Prices of dwellings in housing companies: Errors in the source data of the statistics have been corrected

Description of the correction

Erroneous data in the statistics on prices of dwellings in housing companies were corrected on 10 November 2026. There was an error in the source data of the statistics, for which reason dwelling transactions were missing. The errors concerned the numbers of transactions and selling times of old dwellings in housing companies made through real estate agents in January to September 2026. The effect of the error on the price index of new dwellings and numbers of transactions is so low that they will not be revised.

Effect of the corrections on numbers of transactions

Altogether 9.2 per cent more transactions of old dwellings were added to the data for January to September. The data were supplemented least for the months in the early part of the year and most for September.

The numbers of transactions of old dwellings in housing companies made through real estate agents increased on the level of the whole country by

• 0.9 per cent in January
• 3.4 per cent in February
• 7.2 per cent in March
• around 11 per cent in April to August
• 14.7 per cent in September.

Effect of corrections on selling times

The data error also had an effect on the selling times of old dwellings sold through real estate agents. The selling times shortened on the monthly level by around one to nine per cent in January to August. In September, the selling times lengthened by close on one per cent.
