In short: A fixed-rate home loan locks your interest rate (and repayments) for a set period — certainty, but less flexibility and possible break costs. A variable rate moves with the market — more flexible, with features like offset and extra repayments, but your repayments can rise. Many first home buyers split the loan to get some of both. There’s no universally right answer; it depends on your priorities.
Once you’re approved, the next decision is the loan type. Here’s the honest trade-off for a first home buyer.
Fixed rate — certainty
Your rate and repayments are locked for the fixed term (often 1–5 years). Good if you value predictable budgeting or think rates will rise. The downside: limited or no extra repayments, often no offset account, and break costs if you exit or refinance early.
Variable rate — flexibility
Your rate moves with the market, so repayments can go up or down. The upside is flexibility — typically an offset account, unlimited extra repayments, and easier refinancing. The downside is rate risk: your repayments can rise if rates do.
Split loans — a bit of both
You can split the loan — part fixed, part variable — to get some repayment certainty while keeping some flexibility and offset benefit. Many first home buyers find this a sensible middle ground.
Which suits a first home buyer?
If a rate rise would genuinely stretch you, the certainty of fixing (or a split) can help you sleep. If you want to make extra repayments and keep an offset, variable suits better. A broker models both against your borrowing power and budget. The independent Moneysmart home loans guide is a neutral starting point.
One thing we often notice with first home buyers is that many start by asking, “Should I fix my rate?” but the real question is usually, “How much certainty do I need?” In our recent first home buyer conversations, many buyers preferred the flexibility of a variable loan, while others felt more comfortable fixing part or all of the loan so their repayments felt more predictable. A rough pattern we see is about half choosing variable, a smaller group choosing fixed, and some choosing split loans when they want a bit of both.

Frequently asked questions
Is a fixed or variable home loan better for a first home buyer?
Neither is universally better. Fixed gives certainty; variable gives flexibility and features like offset. If a rate rise would stretch you, fixing or splitting helps; if you want to make extra repayments, variable suits.
What is a split home loan?
A loan divided into a fixed portion and a variable portion, so you get some repayment certainty while keeping some flexibility and offset benefit.
Can I make extra repayments on a fixed loan?
Usually only up to a limit, if at all, and breaking a fixed term early can trigger break costs. Variable loans typically allow unlimited extra repayments.
