The plot as the VERA PI databases hold it: the parcel and its area in DGFiP's cadastre, its addresses in the Base Adresse Nationale, the home sales of DGFiP's DVF register around it from January 2021 to June 2026 (a deed of one house or flat). A median needs ten sales. Never a single sale – not even the plot's own – never an owner. Read 2026-10-19.
