a reduced rate. Your solicitor or conveyancer lodges the claim, and you need to move in within 12 months of settlement and live there for at least 12 continuous months.

Why Get Pre-Approval Before You Choose Features?

Pre-approval shows you how much a lender is willing to lend, which helps you decide which features are realistic for your budget. It lets you shop with a clear ceiling rather than a guess.

It also gives you time to compare lenders on more than the headline rate. Two loans with the same rate can differ in fees, offset rules and redraw limits. Our borrowing capacity page explains how lenders look at your income and spending, and our first home buyers page walks through the journey from saving to settlement. If you live locally, our Sutherland broker page shows how we work with people nearby.

Pre-approval is not a final offer, and the lender will still check the property and your situation before settlement. Even so, it is a strong starting point for talking to agents and sellers with confidence.

If you would like to talk through variable rate features at your own pace, call one of our team or book an appointment at a time that works for you through our booking page. We will compare lenders for you, explain the costs in plain language and help you choose a loan that fits where you are heading.
