Copilot Immo
https://copilotimmo.com/Copilot Immo pulls real transaction data from the French government's DVF database (every notarized sale in France since 2018) and calculates a neighborhood-specific price/m², not a city average. You enter an address, it finds recent sales within 500m, applies adjustments (energy rating, condition, floor), and gives you a price range with a confidence score.
When buying property in France, you never know if the asking price is fair. Real estate agents give biased estimates. Online tools like MeilleursAgents give city-wide averages that are useless (prices can vary 40% between neighborhoods in the same city).
