Mansfield Building Society (MBS) has joined forces with BuildStore to launch a new mortgage product aimed specifically at self builders. The package works on an advance stage payment basis, so money is released at the beginning of key stages of construction. Available exclusively through BuildStore, the minimum loan amount is £25,000 and the maximum is £500,000. “By providing mortgage finance in advance of each stage of the build process, our approach should encourage more people to consider self building,” says Gev Lynott, chief executive at MBS
