Primary and Secondary Residential Real Estate Markets in Poland – Analogies in Offer and Transaction Price Development

The paper presents the results of a comparison of the development of mean offer and transaction prices per 1m2 in primary and secondary residential real estate markets in 16 provincial capital cities in Poland, during the time period from the 3rd quarter of 2006 to the 3rd quarter of 2012. The quarterly data came from the residential real estate price database of the National Bank of Poland (NBP). The research concerns the dependencies in the residential real estate market between the following four price categories: offer prices in the primary market, transaction prices in the primary market, offer prices in the secondary market and transaction prices in the secondary market. For each city, the dynamics of each price category per 1m2, the existence of a linear correlation between the individual mean price categories in chosen subintervals and their convergence and variability in time were studied and compared.
