Rate Hike Slashes First‑Home Borrowing Power as Sydney‑Melbourne Prices Slip

*TL;DR: The Reserve Bank’s third straight rate increase trims a typical first‑home loan by about $17,000, outpacing the 0.6%‑0.9% fall in Sydney‑Melbourne house prices and deepening the affordability gap.*

Context The Reserve Bank of Australia (RBA) raised the cash rate for the third month in a row, a move aimed at cooling inflation. Higher rates raise mortgage repayments, which in turn dampen demand for property. Sydney and Melbourne have seen their median house values dip modestly in April, but the impact on buyers’ borrowing power is far larger.

Key Facts - Sydney home values fell 0.6% in April and are down 0.9% over the past three months; Melbourne prices slipped 0.9% in April and 1.5% over three months. - The cheapest 25% of homes, where most first‑time buyers look, rose 1.5% in Sydney and 0.5% in Melbourne during the same period. - An average first‑home loan stands at $607,000. With a typical household income of $106,000, each RBA rate hike reduces borrowing capacity by roughly $17,000. - The government’s deposit guarantee scheme now allows a 5% deposit, but higher prices in the low‑cost segment erode the scheme’s benefit. - Westpac’s consumer survey shows two‑thirds of Australians still expect prices to rise, despite the recent declines. - In contrast, Perth and Brisbane continue to see price gains, with Perth up 9.2% year‑to‑date.

What It Means For prospective buyers like 24‑year‑old Dani Hunterford, the combined effect of falling prices and shrinking loan limits is a widening gap between rent and purchase. Even as median values retreat, the segment most accessible to first‑time buyers is appreciating, meaning the “affordability glimmer” is largely illusory. Gerard Burg of Cotality notes that the $17,000 reduction in borrowing power could be the decisive factor between securing a property and remaining a renter.

Potential buyers can mitigate the squeeze by improving credit scores, reducing credit‑card debt, and shopping for lower mortgage rates. However, the fundamental stress test—whether future rate hikes can be absorbed—remains a hurdle.

Looking Ahead Watch the RBA’s next policy decision and its ripple through mortgage rates, as well as any shift in the deposit guarantee scheme that could alter the calculus for first‑home seekers.
