How this is calculated
Illustrative path: today's asking price is rebased with the named official source's transaction-price index for existing homes. It is not this property's price history or a valuation.
Official national house-price index for purchases of existing dwellings, all dwelling types together; it is country-level context, not a commune or apartment/house index. Quarters flagged provisional or estimated by Eurostat may be revised.
