Top 10 Fixed Rate Features First Home Buyers Need

What Does a Fixed Rate Loan Actually Lock In?

A fixed rate loan locks in your interest rate for a set period, typically between one and five years. During that time, your repayments stay the same regardless of what happens to variable rates in the market.

Consider a buyer who settled on a unit in Thornlie in early 2024 with a three-year fixed rate at 5.8%. When variable rates climbed above 6.5% later that year, their repayments stayed unchanged. They knew exactly what would leave their account each fortnight, which made budgeting around other settlement and moving costs predictable. At the end of the fixed period, the loan reverts to the lender's variable rate unless you refinance or negotiate a new fixed term.

Most lenders offering home loans for first home buyers provide fixed rate options, but the features attached to those products vary widely. Choosing a fixed rate is not just about the headline rate. The features determine whether the loan works with how you actually live.

Can You Make Extra Repayments on a Fixed Rate Loan?

Most fixed rate loans allow extra repayments up to a capped amount each year, commonly between $10,000 and $30,000. Anything beyond that cap attracts break costs.

A buyer in Thornlie purchasing a townhouse under the Australian Government 5% Deposit Scheme might receive a tax refund or work bonus during the fixed period. If their loan permits $20,000 in additional repayments per year, they can put that money toward the mortgage without penalty. If the loan has no extra repayment allowance at all, that refund either sits in a savings account earning minimal interest or triggers a break fee if paid into the loan.

Always confirm the extra repayment limit in writing before committing to a fixed rate product. Some lenders advertise flexibility but bury restrictions in the fine print.

Do Fixed Rate Loans Include Offset Accounts?

Most fixed rate loans do not include a full offset account. Some lenders offer a partial offset, where only a percentage of your account balance reduces the interest charged, or no offset at all.

Without an offset, any savings you accumulate during the fixed period sit in a separate account earning taxable interest rather than reducing your mortgage interest. For someone buying in Thornlie who plans to save aggressively after settlement, this can add up. A buyer with $15,000 sitting in a standard savings account at 3% earns around $450 in interest per year but pays tax on that amount. The same $15,000 in a full offset account on a loan charging 6% would save $900 in interest with no tax implication.

If you expect to hold surplus cash during the fixed period, either choose a variable loan with offset or accept that a fixed rate will cost you that flexibility. Some buyers split their loan between fixed and variable to access offset benefits on the variable portion while locking in certainty on the rest.

What Happens If You Need to Sell Before the Fixed Period Ends?

If you sell your property or pay out your loan before the fixed period ends, you may face break costs. These costs compensate the lender for the difference between the rate you locked in and the rate they can now lend that money at.

Break costs are calculated using a formula that considers the remaining term, the amount being repaid, and the movement in wholesale interest rates since you fixed. If rates have fallen since you locked in, break costs can be substantial. If rates have risen, the break cost may be zero or minimal.

In Thornlie, where the housing market has seen steady activity, buyers who fixed at lower rates in previous years and then sold to upgrade faced break costs in some cases exceeding $10,000. Lenders are required to provide a break cost estimate before settlement, but these estimates can change depending on rate movements. If there is any chance you will sell, refinance, or pay out the loan early, factor potential break costs into your decision or choose a shorter fixed term.

Redraw Facilities on Fixed Rate Loans

A redraw facility lets you withdraw extra repayments you have already made, but access and conditions vary between lenders. Some allow unlimited free redraws. Others charge a fee per withdrawal or limit how often you can access funds.

A buyer in Thornlie who makes an extra $15,000 in repayments during the first year might need to access $5,000 of that for urgent car repairs. If the loan includes free redraw with online access, they can withdraw the funds immediately. If redraw requires a phone call, a $50 fee, and three days processing, the feature is less useful in an emergency.

Redraw is different from an offset. Money in redraw has already been paid into the loan and reduces your principal. Money in offset stays separate and can be withdrawn at any time without approval. For first home buyers who value liquidity, offset is superior. For those prioritising lower rates, a fixed loan with reasonable redraw terms may be enough.

Portability: Can You Take Your Fixed Rate to a New Property?

Some lenders allow you to port your fixed rate loan to a new property if you sell and buy during the fixed period. This avoids break costs and lets you keep the rate you locked in.

Portability is not automatic. The new property must meet the lender's security requirements, and you must meet their serviceability criteria at the time of the new purchase. If you are buying a property in Thornlie and expect to upgrade within a few years, check whether your lender offers portability and under what conditions. Not all lenders provide this feature, and those that do often apply strict terms.

If portability is important to you, discuss it during the application stage and have the terms documented. Assuming you can port your loan without confirming the lender's policy can leave you exposed to unexpected break costs.

Fixed Rate Discounts and Honeymoon Rates

Some lenders offer an introductory discount on fixed rates for the first year, after which the rate increases for the remainder of the fixed term. These are sometimes called honeymoon rates.

A loan advertised at 5.5% fixed for three years might actually be 5.5% in year one, then 6.2% for years two and three. The average rate over the term is higher than the headline figure suggests. Compare the blended rate over the full term rather than focusing only on the first year. Lenders are required to disclose the comparison rate, which helps, but you need to calculate what your actual repayments will be in each year of the fixed period.

If a lender offers a discount that seems unusually low, ask whether the rate changes during the fixed term and request a repayment schedule showing each year separately.

Can You Split Your Loan Between Fixed and Variable?

Many lenders allow you to split your loan so that part is fixed and part remains variable. A common split is 50/50, but you can choose any ratio that suits your circumstances.

Splitting gives you some rate certainty while retaining access to features like offset and unlimited extra repayments on the variable portion. For first home buyers in Thornlie using the 5% Deposit Scheme, a split structure can work well. You lock in part of the loan to protect against rate rises, then use the variable portion to park savings in offset or make larger extra repayments when your income allows.

Some lenders charge separate fees for each split portion, so confirm the total cost structure before proceeding. The flexibility of a split can justify the additional complexity, but only if the features align with how you plan to manage the loan.

What Happens at the End of the Fixed Period?

When your fixed rate term ends, the loan automatically reverts to the lender's standard variable rate unless you take action. That reversion rate is almost always higher than the advertised variable rate offered to new customers.

If you do nothing, you may end up paying 0.5% to 1% more than you need to. Around three months before your fixed term expires, contact your lender or a broker to review your options. You can negotiate a new fixed rate, switch to a competitive variable rate, or refinance to another lender.

Buyers in Thornlie who locked in rates during lower rate environments and did not review their loan at the end of the fixed term have, in some cases, seen repayments increase sharply due to both rate rises and reversion to a higher product. Planning ahead prevents that surprise. Set a reminder six months before your fixed term ends and start comparing products then. For guidance on managing a fixed rate expiry, speak to a broker who can access multiple lender rates and identify the most competitive option for your circumstances at that time.

Call one of our team or book an appointment at a time that works for you to discuss which fixed rate features align with your plans and how to structure your loan to support both short-term certainty and long-term flexibility.
