Housing Stock: Investment in residential rental property
In 1993, three-quarters of a million people were investors in residential rental property. 78% of these people invested in only one rental property.
The supply of rental housing has been left largely to market forces1. This has not always resulted in an adequate supply of affordable private rental dwellings, particularly for low and moderate income earners. Investment by individuals in residential rental property has a significant impact on rental housing supply and subsequently affects the demand for public housing

Respondents were asked how many residential rental properties they owned. Each respondent was then asked to provide data for their most recently acquired properties up to a maximum of three. Therefore, for one-parent and one-person income units, data were collected for up to three properties and for couple income units, up to six properties. Data in this diagram relate to each income unit's ownership of these properties.
INTRODUCTION
The private rental market in Australia provided housing for approximately 20% of Australian households in 1995-96. It was the second largest source of housing after home ownership. In size, the private rental market far outweighed the public housing sector which accommodated 6% of Australian households (Housing Occupancy and Costs, Australia, 1995-96 (Cat. no. 4130.0)).
Then I get a bit lost, but someone might get the hang of this:
Rental Investors Survey
The Rental Investors Survey (RIN) was conducted in 1997 (and in 1993 as the Investors in Rental Dwellings Survey). It collected information on the demographic characteristics and economic resources of people who invest in residential rental property in Australia, and the physical characteristics of their most recently acquired properties.
More information on the RIN is included in the Directory of Statistical Sources.
Information from the RIN is available in a publication and as a Confidentialised Unit Record File. Customised tables can also be produced on request to meet individual user needs (standard consultancy rates are charged). For further information, contact the National Information and Referral Service.
