I'm buying a house (builders finish) which was due to be completed in August. Got mortgage approval at that stage and it stated that the mortgage had to be drawndown by 1st December (NIB). Of course the builders aren't on the ball and it's still two weeks away from snagging. Does anyone know if it's much hassle to extend the drawdown deadline as I don't want to drawdown the mortgage and have to pay the mortgage and rent together for longer than I need to.
