A vacancy rate is the percentage of rental properties in a suburb or market that are currently unoccupied. It is one of the most important indicators for property investors because it tells you whether demand for rentals is strong or weak — and whether you are likely to find a tenant quickly and at a good rent.
What Is a Healthy Vacancy Rate in Australia?
A vacancy rate below 2% is considered tight — meaning strong rental demand, low time on market and upward pressure on rents. A vacancy rate above 3% signals a softer rental market where landlords may need to offer incentives or accept lower rents to secure tenants. According to SQM Research, the national vacancy rate in early 2026 sits at approximately 1.1% — near historic lows — driven by chronic undersupply across most Australian capital cities.
How Do I Use Vacancy Rates to Pick a Suburb?
Investors use vacancy rates alongside gross yield and median rent to assess rental demand. A suburb with a vacancy rate below 1.5%, a gross yield above 4% and rising median rents is a strong indicator of a healthy investment market. Suburbs with consistently low vacancy rates include inner-north Melbourne (Northcote, Preston, Thornbury), inner-west Sydney and much of Brisbane’s inner ring.
Where Do I Find Vacancy Rate Data?
SQM Research publishes monthly vacancy rate data by suburb and postcode. You can also track vacancy rates through CoreLogic, Domain and REA Group’s rental demand reports. The GeeVee platform aggregates this data alongside rental yield, price growth and infrastructure signals for every suburb in the Collings coverage area.

Frequently Asked Questions
What does a 0% vacancy rate mean?
A 0% vacancy rate means every rental property in the area is currently occupied. This is extremely rare and indicates an acute shortage of rental supply relative to demand — typically a very strong signal for investors.
What vacancy rate should I avoid as an investor?
A vacancy rate above 3% is a warning sign. Rates above 5% indicate a significantly oversupplied rental market where finding tenants at your target rent may be difficult and extended vacancy periods can erode your returns.
Do vacancy rates predict capital growth?
Not directly — but persistently low vacancy rates often precede rental price increases, which in turn support capital growth. Tight rental markets signal strong underlying demand for housing in the area, which is a positive medium-term capital growth signal.
How does GeeVee use vacancy rates?
GeeVee incorporates vacancy rate data from SQM Research into its suburb investment scoring model — weighting it alongside rental yield, price growth trajectory, infrastructure investment and population growth signals to produce an overall Investment Score for every suburb it covers.
