Sources and method
- Apartment prices: Statistics Finland, prices of housing company apartments (StatFin 13mt). Updated 17 August 2026. The average price per m² is a sales-weighted average of completed sales over the last four quarters, shown only if there are at least 6 sales.
- Detached house prices: National Land Survey of Finland, register of property prices (detached house properties, built plots). Updated 28 October 2026. The average price is a sales-weighted average of completed sales over the last 3 years, shown only if there are at least 8 sales. The figure is the total property price: the register has no floor area for the building, so no price per m² is calculated.
- Population, income and education: Statistics Finland, Paavo: open data by postcode area (12f7). Statistical year 2024.
- Limitations: the figures are area averages. They do not tell you the value of an individual apartment and are not investment advice. In areas with few sales a single sale moves the average.
