The buyer of our apartment has signed contracts to buy our apt and given her deposit. However as it is a NE mortgage we can't co sign the contracts until the contracts for new house are ready and there is a few weeks delay with these. She now has requested for us to fix a door and a tap also but this was never mentioned before she signed contracts. Our solicitor is away on holiday and I would love some opinions how safe we are at the min. We feel very vulnerable.
