We've seen too many buyers sign without reading the EPC, without checking the flood risk, without looking at the HOA minutes. Not out of carelessness, but because nobody told them what to look at. These guides fix that. They're written buyer-side, not seller-side, not agency-side.
How to use them
Each guide gets to the point in a few minutes. You'll find the right reflexes, the questions to ask the agent or seller, and the documents to demand before signing. To go further, run a BienCheck analysis on the property you're eyeing: we cross-check your inputs with public data (DVF sales, EPC, Géorisques) and hand you a score, a negotiation margin and a concrete alert list.
