Le Goupil

Goupil shows what homes really sell for in France, neighbourhood by neighbourhood, using public data only. KNOW THE REAL PRICES Every recorded property sale (DVF, published by the French tax administration), mapped by neighbourhood across 100 metropolitan areas, and by town everywhere else in mainland France. See the median price per square metre, its range and how it has moved over five years. CHECK A LISTING BEFORE YOU MAKE AN OFFER Enter an address, a surface and an asking price: Goupil compares it with about a hundred comparable sales nearby and tells you where it sits in the local market. It is a reading of recorded sales, not a valuation. EXPLORE AND COMPARE A price map colored by neighbourhood, full pages for each neighbourhood and town (rents, rental yield, schools, transport, risks, energy ratings of the buildings), side-by-side comparisons, and a screener to find the areas that fit your budget. FOR BUYERS, SELLERS AND LANDLORDS Whether you are buying a home, selling one or renting one out, the figures follow your situation and stay on your device. OPEN DATA, NO ACCOUNT Sources: DVF (tax administration), INSEE, ADEME energy ratings, IGN maps and OpenStreetMap. No account, no login, no advertising. Available in French, English, German, Spanish and Italian. Note: property sales are not published as open data in Alsace-Moselle and the overseas territories, so prices are not available there.
