Housing prices in the primary and secondary markets, offer prices, trans-action prices and hedonic prices relies on data from a housing market survey of the Real Estate Market Database (BaRN). As part of the new survey of commercial real estate, Commercial Real Estate Market Database (BaNK) data on rent, offer prices and transaction prices of commercial real estate are collected.
The data for the new and existing market presents the average prices per square meter of housing, both offer and transaction, for the 16 capital cities of voivodeships and Trójmiasto. Also the average prices for the 7 and 10 cities, weighted with the market housing stock of the city, are shown.
The hedonic price of housing reflects the "pure" price, that is the price that results from other factors than the quality of hous-ing. In this study, the hedonic price is an average price from the base period multiplied by the hedonic index. The price re-flects an average level of prices of a specific housing samples from the base period (a fixed housing basket), after inclusion of the "pure" change in price of homes sold in consecutive periods. The hedonic price stated in the report says what the average price of the fixed home sample from a specific reference period would be, considering the real "pure" change in transaction prices. The difference between the hedonic index used to determine the hedonic price and the average or the median price growth is that the index does not react strongly to any change in the quality of homes sold over a certain period, (for instance the hedonic index should respond less to a larger number of small apartments with a higher price per square meter than the average or median price index).
