Fixed Rate Loans & What First Home Buyers Should Know

A fixed rate loan locks in your interest rate for a set period, typically between one and five years.

That certainty appeals to many first home buyers, particularly those on a tight budget who need predictable repayments. But the trade-off is reduced flexibility during the fixed term. You will often lose access to features like offset accounts and unlimited extra repayments, and you will face break costs if you exit the loan early. The right choice depends on whether rate certainty or loan flexibility matters more to your circumstances.

How Fixed Rate Loans Work for First Home Buyers

You apply for a fixed rate loan the same way you would for a variable rate loan. Your home loan application is assessed on income, expenses, deposit, and credit history. Once approved and settled, your interest rate stays the same for the fixed term you choose, regardless of whether the Reserve Bank raises or lowers the official cash rate.

Your repayments stay the same each month. If rates rise, you are protected. If rates fall, you continue paying the higher fixed rate until the term ends. At the end of the fixed period, most loans revert to the lender's standard variable rate unless you negotiate a new fixed term or refinance to a different product.

Consider a buyer purchasing with a 10% deposit under the Australian Government 5% Deposit Scheme. They fix the rate for three years to match the period they expect their income to remain stable. The fixed rate gives them repayment certainty while they adjust to homeownership costs. When the fixed term ends, they can reassess their situation and decide whether to fix again, switch to variable, or refinance based on their equity position and financial goals at that time.

What You Give Up During the Fixed Period

Most fixed rate loans do not offer a full offset account. Some lenders provide a partial offset or redraw facility, but these are less common on fixed products and often come with conditions. If you rely on an offset account to reduce interest or park savings, a fixed rate loan may not suit your needs.

You are usually limited in how much extra you can repay each year without incurring a fee. Many lenders cap additional repayments at $10,000 to $30,000 per year during the fixed term. If you receive a bonus, inheritance, or other lump sum and want to pay down the loan quickly, you may be charged break costs on any amount above the cap.

If you sell the property or refinance before the fixed term ends, you will likely pay break costs. These costs can run into thousands of dollars depending on how much rates have moved since you fixed. Break costs are calculated based on the economic loss to the lender. If current rates are lower than your fixed rate, the lender has lost the opportunity to lend that money at the higher rate, and you pay the difference.

Split Loans as a Middle Option

A split loan divides your borrowing between a fixed rate portion and a variable rate portion. You might fix 50% of the loan and leave 50% variable, or choose any split that suits your situation.

The variable portion gives you access to an offset account and unlimited extra repayments. The fixed portion provides repayment certainty on part of the loan. If you need to exit early, you only pay break costs on the fixed portion, and the variable portion remains flexible.

In our experience, buyers who expect irregular income or lump sum payments often benefit from a split structure. A buyer working in a commission-based role might fix 60% of the loan for stability and keep 40% variable to absorb extra repayments when commissions come through. The split structure costs nothing extra to set up and can be tailored to match your cash flow.

Fixed Rate Loan Features That Do Exist

Some lenders offer portability, which allows you to transfer your fixed rate loan to a new property without paying break costs. Portability is not standard and must be checked with the lender before you rely on it. If you think you might move during the fixed term, confirm whether portability is available and what conditions apply.

A few lenders allow rate lock extensions, which let you extend a locked rate if settlement is delayed. This feature is uncommon on fixed rate products and usually comes with a fee or time limit.

Most fixed rate loans allow you to make scheduled repayment frequency changes, such as switching from monthly to fortnightly repayments, without penalty. You cannot increase the repayment amount beyond the lender's extra repayment cap, but changing the frequency is generally permitted.

When a Fixed Rate Loan Makes Sense

If your income is stable and you have minimal savings beyond your deposit and settlement costs, locking in repayments for two to three years can give you breathing room to build a buffer. You know exactly what your repayments will be, and you can budget around that figure without worrying about rate rises.

If you are borrowing close to your maximum borrowing capacity, a fixed rate protects you from payment shock if rates increase. A modest rate rise on a large loan can add hundreds of dollars to your monthly repayment. Fixing eliminates that risk during the fixed term.

If you are planning to hold the property for at least the length of the fixed term and do not expect to make large extra repayments, a fixed rate loan may suit your situation. The reduced flexibility will not cost you anything if you were not planning to use those features in the first place.

When to Avoid Fixing or Use a Split Instead

If you expect to sell or refinance within the next two to three years, a fixed rate loan will likely cost you more in break fees than you save in interest. A variable rate loan or split loan with a smaller fixed portion gives you more flexibility to exit without penalty.

If you have irregular income or expect lump sum payments during the fixed term, a variable rate loan or split structure will let you make extra repayments without hitting the lender's cap. Paying down your loan faster reduces the total interest you pay over the life of the loan, and a fixed rate product limits your ability to do that.

If you want to use an offset account to reduce interest, most fixed rate loans will not give you that option. A variable rate loan or the variable portion of a split loan will.

What Happens at the End of the Fixed Term

When your fixed term ends, your loan will revert to the lender's standard variable rate unless you take action. The standard variable rate is usually higher than the advertised rate the lender offers to new customers. You should contact your lender or broker at least 90 days before the fixed term expires to negotiate a new rate or refinance to a different lender.

Many buyers assume the reversion rate will be close to the rate they see advertised. It is often 0.50% to 1.00% higher. On a $500,000 loan, a 1.00% rate increase adds roughly $400 to $500 to your monthly repayment. If you are not paying attention when the fixed term ends, you could be paying more than you need to.

Your fixed rate expiry is a natural point to reassess your loan structure. You may have built equity since you purchased, which could give you access to lower rates or remove the need for lenders mortgage insurance if you refinance. You may also have different financial priorities than when you first bought, and your loan structure should reflect that.
