What should I look for when comparing home loans?

When comparing home loans, the key things to look out for are:

Interest rates
The most popular way to compare home loans. A low interest rate will help you save money, however it’s important to compare loans using the comparison rate. The comparison rate includes any additional fees and charges and reflects the true cost of the loan. You’ll find the comparison rate listed next to the interest rate.
You’ll also get the choice between a fixed-rate loan or a variable rate loan. Learn more about the difference between fixed and variable interest rates.

A low interest rate is just the beginning. The right features can make a big difference over the life of your loan.

Some clever features to look out for are fee-free extra repayments, so you can pay down your home loan sooner and a free redraw facility (in case you need your extra repayments).

If you have some extra savings, an offset account is another useful feature that can help you save money on interest.

Compare our home loans and features today.

Most home loans have an establishment fee, however it’s important to check for ongoing fees such as a monthly or annual fee. Or a fee for making extra repayments. Ongoing fees add to the cost of your home loan and can sometimes cancel out a low interest rate.
You can use the loan comparison calculator to easily check the full cost of your loan and find the loan that will give you the best chance of saving money.

It’s normal to take your time when looking for a home loan and comparing before you commit is the best way to find the loan that’s right for you.

1 Discounts off the Offset Variable Reference Rate are available to (a) new home loans with a minimum application amount of $100,000; or (b) switching or restructuring of the home loan you already have with us when it includes new borrowing of at least $10,000; and the application is unconditionally approved on or after 8 May 2024.

Interest rates and discounts vary based on the loan purpose (owner occupier or investor), repayment type (principal and interest, interest only, construction) and Loan to Value Ratio (LVR).

3 LVR means ‘Loan to Value Ratio’. It is the amount of your loan divided by the valuation of your property, calculated as a percentage. For example, if you apply for a loan of $400,000, which will be secured by a property valued at $500,000, your LVR is 80%. We calculate your LVR at the time we approve your loan and your discount won’t change because of changes to the LVR during the life of your loan.

Applying for pre-approval allows you to know the maximum amount you can borrow while you look for a property.

Pre-approval means that a lender has agreed to lend you an amount of money in-principle, but the loan hasn't been proceeded to full or final approval.

While pre-approval is not a fully approved loan it can help you narrow your search, negotiate, and make an offer with certainty and confidence.
