The dip investors have been waiting for: what Deloitte's supply warning really means

When headlines report falling home values, two very different readers see two very different things. One sees a market turning against them. The other sees a narrowing window of opportunity.

New analysis from Deloitte Access Economics makes the case for the opportunity reader. Values have eased, but not one of the pressures that drove them up over the past decade has been resolved. What has changed is the price, not the fundamentals.

The report found that houses continued to outperform units, with regional areas also maintaining strong profit results. While nearly all capital cities recorded high levels of profitable sales, standout results were seen in Perth and Adelaide, where resale conditions remained particularly strong. 

For homeowners and investors, this trend highlights the equity-building potential of property in the current market environment.

What the dip actually is

Cotality's national Home Value Index fell 0.4 per cent in June, its steepest monthly decline since December 2022. Sydney gave up 1.2 per cent and Melbourne 1 per cent. Darwin, Perth and Brisbane all still rose, at 1.4, 0.7 and 0.3 per cent.

The state picture is where the real story sits, and it is not one market at all. Over the year to May, dwelling values across Western Australia rose 25.8 per cent in Perth and 22.7 per cent across the rest of the state. Queensland recorded 19.1 per cent in Brisbane and 14.7 per cent through regional Queensland. South Australia posted 12.3 and 11.1 per cent, Tasmania 9.3 and 11.8 per cent.

Set that against the two markets driving the national headline. Sydney managed 2.3 per cent for the year while regional New South Wales gained 8.7 per cent. Melbourne rose 0.5 per cent against 7.8 per cent across regional Victoria.

Two conclusions follow. The first is that a national average is disguising a spread of roughly 25 percentage points between the strongest and weakest markets. The second is that in every state the regions outperformed the capital, except in the three markets that had already run hardest. Combined regional values rose 0.3 per cent in June while the combined capitals fell.

Now the number that rarely makes the headline. National dwelling values remain 7.3 per cent higher than a year ago.

Deloitte partner Stephen Smith and economist Dan Kelly put the softening down to two forces landing together: tighter monetary policy, and investors reacting to the Federal Budget's tax changes targeting demand for established property. Their read is that this is a short-term story, and that supply constraints will keep upward pressure on prices over the medium term.

Treasury's modelling points the same way. Its estimate is that the Budget's tax reforms will trim about two percentage points from house price growth over the next year or two. That is a slower climb, not a decline.

The shortage is not going anywhere

Here is the part that matters most for anyone thinking in decades rather than quarters.

Residential building approvals rose 16.6 per cent over the year to May on a rolling 12-month basis, according to the ABS. Encouraging, until you look at what it adds to: around 203,000 approved dwellings. Australia needs roughly 240,000 approvals and completions a year to meet the National Housing Accord target of 1.2 million homes over five years.

Approvals are also a long way from keys in a door. Deloitte's figures show the average number of houses approved but not yet started climbed to about 12,100 over the year to March 2026, an 8 per cent increase on three years earlier. Building costs, trade shortages, finance pressure and delays are combining to strand projects that have already cleared planning.

Cotality's own read is the same. Elevated construction costs and feasibility problems continue to limit housing delivery, and where approvals and commencements have lifted, that has yet to translate into a meaningful rise in completions.

The apartment pipeline looks healthier only until you ask why. The queue of approved non-house dwellings waiting to commence has shrunk, but Deloitte attributes that to fewer projects being approved rather than builders clearing a backlog.

The part that works in favour of existing owners

There is a feedback loop in this that deserves more attention than it gets.

New projects generally need strong off-the-plan sales to secure finance and start construction. Buyers commit to those sales when they expect values to rise. Soften that expectation and pre-sales dry up, finance does not close, and the project stalls.

So the measures cooling the market this year are quietly removing homes from the pipeline that would have eased pressure in three or four years' time. Anyone waiting on the sidelines for a better entry price is, in effect, waiting for a shortage to get worse. Anyone already holding well-located stock is on the other side of that equation.

Rental markets are already showing the strain. The national vacancy rate sat at 1.5 per cent in May, matching the record lows of 2022 and 2023, with annual rent growth running at 5.9 per cent.

Rates come and go

Interest rates are a cycle, not a ceiling. Deloitte's view is that they will not suppress values indefinitely: once inflation is under control, rates come down, borrowing capacity is restored and confidence follows it back into the market. Treasury expects the drag from the tax changes to fade to something modest over the longer run. Both are temporary conditions dressed up as permanent ones.

What is not temporary is the arithmetic underneath. Australia approves fewer homes than its population needs, year after year, and a growing share of what does get approved never gets built at all. Rates will move. That gap has not closed in a decade and nothing in the current pipeline suggests it closes in the next one.

The long view

None of this is new. Cotality's long-run series on capital city values shows the pattern repeating across more than four decades, with periods of flat or falling growth folded into a long-term average of roughly 7 per cent a year. Every one of those slowdowns felt significant while it was happening. Almost none of them looks significant on the chart now.

The five-year figures make the same point more bluntly. Perth values are 91.4 per cent higher than they were in May 2021 and regional Western Australia is up 93.3 per cent, while Melbourne has gained 3.3 per cent over the same period. Anyone reading a national average in 2021 would have learned nothing useful about either.

Nobody buys at the exact bottom, and the investors who do best rarely try. What separates them is rarely better timing. It is a longer holding period than the cycle they bought into, a decision anchored to supply and to the specific market rather than to national sentiment, and a willingness to act while others are still waiting for confirmation that never arrives in time to be useful.

The market rewards time held far more reliably than it rewards time spent waiting.
