ProofPrice returns the published average for the newest period that has a price, unchanged. Statistics Finland says average prices per square metre describe regional differences in price levels and should not be used to calculate price change, so no change is calculated: the quarterly answer carries the published price-index changes, and the other tables carry none. For a postal code, flats are published by number of rooms with no total, so the answer is the room size with most transactions and the others are listed. No range is calculated: only one average and the number of transactions are published.",

Statistics Finland's price index for these dwellings (a quality-adjusted measure, not this average) is 0.3% lower than in the first quarter of 2026 and 4.3% lower than a year earlier (the second quarter of 2025).
