How Many Investment Properties Do Australians Actually Own? (And Why It Matters for Prices)
About 2.27 million Australians held an interest in a residential investment property in 2021–22, according to the Australian Taxation Office (ATO, 2021–22). Roughly 70% of them own just a single rental property — yet investors who hold multiple properties collectively own close to half of all investment housing, and only around 20,000 own six or more (RBA, 2026; ATO, 2020–21). Ownership is far more concentrated than the headline investor count suggests, and that concentration sits at the margin of the market — the part that does much of the work in setting prices. These are point-in-time figures and context for households thinking about how their wealth is held, not a prediction about where prices will go.
How many Australians own an investment property?
On the most recent ATO Taxation Statistics, about 2.27 million individuals reported an ownership interest in a rental property in 2021–22 (ATO, 2021–22). That is roughly 14% of Australia's taxpayers, and on a broader measure close to one in five adults own an investment property (ATO, 2021–22; Housing Australia, 2026). Investor numbers actually fell slightly in 2022–23 — only the third annual decline in 25 years (RBA, 2026) — so the pool of investors is large but no longer growing automatically each year. These are tax-reporting figures, capturing individuals who reported rental income in the relevant year rather than every beneficial owner.
How concentrated is investment property ownership?
Most investors are small. Applying the ATO's 2020–21 ownership distribution to the 2.27 million investor base gives an approximate picture (ATO, 2020–21):
about 71% own one property — roughly 1.62 million investors;
about 19% own two — roughly 430,000 investors;
the remaining tenth own three or more, and the numbers thin quickly from there;
only about 0.9% — roughly 20,000 investors — own six or more.
The Reserve Bank's analysis of new investor data tells the same story from the other direction: around 70% of investors own a single property, but investors with multiple properties together own close to half of all investment housing (RBA, 2026). A large group of one-property landlords sits alongside a much smaller group that controls a disproportionate share of the stock. Because about nine in ten investors own only one or two properties, reforms aimed at investors with larger portfolios — a negative-gearing cap set above two properties, for example — would, on this distribution, reach only a small minority of the investor base.
Why does a small group of investors matter for prices?
Because housing supply adjusts slowly, prices respond most to the change in demand at the margin, against a near-fixed stock — not to the total number of owners. A concentrated, multiple-property cohort is an outsized part of that active margin: when their incentives to buy or sell shift — through interest rates, credit conditions, or changes to tax settings such as negative gearing, the Division 296 super tax, or the ban on new SMSF residential-property borrowing — the effect on prices can be larger than the size of the group implies. It is the same marginal-flow mechanism that explains how a small change in demand can move house prices far more in supply-constrained markets. Ownership concentration is one factor among many — alongside interest rates, construction and credit — and is planning context, not a market call in either direction.
What this means for protecting wealth held in property
For the households inside these statistics — particularly the minority who own several properties — the practical question is not which way the market will move, but what happens if the income behind the loans suddenly stops. Christopher Hall, AdvDipFP, Authorised Representative, AFSL 526688, has completed more than 500 life insurance policy reviews for Australian families. In his experience, investors with wealth concentrated across one to several geared properties frequently underestimate the liquidity risk that illiquidity creates: a property cannot be partially sold, so if an owner dies or can no longer work, the family can be forced to sell under pressure rather than on their own timetable.
That is the risk life, total and permanent disability (TPD) and income protection cover is built to answer. The proceeds can clear or service the debt and replace lost income, so a concentrated property position can be kept rather than sold at the wrong moment — independent of which way the market is moving. It is the same forced-sale risk that sits behind whether too much of a household's wealth is tied up in property, and it forms part of the wider property, mortgage and protection planning picture. Households in this position may wish to speak with a specialist life insurance adviser about their individual circumstances.
Frequently Asked Questions
How many investment properties do Australians own?
About 2.27 million Australians held an interest in a residential investment property in 2021–22 (ATO, 2021–22). Around 70% own a single rental property, while investors holding multiple properties together own close to half of all investment housing (RBA, 2026). Ownership is large in number but concentrated in who holds the most.
How many property investors are there in Australia?
On ATO Taxation Statistics, roughly 2.27 million individuals reported an ownership interest in a rental property in 2021–22 — about 14% of taxpayers (ATO, 2021–22). Investor numbers fell slightly in 2022–23, only the third annual decline in 25 years (RBA, 2026).
What share of investors own more than one property?
About three in ten. On the ATO's 2020–21 distribution, roughly 71% of investors own one property and about 19% own two, leaving around a tenth who own three or more (ATO, 2020–21). The Reserve Bank reports a similar split of about 70% holding a single property (RBA, 2026).
How many Australians own six or more investment properties?
Roughly 20,000. On the ATO's 2020–21 ownership distribution, about 0.9% of investors — approximately 20,000 people when applied to the 2.27 million investor base — own six or more properties (ATO, 2020–21; 2021–22). It is a very small fraction of all investors.
Do a small number of investors own most of Australia's investment housing?
The minority of investors who own multiple properties together hold close to half of all investment housing, even though about 70% of investors own only one (RBA, 2026). So a relatively small group accounts for a disproportionate share of the stock, while most landlords are single-property owners.
Why does property investor concentration matter for house prices?
Because housing supply adjusts slowly, prices respond most to demand at the margin against a near-fixed stock. A concentrated, multiple-property cohort is an outsized part of that margin, so a shift in their incentives can affect prices more than the group's size suggests. It is one driver among several — interest rates, credit and construction also matter — and not a forecast.
Book a quick review with an adviser
Book a quick review with an adviser now. For households whose wealth is concentrated in one or more properties, a review of life, TPD and income protection cover checks whether the cover in place is enough to clear or service the debt if an owner dies or can no longer work — so the property need not be sold under pressure, whatever the market is doing.
