A home loan is likely the largest financial commitment you’ll ever make, and the difference between a good choice and a poor one can cost, or save, tens of thousands of dollars over the life of the loan. Yet many first-time buyers choose based on the advertised rate alone, missing the details that actually matter. Here’s the plain-language guide to choosing a home loan and getting it right. [PUBLISHING NOTE: this is general education, not financial advice; interest rate settings shift, so it deliberately avoids quoting specific rates.]
Understand the Two Main Loan Types
The first decision is fixed versus variable, and each suits different circumstances. A variable-rate loan moves up and down with the market, when the RBA and lenders adjust rates, your repayments change. The advantage is flexibility (usually easier to make extra repayments, redraw, or refinance) and you benefit if rates fall. The risk is that repayments rise if rates go up.
A fixed-rate loan locks your interest rate for a set period, typically one to five years. The advantage is certainty, your repayments won’t change during the fixed term, which helps budgeting. The trade-offs are less flexibility (extra repayments are often capped, and breaking a fixed loan can be expensive) and you don’t benefit if rates fall.
Many buyers choose a split loan, part fixed, part variable, to get some certainty and some flexibility. There’s no universally right answer; it depends on your need for stability versus flexibility, and your read on where rates are heading.
Look Beyond the Advertised Rate
The single biggest mistake is comparing loans on the headline interest rate alone. The advertised rate is only part of the cost. Always check the comparison rate, which factors in most fees and gives a truer picture of the total cost.
Then look at the fees themselves: application or establishment fees, ongoing monthly or annual account fees, and exit or discharge fees. A loan with a slightly lower rate but high fees can cost more than one with a marginally higher rate and no fees. The real question is the total cost over time, not the number in the ad.
Check the Features That Save You Money
The right features can save you far more than a small rate difference. An offset account, a transaction account linked to your loan where your balance reduces the interest charged, can save substantial interest and is genuinely valuable if you keep a reasonable balance. A redraw facility lets you access extra repayments you’ve made if you need them. And the ability to make extra repayments without penalty helps you pay the loan off faster.
Weigh these against any cost. Sometimes a loan with an offset account carries a slightly higher rate or fee, but if you’ll use the offset well, it can more than pay for itself.
Understand How Much You Can Actually Borrow
Before falling in love with a loan or a property, understand your genuine borrowing capacity. Lenders assess your income, expenses, existing debts and the deposit you have. They also “stress test” your ability to repay at a higher rate than the current one, so approval isn’t based on today’s rate alone.
Getting pre-approval gives you a clear budget and strengthens your position when you buy, but remember pre-approval isn’t a guarantee, final approval depends on the specific property and your circumstances at settlement.
Consider Using a Mortgage Broker
You can go directly to lenders, or use a mortgage broker who compares loans across many lenders on your behalf. A good broker can save you time and help you find a suitable loan, and brokers are typically paid by the lender rather than you, though you should ask about how they’re paid and whether they cover the whole market or a limited panel. Brokers must act in your best interests under Australian law, but it’s still worth understanding their range and incentives.
The Traps to Avoid
A few that cost buyers. Don’t choose on the advertised rate alone, check the comparison rate and fees. Don’t over-borrow to your absolute maximum, leave a buffer for rate rises and life changes. Don’t ignore useful features like offset accounts that could save you more than a small rate difference. And don’t rush, this is a decades-long commitment worth getting right. Independent guidance is available through the government’s Moneysmart site.
Your Home Loan Checklist
When comparing loans, check: fixed, variable or split, and which suits your need for certainty versus flexibility; the comparison rate, not just the advertised rate; all the fees; valuable features like offset and extra repayments; your genuine borrowing capacity with a buffer; and whether a broker could help you compare more widely. Weigh the total cost and fit, not the headline number.
The Bottom Line
Choosing a home loan well is about looking past the advertised rate to the total cost, the fees, the comparison rate, and the features that genuinely save you money. Understand fixed versus variable, borrow with a buffer rather than to your limit, and consider a broker to compare widely. Get it right and you could save tens of thousands over the life of the loan, which makes the homework some of the most valuable you’ll ever do.
