How to Use a Variable Loan and Extra Repayments Well

A variable rate loan lets you pay extra whenever you can, and that flexibility is the main reason many first home buyers choose it. KM Financial Service is an award-winning mortgage broking team that has helped local families buy in Austral and across South West Sydney, and we see the same question often: how much should I pay on top of the minimum?

This guide is for a first home buyer deciding between a variable and a fixed loan, and working out how extra repayments, an offset account or redraw fit around the purchase.

What Is a Variable Rate Loan for a First Home Buyer?

A variable rate loan has an interest rate your lender can change over time, so your minimum repayment can rise or fall. Most lenders allow extra repayments on a variable loan, while a fixed interest rate loan often limits how much extra you can pay without a fee. Check the terms with your lender.

The trade-off is certainty. If your lender raises the rate, your repayment goes up, and you cannot lock in a figure the way you can with fixed. A fixed loan gives stable repayments, but it can restrict extra payments and may carry break costs if you exit early. Our fixed rate expiry page explains what happens when a fixed term ends. Some buyers split the loan, with part fixed and part variable, which gives some certainty and some flexibility.

Offset Account or Redraw: Which Suits Your Extra Repayments?

An offset account is a transaction account linked to your loan, and the balance in it reduces the loan amount that interest is charged on. Redraw lets you pay extra into the loan itself and withdraw it later, if your lender allows.

Both cut the interest charged on your loan, but they work differently day to day. With an offset, your money stays in an everyday account you can use freely. With redraw, access depends on your lender's rules, and some set minimum withdrawal amounts, processing times or limits. The cost to weigh up: loans with an offset account may carry an annual package fee or a higher rate, depending on the lender. If you plan to keep only a small balance in the account, that fee may outweigh the benefit.

How Extra Repayments Work in Practice: An Example

Extra repayments shrink your loan balance faster, and the habit also gives you a buffer if your repayments rise. As an example, consider a first home buyer who borrows $600,000 over 30 years. At an illustrative rate of 6.75% p.a., the minimum repayment is about $3,892 a month.

The buyer sets up a $200 monthly extra payment into the loan, taking the total to about $4,092. Over twelve months that is $2,400 of extra principal, which stops attracting interest. They also keep a few thousand dollars in redraw for emergencies, so the extra money is not locked away. If the lender later lifts the rate and the minimum repayment rises, the buyer is already used to paying more than the minimum. They can pause the extra $200 without changing their budget. Use a repayment calculator with your own loan size to see how different extra amounts affect your balance.

Austral First Home Buyer: Stamp Duty and Deposit Schemes That Shape Your Loan

In New South Wales, a first home buyer pays no transfer duty on a home valued at $800,000 or less, for contracts exchanged on or after 1 July 2023. A reduced rate applies above that value, up to a home valued below $1,000,000, and no concession applies from $1,000,000. To qualify, you generally need to move in within 12 months of settlement and live there for at least 12 continuous months. Your solicitor or conveyancer lodges the claim.

AusTral is in the Liverpool local government area, and HtAG data describes it as an almost entirely house market, so most buyers here are comparing houses against these thresholds. If you are building or buying new, the NSW First Home Owner Grant is $10,000 for a new home priced at $600,000 or less. For vacant land plus a building contract, the total must be $750,000 or less.

If your deposit is small, the Australian Government 5% Deposit Scheme lets eligible first home buyers buy with a 5% deposit without paying Lenders Mortgage Insurance (LMI). It operates through participating lenders only, and the price cap for a property depends on its suburb and postcode in Housing Australia's search tool. The published materials do not say which loan features, such as an offset account, come with the scheme, so confirm that with the participating lender before you commit. The trade-off of a low deposit is a larger loan and larger repayments.

Pre-Approval and Borrowing Capacity Before You Choose a Loan Structure

Pre-approval shows what a lender is likely to let you borrow, and it should be set at a level you can still afford if your interest rate rises. Lenders assess your income, expenses and debts, so two buyers on the same income can get different results. Our borrowing capacity page explains the factors involved.

Build your budget around the repayment you could manage if the rate moved up, not the lowest repayment on offer today. Then decide how much of your spare cash goes into extra repayments, and how much stays in your offset or redraw as a safety cushion. Our first home buyers page covers the wider purchase process, and our Austral home loans page is the place to start if you are buying locally.

Every buyer's position is different, so the right mix of variable, fixed, offset and redraw depends on your income, your deposit and how steady your work is. Call one of our team or book an appointment at a time that works for you, and we will set up a loan structure around your goals.
