Average Australian Mortgage Statistics: Key Insights for Homeowners and Buyers in 2025

As we head into 2025, the Australian housing market continues to be a focal point for homeowners and potential buyers. If you’re looking to buy your first home or find your next property, it’s essential to understand the current mortgage landscape. Here’s a breakdown of the key mortgage stats in Brisbane and across Australia. 

Average Australian Mortgage Size 2025

According to the latest data from the Australian Bureau of Statistics (ABS), the average new owner-occupier home loan in Australia is $642,121. This figure represents the amount people are borrowing to purchase homes they will live in, but loan amounts vary depending on location and property type. With average interest rate estimates ranging from 6.04% to 6.55% per annum, the monthly repayments could range from around $3,910 to $4,000.

In Queensland, the average loan size is somewhat lower than the national average, reflecting the more affordable property market in comparison to New South Wales or Victoria. The average mortgage for an owner-occupier in Brisbane is $619,599. However, if you’re looking to buy in suburbs with higher demand and higher property prices, such as those closer to the city or in sought-after areas, you may find that the loan amount you’ll need could be higher.

What Does This Mean for SELLERS?

The latest mortgage statistics for 2025 provide valuable insights for home sellers as well. Here’s how the current landscape impacts you:

Increased Borrowing Challenges for Buyers: With rising loan amounts and interest rates pushing average repayments higher, buyers are facing greater financial strain. This could mean a smaller pool of potential buyers, as affordability becomes a critical factor.

Affordability in Brisbane is a Selling Point: Brisbane’s relatively lower average mortgage size and repayments compared to Sydney and Melbourne position it as a more attractive market for buyers. Highlighting the affordability of your property in Brisbane could draw interest from interstate buyers seeking value.

Income Pressures May Influence Offers: With over 50% of income now required to service mortgages in Brisbane, buyers may approach negotiations more cautiously. Sellers should be prepared for buyers prioritising affordability, which could affect pricing and negotiation strategies.

Strategic Marketing is Key: Emphasising features that offer value for money—such as energy efficiency, location advantages, or investment potential—can make your property stand out in a competitive market.

By understanding the financial pressures buyers face, you can tailor your approach to selling, set realistic expectations, and position your property effectively in the current market.

What Does This Mean for BUYERS?

The Australian mortgage market in 2025 highlights a shift in the cost of homeownership. While loan amounts and repayments vary depending on your location, the increasing portion of income required to cover mortgage costs is a national trend. In Brisbane, buyers face a greater financial burden compared to previous years, with the portion of income required to service a mortgage now surpassing 50%.

However, despite these challenges, Brisbane remains a relatively affordable city compared to the likes of Sydney or Melbourne. The key for prospective buyers is to stay informed, assess their financial situation carefully, and plan accordingly.
