Rental vacancy at 1.6%: the squeeze on FHB savers

Every month spent renting in 2026 costs more than the month before. Cotality's April data, analysed by MacroBusiness this week, shows Australia's national rental vacancy rate sitting at just 1.6% - well below the 2.5% to 3.3% considered a balanced market. At the same time, advertised rents are rising at 5.7% per year. For first home buyers still saving a deposit, this creates a compounding problem: the cost of waiting is rising in both directions.

What the April 2026 rental data shows

Cotality's latest housing data paints a clear picture of a rental market under sustained pressure. Every capital city recorded a vacancy rate of 1.8% or lower in April 2026. Not one has returned to the historical norm that typically gives tenants meaningful negotiating power. MacroBusiness noted there is "no evidence that the rental market is starting to loosen."

The key numbers from the April 2026 Cotality data:

• National vacancy rate: 1.6% in April 2026, against a decade average of 2.5% to 3.3%
• Rent growth: Advertised rents rose 5.7% in the year to April 2026
• Income share: Australian renters now spend a record 33.4% of pre-tax income on rent
• Sydney benchmark: A household needs approximately $143,000 gross income just to keep Sydney rent below the 30% affordability threshold

Without a significant increase in new housing supply or a stabilisation of population growth rates, rental pressures are likely to remain elevated throughout 2026. Net overseas migration is forecast to exceed 300,000 in this financial year, adding further demand pressure to a market already running short on supply.

Why CBRE expects the shortage to deepen through 2030

In its March 2026 Apartment Vacancy, Rent and Price Outlook, CBRE identified a structural supply gap that goes beyond a single cycle. Australia needs approximately 75,000 new apartments per year to keep pace with population growth. CBRE's construction forecast puts actual delivery at around 60,000 apartments per year between 2026 and 2030 - a gap of roughly 15,000 homes annually.

The consequence, CBRE forecasts, is a 27% increase in median apartment rents across capital cities by 2030. At current average rent levels, that trajectory would push a two-bedroom apartment toward approximately $825 per week - or roughly $42,900 per year - by the end of the decade.

Domain's Chief Residential Economist has noted that renters "have hit their limit" on affordability, meaning rent growth is now constrained by what people can actually pay rather than what landlords would prefer to charge. That is one moderating factor. But it also signals how far rents have already stretched relative to incomes.

What this means for first home buyers still saving

The rental squeeze has a direct effect on deposit-saving timelines. The more income that goes toward rent each month, the less goes toward savings. Fenro's 2026 housing affordability analysis found the average Australian takes approximately 11 years to save a 20% deposit on the median dwelling after accounting for rent and living expenses. In Sydney, that figure rises to 13.3 years.

There are practical steps that can change this calculation:

• Use the 5% deposit scheme: The First Home Guarantee now operates with no income caps and no annual place limit. Buying with a 5% deposit instead of 20% cuts the average savings timeline from 11 years to approximately 2 to 3 years - without paying Lenders Mortgage Insurance.
• Supercharge savings through super: The First Home Super Saver (FHSS) scheme lets you make voluntary contributions to super and withdraw them for your deposit. Contributions are taxed at 15% going in rather than your marginal income tax rate, which can add thousands to your deposit over a 2 to 3 year period.
• Stack available grants: First home buyers may be eligible to combine the First Home Guarantee with state grants - for example, Queensland's First Home Owner Grant remains at $30,000 for contracts signed before 1 July 2026, after which it drops to $15,000. Stacking grants can reduce the effective deposit gap significantly.
• Run a rent-versus-buy comparison: The break-even point between renting and buying shifts when rents are rising consistently. A tool that models your specific income, savings rate, local property price, and expected rent growth will give you a more accurate picture than general rules of thumb.

None of this means rushing into a purchase that does not fit your financial position. A mortgage broker or financial adviser can help you assess your specific circumstances in detail. But the data does suggest that the cost of continuing to rent is rising - and that understanding the gap between your current path and an alternative is a useful exercise right now.
