Why vacancy under 1% matters more than the next rate call.

Ask a room full of investors what they’re watching and you’ll hear the same answer: the next RBA meeting. Rates dominate the headlines, the dinner-party conversations and the doubts. And they matter — the cash rate sets the cost of the money you borrow.

But the cost of money is only half of the investment equation. The other half is what the asset does once you own it — whether it rents quickly, holds its tenant, and grows its income. That side of the ledger is governed by a quieter number that rarely makes the front page: the vacancy rate. And right now it is telling a louder story than the RBA is.

The vacancy rate is the share of rental properties in a market sitting empty and available at a point in time. Around 3% is considered balanced: tenants have reasonable choice, landlords face reasonable competition, and rents track broadly sideways in real terms.

Below 1%, the market is something else entirely. There is functionally nothing to rent. Properties lease in days, often to queues of applicants, and rents are set by scarcity rather than negotiation. Here is where Australia’s capitals stood at the last reading:

Vacancy is not an abstract statistic. It flows directly into the three things that determine whether a property pays its way.

Here is the distinction that matters. Interest rates are cyclical: they rise, they fall, and every move is broadcast, priced in and argued about by economists on both sides. Whatever the RBA does at its next meeting, it will eventually do something different at a later one.

Housing scarcity is different. It is the product of a decade of under-building colliding with record population growth, a construction industry at capacity, and approval pipelines that take years to convert into keys in doors. None of that reverses because of a 25-basis-point move in either direction. A rate cut does not build a single home — if anything, it adds buyers and tenants to a market that already cannot house them.

“Everyone asks me where rates are heading. Almost nobody asks where the tenants are going to live. When vacancy is under one percent, the second question is the one that pays you.”

— Bradley Wearne, Meridian Australia

That is why the vacancy chart above deserves more of your attention than the next rate decision. It describes conditions that will still be shaping returns years after the current rate cycle is forgotten.

The lesson is not that rates are irrelevant — serviceability and holding costs always matter. The lesson is about weighting. A well-selected property in a critically tight rental market keeps performing through rate rises, rate cuts and everything in between, because its performance is anchored to scarcity rather than sentiment.

It is also why suburb selection matters more than timing. Vacancy is not uniform within a city: the Meridian research model screens markets suburb by suburb for the drivers behind the headline number — supply pipelines, land availability, population growth and tenant depth — before a property is ever shortlisted.

If your next purchase is anchored to a market where almost nothing sits empty, the next rate call becomes what it should be: a detail in the plan, not the plan itself.
