We are in the process of remortgaging and were going to increase our mortgage to extend and create a big, open plan kitchen. We had our house valued before we started the process. Local estate agent valued house within a band. We are now part way through mortgage application and two valuations have come in much lower than the local estate agent valued it at. (The higher of the two is 10% less than his worst case scenario/fire sale valuation).
I'm now worried about spending extra money on the house and never recovering what we spend. The local agent reckoned we would add significant value but I'm now nervous about his view. Equally, it is a difficult property to value and we aren't doing it up to sell, its very much the house I'd see us staying in until our children have left home and we think about downsizing for age reasons, so the extension is to make it our perfect home, not for anyone else's benefit.
What do people think? I don't want to make a bad financial decision and this whole process has made me worry that there is something wrong with our house. But in the area there is a massive shortage of family housing, so moving isn't really an option even if we wanted to.
