We are considering buying a new house but it is not built yet. Have had our own house valued and happy enough with it. But if we buy the new house, will have to do deposits, stage payments etc. But whan is the time to put your own on the market so that it is sold in time for the new one to be ready? Also, do lenders let you draw down part of the new mortgage on the new house without paying off the old one (if you have sale agreed but not actually closed the sale) or would we have to look at bridging finance?
