Adelaide Property Market – Prices, Trends, Forecast [October 2026]

The tightest rental market among Australia’s capitals has not insulated Adelaide from falling property values. Vacancy stood at 1.4% in September 2026, highlighting scarce rental accommodation while prices retreated from their recent record peak. This contrast has a practical consequence: easing purchase values do not mean housing pressures are easing equally, with both house and unit rents higher than a year earlier.

Key Takeaways

• Rental scarcity distinguishes Adelaide, with September vacancy of 1.4% the lowest among the capitals.
• Dwelling values fell 1.3% in September and 2.7% over the quarter but remained 6.5% higher than a year earlier.
• Estimated median values were $990,531 for houses and $674,188 for units.
• Annual rent growth reached 6.3% for houses and 6.1% for units.
• Further easing is more likely than a quick recovery as national mortgage costs and weak confidence constrain purchasing capacity.

Adelaide Property Price Growth

The retreat from May’s record peak reached 2.9% by September 2026, although Adelaide dwelling values remained 6.5% higher annually. Values fell 1.3% in September and 2.7% over the quarter, leaving year-to-date growth at 1.8%. Longer-term gains remained substantial, at 59.3% over five years and 104.3% over a decade.

Houses and units recorded broadly similar annual growth of 6.5% and 6.2%, respectively. Both weakened over the quarter, with units recording a larger decline. Estimated median values were $990,531 for houses and $674,188 for units, with dwellings overall at $928,560. Local annual results were stronger in Onkaparinga, up 10.1%, and Gawler–Two Wells, up 9.6%, showing that parts of Greater Adelaide retained larger gains than the citywide average.

Adelaide Property Market Trends

Rental scarcity continues to distinguish Adelaide within a softer national purchasing environment. Collectively, capital-city homes took a median 39 days to sell, compared with 23 a year earlier, as advertised stock expanded buyer choice. Nationally, auction clearance rates remained below average, while buyers had less urgency and greater negotiating scope.

The September vacancy rate of 1.4% was the lowest among capitals. House rents rose 6.3% over the year and unit rents increased 6.1%, keeping accommodation costs higher across both property types.

Units offered a gross rental yield of 4.5%, against 3.5% for houses and 3.6% across dwellings. This yield advantage does not establish net profitability: nationally, high interest, insurance, maintenance and strata expenses continue to weigh on investment cash flow.

Here’s how values have shifted across the main regions and timeframes.

Adelaide Property Market Forecast

A 1.4% vacancy rate offers no guaranteed protection against further price declines in Adelaide. Nationally, higher mortgage costs and weak confidence are restricting purchasing capacity, pointing to continued near-term price pressure rather than a quick recovery. Against that, Australia’s construction costs, capacity constraints and long delivery timelines are limiting new housing supply. Relatively low national unemployment also supports household incomes and may contain forced selling. With demand constrained but these stabilising influences still operating, a gradual easing in values is more likely than a severe downturn over the coming months.

The Reserve Bank of Australia’s ongoing adjustments to interest rates will likely play a crucial role in shaping market dynamics, as higher borrowing costs limit purchasing power for many buyers.

Here are some of the most recent forecasts by the big-4 banks in Australia (Reviewed September 2026):

• ANZ expects capital-city prices to decline in both 2026 and 2027. ANZ forecast coverage
• CBA expects further national price declines before a modest recovery during 2027. CBA housing outlook
• NAB forecasts lower prices across the eight capital cities in 2026. NAB Housing Monitor
• Westpac’s June forecast anticipates flat prices in 2026 and growth in 2027, although its September update warns of further downside. June Housing Pulse, September housing update

For the remainder of 2026 and into 2027, this means:

• A softer near-term outlook: The bank updates point to continued pressure on property prices, replacing the earlier expectation of broadly rising values. NAB.
• Different conditions between cities: Sydney and Melbourne face the largest forecast declines in CBA’s outlook, although weakness has also spread to Brisbane, Perth and Adelaide. CBA.
• Borrowing costs remain important: The timing and strength of any recovery depend partly on interest rates. CBA’s forecast for modest growth in 2027 assumes rate cuts during that year. CBA.
• More negotiating room for buyers: Westpac reports rising listings and expects buyers to have greater bargaining power in many markets heading into spring. This is an interpretation of market conditions, not a guarantee for individual properties. Westpac.
