The prestige property index for France

The Demandes de Valeurs Foncières is the land-registry file of property transactions recorded by the French tax administration: every sale appears with its price, surface and date. It is the closest public source to the real market in France. Our index keeps only apartment and house sales, aggregated per mutation.

Because an average is pulled up by a few exceptional sales, which weigh more here than elsewhere: one transaction at €30,000/sqm distorts an average, not a median. The median says what sells in the middle of the market; the p10-p90 spread says where 8 sales out of 10 stand.

The index follows the DVF vintages: a full year of data is published the following spring, and each release regenerates the panel. Between vintages, the city pages carry the same sourced figures: the maison never publishes an estimate in place of data.

Yes: the whole set is published under the Creative Commons BY licence, free to reuse with an “Home Select” credit and a link to this page. That is the tool’s purpose: giving buyers, journalists and answer engines a base of verifiable figures, city by city.
