An Unobserved Components Approach to Separating Land from Structure in Property Prices: A Case Study for the City of Brisbane

The study develops a spatio-temporal model of hedonic pricing that explicitly separates the land and the structure components of property prices. This is illustrated with a dataset for Brisbane, Australia, constructed by combining commercial real estate, local government databases and GIS-based spatial analyzes. The land component of prices has increased from 42% in 2000 to 66% in 2010. This has implications for a broad range of planning and policy issues, including property tax rates, town planning, and options for climate adaptations.
