Is renting actually cheaper than buying right now? Perth's affordability math just shifted

For years, Perth renters have clung to a simple argument: throwing money at landlords beats drowning in a mortgage. In 2026, that logic is crumbling faster than a Northbridge weatherboard.

The numbers tell a stark story. A median Perth house now sits around $680,000. On a 25-year loan at current rates hovering near 4.3 per cent, that translates to roughly $3,500 monthly repayments—before rates, insurance and maintenance. Meanwhile, a comparable three-bedroom in sought-after suburbs like Subiaco or Mount Lawley is fetching $2,800 to $3,200 in weekly rent, or $1,200 to $1,386 monthly.

Superficially, renting wins. But dig deeper and the picture inverts.

With sub-1 per cent vacancy across greater Perth, landlords are raising rents aggressively. Properties that were $300 per week two years ago now command $380. Those annual increases—often 8 to 12 per cent—compound brutally over a decade. A buyer's mortgage, by contrast, stays fixed (if they lock in early). Property owners also pocket capital growth; Perth's fastest-growing suburbs around Joondalup and Wanneroo are seeing values climb 6 to 8 per cent annually, a tail wind renters never catch.

Consider tax and equity. Homeowners claim depreciation on investment properties; owner-occupiers build equity. Renters get neither. After ten years, our hypothetical buyer owns $250,000-plus in additional home value, assuming conservative growth. The renter? They've paid perhaps $180,000 in rent to someone else's deposit.

The RBA's recent messaging—rates may rise further before falling—clouds the picture. Higher borrowing costs hurt new buyers, but existing renters face the same squeeze without the equity shelter. Perth's historically tight rental market means landlords have pricing power renters simply lack.

It's worth noting the counterarguments. Buyers face maintenance shocks (a burst pipe in Cottesloe costs real money), rates rises could sting faster than rent, and market downturns are possible. Renters enjoy flexibility—crucial if your career shifts between Canning Vale and the CBD.

Yet for middle-income earners planning to stay in Perth beyond five years, the equation has tipped decisively toward ownership. The gap between rent and mortgage payments has narrowed to almost nothing, while the long-term wealth creation diverges dramatically. In a market where finding a rental is harder than buying, that shift matters profoundly.
