When buying a second-hand house in Shanghai, only the husband's name is written on the property certificate. Do you need the original ID card and the original household registration book of both husband and wife? During the transaction, the spare parts required by customers include: identity documents; Household registration book or household registration certificate; Marriage certificate: married people need to provide marriage certificate, divorce certificate and divorce agreement or divorce judgment; Birth certificate and household registration book of minor children (if any). Note: All the above spare parts must be provided to all members of the customer's family. As for the platform, I personally recommend 985home, which is a brand consulting organization focusing on real estate services. Driven by big data in science and technology, it provides full-process solutions with personal tailor service as the core for buyers. Consultants will provide face-to-face consulting services to customers, analyze customers' needs, give suggestions on buying a house, then give screening principles, and then put forward plans. Is my answer feasible? If possible, adopt it.
