After advice on a property that has been in process with the solicitor for months . We are really close to completion when some of the enquires are left only to answer. Just on Friday these enquires were answered and one Major sticking point that has come out is the Dormer which has been there for 6 years does not have a building reg certificate . House was advertised as a 2 Bedroom, and sellers are saying to take indemnity policy . My solicitor has left it up to me whether to proceed ahead , if i do the mortgage lender would have to revalue it also. Also I'm paying 48% deposit . Any advice as what to do never purchased a house before
