Owner-Occupier Ratio
The share of homes in a suburb lived in by their owner rather than rented out.
What it is
The owner-occupier ratio is the percentage of dwellings in a suburb where the resident owns the home, outright or with a mortgage, rather than renting it.
Nationally, 67% of Australia's 9.8 million households own their home and 31% rent. A suburb sitting at 45% is well below the norm, which is a flag to investigate rather than a verdict.

Why it matters
Low ratio
under 50%
- Investor and tenant heavy
- CBD, student or mining areas
- The result = softer price support
High ratio
70% and over
- Owner-dominated and tightly held
- Long-term residents, low turnover
- The result = stable, with strong growth support
What counts as high, what counts as low
Shaded from a buyer's point of view: teal is favourable if you are buying, amber is balanced, red is harder. That is why this looks inverted against some other metrics, because a fast-moving market is good for a seller and hard for a buyer.

The trend to watch for
This is a supply-side metric, not a demand one. A high ratio means less rental supply, which helps a landlord, but it is not itself evidence of demand. Always read it next to the vacancy rate.
A reading around 65% to 70% can also be a sell signal, because it often marks the point of peak emotional buy-in.
What it looks like in the real world
Low ratio
under 50%
- CBD apartment or short-stay precinct
- University suburb with annual tenant churn
- Mining or fly-in fly-out town
High ratio
70% and over
- Established family suburb with long-term residents
- Coastal or retiree hold market
- New owner-occupier estate
