Donut Day: national property growth arrives at landmark turning point

The Australian residential property market has officially arrived at a major cyclical turning point.

For the first time since the early phases of the 2025 rate-cutting cycle, national home value growth has flattened to a dead stop. Over the recent 28-day rolling period, the five-city aggregate index recorded exactly 0 per cent growth—a milestone property analysts have dubbed Donut Day.

According to the latest May 2026 data from Cotality, the National Home Value Index rose by just 0.3 per cent over the month, marking the slowest monthly growth increment witnessed since January 2025.

While values technically continue to edge higher on a broad national scale, the annual growth trend, which moved through a cyclical high of 10.0 per cent in February, is now in a state of rapid moderation.

For property investors and industry professionals, however, the national average has become a functional myth. Beneath the flatlining surface lies a brutal, multi-speed fragmentation.

Australia is no longer navigating a singular property cycle; instead, a massive structural divide has opened up between the traditional powerhouse capitals and the ultra-resilient mid-sized markets.

The great capital city divergence

The headline deceleration is being led almost entirely by Sydney and Melbourne, both of which are now firmly entrenched in the early phases of a cyclical downswing.

Each major city recorded a 0.6 per cent drop in dwelling values over the month. Sydney home values now sit 1.0 per cent below their November 2025 peak, while Melbourne has fallen 1.9 per cent below its late-2025 high.

This softer landscape is driven by an ongoing cooling of buyer demand against a backdrop of elevated mortgage rates and tightening borrowing capacities.

Crucially, advertised stock levels have surged in these weakening corridors. Total listings are tracking 12 per cent above the five-year average in Sydney and 3.5 per cent above average in Melbourne, shifting the balance of negotiating power back toward buyers.

This supply accumulation is reflected at auctions, where capital city clearance rates have consistently languished below 55 per cent, with New South Wales tracking at a soft 41 per cent and Victoria hovering at 53 per cent.

In stark contrast, affordable mid-sized capitals are aggressively defying gravity. Perth continues to be the nation’s standout performer, surging another 2.1 per cent in a single month to stretch its rolling annual growth to a staggering 26 per cent. That’s its steepest annual trajectory since 2007.

Darwin followed with a 1.3 per cent monthly gain, pushing both houses and units to concurrent nominal highs. Brisbane (+1.2 per cent) and Adelaide (+1.1 per cent) similarly showed immense resilience, with Adelaide securing its seventh consecutive month of greater-than-1 per cent gains.

In these undersupplied markets, tight stock levels and strong interstate migration continue to fuel intense buyer competition.

The affordability ceiling and the ‘price guide lie’

A key driver of this geographic split is the ‘affordability ceiling’.

Because buyers are hitting strict serviceability limits imposed by financial institutions, purchasing demand has been strongly concentrated below the median price point.

In Sydney, for example, lower-tier housing values actually rose 2.9 per cent year-to-date, contrasting sharply with a 3.3 per cent contraction across the premium upper quartile.

This intensified competition in lower brackets has exacerbated an ongoing transparency crisis on the ground.

Fresh data analysis compiled by proptech app Homer, which reviewed published price guides for residential sales over the six months leading into May, exposed a persistent pattern of underquoting across almost all capital cities.

The Homer data revealed that fewer than 4 per cent of real estate agents nationwide are listing properties within a 3 per cent margin of the final sale price. Instead, hopeful buyers are routinely forced to bid six figures over advertised price guides just to stay in the race.

Perth and Adelaide recorded the highest proportions of above-guide sales, with 76 per cent and 73 per cent of properties overshooting expectations, respectively.

In terms of sheer dollar value, Sydney recorded the largest gap in the country; when a Sydney property sells above its guide, the median overshoot is a punishing $117,500 above the top of the advertised range. Brisbane followed closely with a median overshoot of $100,000.

Once again, Melbourne stands alone as the stark structural outlier. It is currently the only capital city in Australia where more properties are selling below the advertised guide (53 per cent) than above (37 per cent). In regional Victoria, that buyer-favourable trend is even more pronounced, with 71 per cent of properties failing to meet their price guides.

The structural floor

Despite the clear loss of momentum in the southeastern capitals, economists are stopping short of predicting a widespread market crash for the remainder of 2026. The broader residential market is supported by deep-seated fundamental structures, most notably an acute, chronic lack of housing supply.

Analyst Luc Redman of the REA Group said the combination of changes to capital gains tax, negative gearing and development investment would shape the market in ways that cannot entirely be anticipated.

“The Federal Budget is the most significant since the pandemic and changes to the capital gains discount, negative gearing and construction investment are expected to alter the current structure of Australia’s housing market.”

“In the short term, due to these changes, it is likely home prices soften slightly and rents increase marginally.

“The property market will likely see a gradual shift towards a higher proportion of owner-occupiers.

“The combination of these policies is not well understood in the public domain over the long term, though it is likely the incentives for new builds will support an increase in supply as much as construction and zoning constraints currently allow.

“That could be continued downward pressure on prices and rents, though the magnitude of this is likely to be slow and minimal as supply-side policy reform by the states isn’t expected to move significantly, even with a $2 billion enabling infrastructure incentive in front of them,” Mr Redman said.

While there are roughly 235,000 dwellings theoretically under construction nationwide, completions remain severely bottlenecked by prolonged supply chain frictions and widespread labour shortages within the construction sector. At the same time, the national rental crunch shows no signs of abating, with the national vacancy rate locked at a critical 1.7 per cent.

Ultimately, while structural undersupply and tight rental markets are guaranteed to maintain a solid floor under Australian property values, the era of uniform, nationwide capital gains is officially on pause.

For strategic investors, the 2026 landscape could require looking past the national averages and identifying the localised trends dictating a highly fragmented market.
