24yr old nurse, single, have scraped together enough for a deposit on a flat. Just been let down on my purchase days before exchange as vendor decided she could sell for more money (now asking £17,000 more than she had accepted from me) She told me she wasn't going to sell at all & then put it for sale with a different agent the next day! I've now put an offer in that has been accepted on an ex-council flat at 142 Mayday road, hoping this is a sensible purchase but feeling nervous about it. Flat is 1 bed, large, top floor (7th) with views to Crystal Palace, tatty, needs new kitchen & bathroom, carpets, decorating etc. Does anyone have any advice?
