The average price is in euros per property and the number of sales is a count. The register has no floor area for the building, so a price per m² cannot be calculated and the figures are not standardised for house size: large and small houses share the same average. Sales of detached houses on leased plots are not property sales, so they are missing from the register entirely. Year 2026* is still in progress and will be completed later, so it is left out of the annual change.
