Apartment Price Indices on the Example of Cooperative Apartments Sale Transactions

The article presents the review of methods used to construct apartment price indices in order to select a method of determining a price index for a chosen local apartment market in the West Pomeranian Province. The analysis covered 369 free-market sale transactions of cooperative apartments that had been concluded from 4 May 2000 to 18 August 2010 by a Housing Cooperative in the Zachód development in Stargard Szczeciński with the total number of 2,712 flats (constituting a stable and homogenous housing resource due to the time and technology of construction). To each transaction seven features have been attributed: a transaction date, a sale price, a property size, an address, a number of rooms, a floor and the number of floors in a building. The above considerations confirm the usefulness of classic indices of apartment price dynamics on a spatially limited market where it is possible to differentiate sets of apartments that are considered homogenous because of the similarity of their primary characteristics.
