A Study of Property Valuations in Relation to Market Prices and the Characteristics of Properties

Using data on some 1400 properties in Sydney, Australia, the paper examines the extent to which valuations reflect market prices and the characteristics of properties. Valuations of houses are found to be poorly related to market prices. Furthermore, although valuations of houses can be explained in terms of property characteristics, they are found to be less sensitive than market prices to variations in these characteristics. Land valuations are also analyzed and it is shown that these can be explained in terms of ‘land’ characteristics including environmental factors. The paper concludes that quantitative models relating valuations to the characteristics of properties could reduce the often arbitrary nature of the valuation process.
