We found a gorgeous house and made an offer over the asking price as it came down to best and final offers. It was accepted and mortgage applied for. The mortgage valuation came in at zero, because the area is 'majority student which will affect resale value' - despite the fact the house had several offers over the asking price. We've done our research and surveyor comments are wrong, area is under 50% student and in desirable postcode, so we're appealing it with v. supportive EA and broker.
Has this happened to anyone before? How long does an appeal like this usually take?
