I'm expecting to receive my mortgage offer next week from NatWest (after a six week wait) but there's a chance that the purchase price is going to be renegotiated following some quotes for work that needs to be done. Can anybody tell me what this means for my mortgage? I'm guessing the offer will need to be reissued to reflect the new price. Any ideas how long this might take? We are at the stage where everything is coming together for exchange and I really don't want to risk a long delay.
