Because people are suffering daily from the stress of buying or selling a house. It costs both sides a lot of money and no one is secure of their purchase until the day they move in. Please Please Please change this.
Please, please, please can we change the law so that when purchasing a property the contract can be signed at the beginning to prevent gazumping. This is done in New Zealand, Australia and North America very successfully. My son is purchasing a house and just as he is about to exchange contracts the vendor has accepted another offer, so all that money spent on solicitors and surveys and arranging a mortgage etc is now wasted and must be repeated again for the next purchase. This has to stop to prevent the misery it causes and the costs involved. Please change this now.
