People in France can access official data showing recent property sale prices for homes and land in their area using a free government tool that draws on the past five years of transactions.
The ‘Demande de valeurs foncières (DVF)’ tool is available online via the French government’s open data platform. It allows users to explore recorded property sales across most of France and review what nearby properties have actually sold for in recent years.

Access is free, and the tool can be used to help track local property price trends or to estimate a potential value range for a home or plot of land by comparing it with similar nearby transactions.
The underlying DVF dataset is generally refreshed every six months, in April and October, incorporating the latest available notarial sales data.
Results are displayed through an interactive map interface, showing individual transactions with details such as sale price, date of sale, and property type (flats, houses, commercial premises, or undeveloped land).
Where available, listings may also include descriptive information such as surface area, number of rooms, and other basic property characteristics.
A visual layer shows relative price levels geographically, with lower values typically highlighted in green and higher values in red.
How to use the DVF map
Users can search the tool in several ways:
Search bar: Enter a full or partial address directly.
Filters: Select property types such as flats, houses, commercial premises, or land.
Map navigation: Zoom into a department, then a commune, and finally a cadastral section.
Plots of land that have been involved in at least one recorded transaction are highlighted, allowing users to click through and view associated sales data. The underlying dataset can also be downloaded in raw form via the French open data portal.
Coverage is broad across France but remains incomplete or less standardised in certain areas, including Bas-Rhin, Haut-Rhin, Moselle, and Mayotte, due to differences in local land registry systems.
