Proven Tips to Lock Fixed Rate Loans as First Home Buyers

Fixed rate loans give you a set interest rate for a specific period, usually between one and five years.

That predictability matters when you're stretching your budget to get into the market. You know exactly what your repayments will be, and you can plan around that number without worrying about rate rises wiping out your buffer. But the trade-off is real. Most fixed rate products limit your offset account access, cap extra repayments, and charge break fees if you need to sell or refinance early. For first home buyers in Victoria, the question isn't whether to fix or not. It's how much to fix, and for how long.

Why Fixed Rate Terms Matter More for Victorian First Home Buyers

Fixed rate terms directly affect how long you're protected from rate movements and how quickly you can adapt if your circumstances change. A one-year fixed rate gives you short-term certainty but requires you to make another decision when it ends. A five-year fixed rate locks you in for longer, which sounds appealing until you realise you might want to sell, refinance, or make larger repayments before that term ends.

Consider a buyer purchasing in Geelong with a 10% deposit. They're using the Regional First Home Buyer Guarantee to avoid Lenders Mortgage Insurance. They fix the entire loan at a rate that feels comfortable now. Two years later, they receive an inheritance and want to pay down the loan. The lender allows $10,000 in extra repayments per year, but they want to contribute $40,000. The break cost to exit the fixed term early is around $6,000. They either pay the fee or leave the money sitting elsewhere, earning less than the loan is costing them.

The Split Between Fixed and Variable Rates

You don't have to fix the entire loan. Splitting your loan between fixed and variable portions lets you lock in certainty on part of your debt while keeping flexibility on the rest. The variable portion usually comes with full offset account access and unlimited extra repayments, so you can still chip away at the loan without penalty.

A typical split is 50/50, but the right balance depends on how much certainty you need versus how much flexibility you want to keep. If your income is stable and you don't expect windfalls, you might fix 70% and keep 30% variable. If you're expecting bonuses, tax refunds, or help from family, you might reverse that ratio.

When structuring a home loan application, the split needs to be set up before settlement. You can't easily adjust it later without refinancing or paying break costs. That makes it worth spending time on upfront, rather than defaulting to whatever the lender suggests.

How Long Should You Fix Your First Home Loan

The right fixed term depends on how long you plan to stay in the property and how much your financial situation might change. Most first home buyers in Victoria are better off with shorter fixed terms, usually one to three years, because their circumstances tend to shift more than they expect.

In our experience, buyers who fix for five years often regret it. They get a promotion and want to pay off more. They need to move for work. They have a child and want to upsize. Or rates drop and they're stuck paying more than the variable rate for another two years. The longer the fixed term, the higher the risk that something changes and the fixed rate becomes a liability instead of a benefit.

If you're buying in a regional area under the Regional First Home Buyer Guarantee, you might be more likely to move within a few years as your career or family situation shifts. A two-year fixed term gives you enough protection to settle into the property without locking you in for too long.

What Happens When Your Fixed Rate Term Ends

When your fixed term expires, your loan automatically reverts to the lender's standard variable rate unless you take action. That revert rate is usually higher than the advertised variable rate for new customers, sometimes by 0.5% to 1%. On a loan of $450,000, that difference adds up to hundreds of dollars per month.

You have a few options at that point. You can negotiate a new fixed rate with your current lender, switch to their variable rate and ask for a discount, or refinance to another lender offering lower rates. The choice depends on what rates are doing at the time and whether your current lender is willing to match what's available elsewhere.

This is where working with a mortgage broker makes a tangible difference. We monitor your fixed rate expiry dates and reach out before they hit, so you're not caught off guard by a sudden rate jump. We can also negotiate with your lender or arrange a refinance to a lower rate without you having to do the legwork.

Fixed Rate Loans and First Home Buyer Schemes

The First Home Loan Deposit Scheme and Regional First Home Buyer Guarantee both work with fixed rate loans, but the lender you choose affects your options. Not every lender on the government panel offers competitive fixed rates, and some have stricter conditions around splits or extra repayments.

If you're relying on one of these schemes to buy with a 5% deposit, it's worth comparing which lenders offer both access to the scheme and flexible fixed rate terms. Some will let you fix part of the loan and keep the rest variable with a full offset account. Others force you to choose one or the other.

Victorian first home buyers also need to factor in stamp duty concessions when planning their budget. If you're buying below the threshold for the concession, you'll have more cash left over for furniture, repairs, or keeping in offset. That extra buffer can make a variable portion more useful, because you can use the offset to reduce interest without locking funds into the loan.

Break Costs and Why They're Not Always as Bad as They Sound

Break costs are the fee lenders charge if you pay off a fixed rate loan early. The calculation is based on the difference between the rate you're paying and the rate the lender can earn by lending that money out again. If rates have risen since you fixed, the break cost is usually small or even zero. If rates have fallen, the break cost can be significant.

As an example, someone fixes $400,000 at 6% for three years. A year later, rates drop to 5%. They want to refinance to take advantage of the lower rate. The lender calculates the break cost based on the lost interest over the remaining two years of the fixed term. The break cost might be $8,000. If the refinance saves them $150 per month, it takes around four years to recover that cost. In that scenario, it doesn't make sense to break the loan.

But if the break cost is $2,000 and the refinance saves $200 per month, you're ahead in 10 months. The math changes depending on the numbers, which is why blanket advice about fixed rate loans doesn't work. You need to run the calculation for your specific loan and circumstances.

How to Structure Your Fixed Rate Loan When You Apply

When you're filling out your home loan application, the lender will ask how much you want to fix and for how long. Don't rush that decision. Ask your broker to model a few scenarios: fixing 50% for two years, fixing 70% for three years, and staying fully variable. Look at the repayments, the flexibility, and what happens if rates rise or fall.

You should also confirm what the fixed rate product allows. Can you make extra repayments? How much? Can you access an offset account on the variable portion? What are the break costs if you need to sell or refinance? These details aren't always obvious from the lender's website, and they vary significantly between products.

If you're planning to use the First Home Super Saver Scheme to boost your deposit, check when those funds will be available and whether they'll arrive before settlement. If they're delayed, you might need a slightly different loan structure to cover the gap, and that can affect whether fixing makes sense.
