Checks run before any listing is published on Briveo, and they depend on the channel. A property marketed BY BRIVEO under a mandate requires a signed, unexpired mandate (French Hoguet law), the energy performance certificate with its report and still valid, and complete fee and co-ownership disclosures. A listing published by a private seller, which Briveo hosts without acting as intermediary, requires the energy and greenhouse-gas ratings (French Building Code art. L.126-33) and the co-ownership disclosures, but no mandate. Briveo is not the intermediary for that sale. Every card states which of the two it is.

Yes. Set up an alert with your criteria (budget, surface, number of rooms) and you will be notified as soon as a new matching property is published in Chaumont-en-Vexin.
