House Price Change 10 Years (Nominal) in Finland compared to Europe
Finland publishes good house price and rent statistics. The best source is Statistics Finland, though some longer time-series are in Finnish (asuntojen hintakehitys = dwelling price changes).
The Institute for Real Estate Economics has The Finnish Property Monthly, Quarterly and Annual reports. The Bank of Finland is a third good source (see statistics | prices and costs | domestic asset prices).
