Know What Your Property Is Really Worth

Our model compares your property against more than 8,500 real transactions recorded in the official French DVF (Demandes de Valeurs Foncières) database, narrowed to your sector — not just your town. Sector-level data accounts for street-by-street price variation that town averages miss. The model returns three estimates (conservative, expected, premium) reflecting how the property could be positioned at sale.

Average accuracy is 94% on completed sales we have back-tested. Accuracy is highest for villas and apartments in our eight core towns (Valbonne, Mougins, Biot, Grasse, Opio, Châteauneuf-de-Grasse, Le Rouret, Roquefort-les-Pins) where comparable transactions are dense. Bespoke or trophy properties — historic mas, sea-view estates above €5M — sit outside the model and require human valuation, which we provide on request.

Transaction prices come from DVF, the open-data dataset published by the French Ministry of Finance covering every notarised sale in mainland France. We update our local index monthly. Property characteristics (size, condition, features) come from your wizard input and are weighted using comparable-sale regression at sector level.

Yes — the valuation is free and confidential. We do not share your inputs with third parties and we do not list your property publicly without your written instruction. We will only follow up if you tick the box requesting a conversation. Data handling follows the GDPR and our Privacy Notice.

Nothing automatic. Some owners use the figure for tax planning, divorce settlements, or simply curiosity. If you decide to sell, our advisor can refine the estimate with an in-person visit (typically within ±3% of the model output) and walk you through the marketing strategy. There is no listing commitment until you sign a mandat.
