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.

The count is published even for quarters with no published average price, so the chart also shows apartment types with few sales. The last quarter (Q1/26*) is preliminary, hence lighter.
