Q7Are the listings in Montesson verified?

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.

Q8Can I be alerted about new listings in Montesson?

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 Montesson.
