Average house prices usually differ across regions. Spatial variation in residential property prices can be attributed to social, economic and historical characteristics of regional marekts. Moreover, existing studies do not provide strong evidence for convergence of house price levels in regional dimension. The lack of price level convergence, however, does not exclude convergence in terms of price dynamics. 

The paper tries to answer the question whether price trajectories on regional housing markets in Poland show long-term similarity. Using quarterly data covering the period of 2003-2017, the panel unit root testing has been conducted on relative prices across sixteen regional housing markets.
