Created by the Institute IMARS the real estate price ranking in cities allows to compare current as well as historical real estate prices. It shows also the dynamics in the largest cities. We monitor the largest cities in the Silesian Voivodship in three basic segments of the housing market like apartments, housing estates and land for houses. The Price Ranking, as well as the Real Estate Barometer, is updated automatically, on the basis of the transactions data accumulated in the Data Base, managed by the Institute. There are around 10.000 records based on deeds introduced to the Data Base every quarter.
