What are Fixed Rate Loans for First Home Buyers?

Fixed Rate Loans Lock In Your Repayment Amount

A fixed rate loan sets your interest rate for a defined period, usually between one and five years. Your repayment stays the same for the entire fixed term, no matter what happens to the cash rate or what other lenders are charging. After the fixed term ends, your loan reverts to a variable rate unless you fix again.

For tradies buying their first place, the appeal is obvious: you know exactly what's leaving your account every fortnight, which makes budgeting straightforward when you're managing irregular income, seasonal work, or lumpy cash flow between jobs. But fixed rates come with trade-offs, and whether they suit depends on where you're at in your working life and what you need the loan to do over the next few years.

How Fixed Rates Fit Different Life Stages

Fixed rates work when your financial situation is stable enough that you won't need to make changes to the loan before the fixed term ends. If you're a couple of years into your trade, earning consistent wages, and planning to stay in the same job and the same house for the next three to five years, a fixed rate can give you certainty while you get your deposit and spending under control.

Consider an electrician who's been working for a mid-sized contractor for three years, just bought a unit within 20 minutes of the depot, and plans to stay put while building up savings. Fixing for three years means the repayment won't move, even if rates climb. That consistency makes it easier to set money aside without second-guessing the budget every quarter.

But if you're newly qualified, still working out whether you'll stay with your current employer or go out on your own, or you've bought a place that might not suit you in two years, a fixed rate can box you in. You can't make extra repayments beyond a small annual cap without copping break fees, you generally lose access to an offset account, and if you need to sell or refinance before the term ends, the cost to exit can run into the thousands.

For first home buyers who are still figuring out their next move, that lack of flexibility is a bigger problem than rate movement.

What You Give Up When You Fix

Most fixed rate loans don't come with an offset account. If you're the kind of tradie who keeps a buffer in the bank for tools, materials, or quiet months, that buffer won't reduce the interest you're paying on the loan. On a variable loan with offset, parking $15,000 in the offset account saves you interest on that $15,000 every day it sits there. On a fixed loan, it just sits in a savings account earning next to nothing while you keep paying interest on the full loan balance.

You also can't make unlimited extra repayments. Most lenders cap additional payments at around $10,000 to $30,000 per year on a fixed loan. If you land a big job, sell a car, or get a decent tax return and want to throw $40,000 at the mortgage, you'll either pay break fees on anything over the cap or have to park the excess somewhere else.

And if you need to refinance or sell before the fixed term ends, break costs apply. These are calculated based on the difference between your fixed rate and the wholesale rate the lender can now get for the remaining term. If rates have dropped since you fixed, the break cost can be substantial. If rates have risen, the break cost might be zero, but you're stuck with a higher rate than what's available elsewhere until the term expires.

Split Loans Let You Hedge Without Committing Fully

A split loan divides your borrowing between fixed and variable portions. You might fix 50% for three years and leave 50% variable, or fix 70% and keep 30% variable. The variable portion keeps your offset account active, lets you make unlimited extra repayments on that chunk, and gives you flexibility to refinance or adjust without breaking the entire loan.

In our experience, this setup works well for tradies who want some repayment certainty but aren't prepared to give up all their flexibility. The fixed portion anchors your minimum repayment, while the variable portion absorbs extra cash flow and keeps your options open.

Consider a plumber who's just gone out on his own after five years working for someone else. Income is solid but less predictable than wages. He's bought a house he plans to keep for at least five years, but he's not sure whether he'll take on a business partner, buy a ute, or need to refinance for equipment in the next couple of years. Splitting the loan 60% fixed and 40% variable gives him a stable base repayment on the majority of the debt, while the variable portion keeps an offset account running and lets him throw extra repayments at the loan when work is busy without hitting caps or fees.

The split doesn't eliminate risk, but it spreads it. If rates rise, the fixed portion protects part of your repayment. If rates fall, the variable portion benefits immediately, and you're not locked into an above-market rate on the entire balance.

Fixed Rates and Government Schemes

If you're using the Australian Government 5% Deposit Scheme, you can generally choose a fixed rate, variable rate, or split structure, depending on which lender you go through. Not every participating lender offers all three options, so you need to confirm what's available before you commit.

The same applies if you're accessing state-based stamp duty concessions or grants. Most first home buyer schemes don't restrict your choice of loan structure, but the lender's own policy might. Some lenders won't offer a split loan under the 5% Deposit Scheme, while others will. Some cap the maximum fixed term at three years, while others go to five. You need to ask upfront what's on the table, not assume every option is available just because the scheme itself doesn't rule it out.

For tradies using a 5% or 10% deposit, the ability to fix part of the loan can be valuable if your income is still ramping up and you want predictable repayments while you're getting established. But if you're likely to increase your income significantly over the next couple of years and want to smash the loan down quickly, a variable loan or a split with a smaller fixed portion will give you more room to move.

When a Variable Loan Makes More Sense

Variable rates suit tradies who want full control over their loan and expect their financial situation to change in the short to medium term. If you're planning to go from wages to ABN income, buy an investment property, upgrade your home, or refinance to access equity for a work vehicle or tools, you need a loan structure that lets you move without penalty.

A variable loan with an offset account and no restrictions on extra repayments gives you that flexibility. You can pay ahead when cash flow is strong, pull back to minimum repayments when work is quiet, and refinance or restructure whenever it makes sense without worrying about break costs.

For finance for tradies who are still in the early stages of their trade career or who are building a business, that flexibility is usually worth more than rate certainty. You're better off with a loan that adapts to your situation than one that forces you to pay thousands in fees just to make a necessary change.

What to Ask Before You Fix

Before you lock in a fixed rate, you need to know the maximum extra repayment allowed per year, whether you can still access an offset account on any portion of the loan, what the break cost calculation looks like, and whether you can split the loan or switch part of it to variable later without refinancing the whole thing.

You also need to know what rate you're reverting to after the fixed term ends. Some lenders revert to their standard variable rate, which can be significantly higher than their advertised discount variable rate. If you fix for three years and then revert to a rate that's 0.50% higher than what new customers are getting, you've saved nothing unless you're prepared to refinance at the end of the term.

And you need to think about what your life will look like in three to five years. If you're likely to have kids, change jobs, start a business, move suburbs, or want to renovate, a loan that penalises you for making changes isn't the right fit, no matter how attractive the fixed rate looks today.

For home loans for tradies, the right structure depends on your actual circumstances, not just the advertised rate. A fixed rate might give you certainty now, but if it costs you flexibility later, it's not doing its job.
