Perth’s housing market has two stories running at once, and they point in opposite directions. Prices are retreating after several years of rapid gains. Yet the rental vacancy rate across Western Australia sits at just 0.6 per cent, and around 64,000 new residents arrived in the twelve months to March 2026.
That tension is the real Perth property market forecast question. It is not whether the bottom has arrived. It is which pressure lasts longer: the squeeze on borrowing, or the shortage of homes.
Weak demand is coming from the wallet, not the headcount
People are still moving to WA. What has changed is how much they can borrow. Higher repayments and tighter household budgets cut the size of loan a bank will approve, and that caps what buyers can bid, regardless of how many of them there are.
The national signal is stark. After the federal budget, one major bank recorded a 30 per cent drop in first home buyer mortgage applications and a 26 per cent drop in investor applications. Fewer applications today means fewer settlements later, and fewer buyers competing at the next auction.
If you want the mechanics of why repayments bite so hard, our guide to RBA interest rates and mortgage repayments walks through it in plain English.
Key numbers
- About 64,000 new WA residents in the twelve months to March 2026
- Rental vacancy of 0.6 per cent
- Mortgage applications down 30 per cent (first home buyers) and 26 per cent (investors) after the budget, per one major bank
- One major bank expects national values to fall about 7 per cent from their peak
Why this is not a repeat of the 2014 to 2019 slump
The last Perth downturn came with a wave of people leaving for the eastern states and a glut of new stock. Neither is present now. Population is growing, and the construction shortfall, while narrower than it was in 2023, has not closed.
That difference matters for how long prices stay soft. A market with too many homes needs years to absorb them. A market with too few homes mostly needs buyers to regain their borrowing power. Those are different problems with different timelines.
What a flat base case really means
A demand index puts its central scenario at Perth’s median house price holding near current levels until September 2028. Its alternatives range from further falls to renewed growth.
Treat that as a range, not a promise. A flat price for roughly two more years is a perfectly reasonable outcome when the downward and upward forces roughly cancel. For anyone holding, it means a long stretch of no capital gain, not a collapse.
The national lender’s own view is a modest recovery in 2027, then a stronger one the year after. Notice the gap between that and the index: one sees growth returning sooner, the other sees a plateau. Both can be right if the recovery is slow and patchy.
The catch in the supply argument
Undersupply is real, but it is not a trigger. Scarcity supports prices over years. It does not stop them falling in the meantime if buyers cannot get finance. Tight rentals can also push more people toward buying, but only if they can pass a serviceability test.
That is why the policy debate matters. Subsidising construction costs lifts supply, while first home buyer grants lift demand into a market that is already short of stock. Different tools, different side effects. See how similar forces are playing out elsewhere in our look at Perth house prices falling at a record pace after an 82 per cent run.
What it means for readers
Don’t try to call the bottom. Nobody gets that right on purpose, and a flat market punishes impatience less than it punishes overstretching.
- Buyers: Get pre-approval and stress-test your repayments at a higher rate. If your budget only works at today’s rate, it does not work.
- Investors: Tight vacancy supports rents, but check your cashflow buffer before you lean on capital growth.
- Owners: A flat price is not a loss if you are not forced to sell. Avoid decisions made out of fear.
- Renters: Low vacancy suggests competition for homes will stay fierce, so budget for rent that holds firm.
The practical next step: work out your maximum comfortable repayment now, then see what loan size that supports. That number, not a price forecast, tells you whether you can act.
