The average South Australian homeowner is paying more than $20,000 in annual home loan repayments than they were a decade ago, new data shows.
Compare The Market analysis of PropTrack data reveals the typical SA homeowner is forking out $1751 more per month than they were a decade ago, with monthly repayments now sitting at $3901.
This compares with the $1747 they were paying a decade ago, and results in an extra $21,012 over the course of a year.
Repayments were based on RBA data on average variable rates at 5.5 per cent in September 2025 and 5.46 per cent in September 2015, and reflects a 99 per cent increase in average loan size in that time from $309,000 in 2015 to the current $616,000.
The suburbs with the greatest increase, based on a loan to value ratio of 80 per cent – or those bought with a 20 per cent deposit – are the leafy eastern suburb of Burnside, where annual repayments are up almost $51,000 a year, Beaumont where they are up by almost $49,000 a year and Brighton where annual mortgage repayments are up by almost $42,000.

“The path to homeownership in Australia isn’t easy, and these figures tell us why,” Mr Winter said.
“So often the emphasis is put on raising a deposit but for many the real challenge begins when they start servicing their loan.
“And if the cash rate goes up again this year, I think a lot of people are really going to feel it.”

Blackfish Finance founder and mortgage broker Leah Busby said home prices had increased significantly over the past decade, so it was natural average loan values would follow.

“It’s a combination of clients wanting and needing to spend more money now, but also clients are growing with that cost, so while a decade ago they might have been a first-home buyer, now they’re in their family home and have kids, and they might have been graduates previously but now they’re high up in their careers.

Magain Real Estate agent Travis Denham, who lives at North Brighton, said his mortgage repayments were more than a decade ago.
“In this time though we have upgraded our home and along with that comes higher repayments,” he said.
“It is still the number one expense in our household however and one we keep a close eye on.
“With the ever rising cost of living, making sure we are careful to budget for all expenses, including the mortgage is important.
“In our household we generally make sure the mortgage, bills, shopping budget is covered off first before we spend on discretionary items.”
