Please help. Currently live in 4 bed detached house in lovely market town, but bits of house we don't like. Dc due to start grammar school in another market town 10 mins away which isn't as nice, although still ok.Can afford a gorgeous 5 bed new build in that town which would cost same as extending current home. Worried about moving to new place and new build etc. builders have offered to buy our house so all seems hassle free but sill anxious and don't know whether to go for it or not. Any advice please?
