September 2026 Property Market Update
Spring officially arrives in Adelaide this month, and it lands on a property market behaving quite differently to the spring seasons South Australians have grown used to. National home values fell for a fifth straight month in August, and for the first time this year the downturn has reached Adelaide in a meaningful way. For anyone buying, selling or refinancing over the coming months, that shift changes what preparation looks like.
At Eastern Conveyancing, we watch these figures less for the headline and more for what they mean at the negotiating table and in the contract itself. A softer market changes the balance of risk between buyer and seller, and that is exactly where a conveyancer’s review of a contract earns its keep.
MARKET SNAPSHOT: A FIFTH STRAIGHT MONTHLY FALL, NATIONALLY
According to Cotality’s Home Value Index, the national measure of home values fell 0.9% in August 2026, the fifth consecutive monthly decline since the current downturn began. Values nationally now sit 3.6% below the market peak recorded in March 2026. Sydney led the falls at 1.4% for the month, and Cotality reported that 93% of capital city suburbs recorded a decline in value over winter, a sign the slowdown has broadened well beyond the most expensive markets.
ADELAIDE JOINS THE DOWNTURN
Adelaide recorded its third consecutive monthly fall in August, with values down 0.8% for the month according to Cotality, a sharper decline than the 0.2% falls recorded in June and July. Even so, Adelaide dwelling values remained roughly 10% higher than a year earlier as at July 2026, so the market is cooling from a position of considerable strength rather than falling from nowhere. Supply has also normalised: Adelaide’s stock of homes for sale sat around 2.2% above the five-year average in July, a sharp turnaround from the 38% undersupply recorded back in January.
RBA HOLDS AT 4.35%, NEXT DECISION DUE LATE SEPTEMBER
The Reserve Bank left the cash rate on hold at 4.35% at its 10-11 August meeting, the second consecutive hold, while Governor Michele Bullock kept the door open to a further increase if inflation, currently at 3.8%, does not keep easing toward the RBA’s 2-3% target band. The Board’s next decision is due on 28-29 September 2026. For anyone with a finance clause in a contract nearing settlement, that meeting date is worth diarising, since a rate change so close to settlement can affect a buyer’s final borrowing capacity.
AN UNUSUAL SPRING FOR SELLERS AND BUYERS
Spring usually brings a seasonal lift in new listings across Adelaide as sellers time their campaigns for the warmer months. Cotality’s research team has flagged that this year’s lift is likely to be more modest than usual, with many vendors choosing to wait out the softer conditions rather than list into a buyer’s market. Nationally, home sales are tracking around 15.5% lower than a year ago, auction clearance rates have stayed below 50% since late May, and vendor discounting has widened. In practice, that means less competition for the buyers who are active, and more room for both sides to negotiate on price, settlement date and special conditions.
What this means for buyers and sellers in South Australia:
– Buyers now have more room to negotiate on price, deposit terms and settlement timing than they have for several years, but should still have contracts reviewed before signing, since a softer market does not remove legal risk.
– Sellers listing this spring should expect longer selling times and be realistic on price; a well-prepared Form 1 (Vendor’s Statement) and clear title can shorten the path to a signed contract when there are fewer active buyers.
– Investors weighing up a purchase should factor holding costs into their numbers carefully, given the RBA has not ruled out a further rate rise.
WHY CONVEYANCING MATTERS IN A COOLING MARKET
At Eastern Conveyancing, we assist clients across South Australia, including Adelaide and surrounding suburbs, by reviewing contracts before signing, identifying risks early, and helping settlement proceed with as few surprises as possible. In a market where buyers and sellers are negotiating harder on price and terms, the contract itself carries more weight than it did twelve months ago. Getting the finance clause, settlement date and special conditions right the first time avoids costly disputes later.
FINAL THOUGHTS
Spring 2026 is shaping up as a genuine buyer’s market in Adelaide, a change from the seller-favoured conditions of the past two years. Whether you are buying, selling or holding, the fundamentals of good conveyancing do not change: read the contract carefully, understand your dates, and get advice before you sign.
