Top Tips to Pair Fixed Rates and Offset Accounts

The loan structure you pick matters as much as the rate you are quoted. For a first home buyer in Gregory Hills, the real question is how much certainty you want and how much flexibility you are prepared to give up for it.

At KM Financial Service, we are an award-winning team that works with local families every week. Fixed rates and offset accounts are two of the most common features we compare for first home buyers, and they do not always sit together in the one loan.

How Does a Fixed Rate Home Loan Work for a First Home Buyer?

A fixed rate home loan locks your interest rate and repayment for an agreed period, so your repayment will not change during that time. A variable interest rate can move up or down at the lender's discretion.

The trade-off is flexibility. Depending on the lender, a fixed loan may limit extra repayments, may not come with an offset account, and may carry break costs if you refinance or sell before the fixed term ends. Fixed certainty suits a buyer whose budget is tight and who would struggle if repayments rose. It suits less if you expect to make large extra repayments soon.

When the fixed period finishes, your loan moves to a different rate unless you act. Our fixed rate expiry page explains what to check before that date arrives.

How Does an Offset Account Work on a Home Loan?

An offset account is a transaction account linked to your home loan, and the balance in it reduces the amount your lender charges interest on. Your savings stay accessible, unlike extra payments into a loan.

Consider a first home buyer with a $600,000 loan over 30 years. At an illustrative rate of 6.75% p.a., the repayment is about $3,892 a month on principal and interest. Interest in the first month is about $3,375. If they keep $30,000 of savings in the offset account, interest is charged on $570,000 instead, which is about $3,206 for that month. That is roughly $169 less interest, and it happens every month while the balance stays there.

The outcome is that the buyer's repayment can stay the same while more of it goes to the loan balance. The trade-off is that some lenders charge a package or annual fee for loans with an offset account, and the benefit only works if you actually keep money in it. A redraw facility is a different feature. It lets you take back extra repayments you have made, but lenders set their own rules and may limit access.

Can You Have a Fixed Rate and an Offset Account Together?

Sometimes, but it depends on the lender and the product. Some lenders do not attach an offset account to a fixed loan, so many borrowers split the loan instead.

In a split loan, one portion is fixed and the other is variable with an offset account attached. A buyer might fix a larger portion for repayment certainty and keep a smaller variable portion where their savings can sit. The cost is that you manage two balances, and only the variable portion benefits from the offset. If your savings are larger than that variable balance, the extra savings do not reduce interest.

Before you choose a split, ask the lender three direct questions. Is an offset account available on the fixed portion? What is the cap on extra repayments? What are the break costs if you leave early? Our home loans team can compare these answers across lenders for you, and the borrowing capacity page is a good starting point for working out what you can afford.

Does the 5% Deposit Scheme Change Your Loan Features?

The Australian Government 5% Deposit Scheme lets eligible first home buyers buy with a 5% deposit without paying lenders mortgage insurance. Housing Australia backs the lender for the part of the loan between the deposit and 20% of the property value.

Loan features such as fixed rates and offset accounts depend on the participating lender and product, so confirm what is available with that lender before you commit. Applications go only through a participating lender, and there is a price cap that depends on the property's suburb and postcode in Housing Australia's postcode search tool. For New South Wales, the cap for the capital city and regional centres category is $1,500,000, but check the exact figure for Gregory Hills before you make an offer. A broker can also check this for you.

Which First Home Buyer Grants and Stamp Duty Concessions Affect Your Budget?

In New South Wales, first home buyer stamp duty concessions can reduce or remove transfer duty, and the first home owner grant of $10,000 applies only to new homes. These savings change how much cash you have left for a deposit or an offset balance.

For contracts exchanged on or after 1 July 2023, homes valued at $800,000 or less are exempt from transfer duty. Homes valued above $800,000 and below $1,000,000 receive a reduced rate, and no concession applies from $1,000,000. The $10,000 grant applies to a new home with a purchase price of $600,000 or less, or to vacant land plus a building contract valued at $750,000 or less. You must also move in within 12 months and live there for at least 12 continuous months. Our first home buyers page covers the wider process, and these rules can change, so confirm them with Revenue NSW or your solicitor or conveyancer.

Getting Pre-Approval Before You Choose a Structure

Pre-approval shows how much a lender is likely to lend, and it is the point where fixed, variable and split structures can be compared with real numbers. It is not a final approval, and conditions apply.

If your plans include a scheme that has its own approval step, get conditional approval first. Housing Australia states that a buyer should not put down a deposit or bid at auction before this approval is in place. Local buyers can also read about our Gregory Hills mortgage broker service for more on how we work with the community.
