The street as the VERA PI databases hold it: the home sales of DGFiP's DVF register from January 2021 to June 2026 (a deed of one house or flat; geo-dvf, Etalab, and DGFiP's file of 12 October 2026), the parcels of the cadastre and the addresses of the Base Adresse Nationale. A median needs ten sales. Never a single sale, never an owner. Read 2026-10-19.
