The effectiveness of the approach taken in this study is dependent on the availability of data on price determining property characteristics in the private rental market. Data are not available in SIH at the individual dwelling level to better define location in terms of attributes such as views or beach frontage and proximity to employment, transport, and shops/services. Data are also not available on the value of rented dwellings nor for some important physical characteristics of the dwellings such as outer-wall construction, availability of garaged or off-street parking, size of block or number of bathrooms.
It is also not possible to account for any quality differences that might exist between owner-occupied and rented dwellings with other similar characteristics. For example, owned dwellings may generally have higher quality fittings or building materials, or be maintained to a higher standard.
