You are about to Exchange contracts on the Sale of a house but by chance you get talking to the neighbour who tells you that he has a buyer for his house who is paying £315k more, has done Survey and is a serious buyer. If you spent about £50k on your house you have the same property as next door. You are too busy raising three kids on your own and running your own business. You have had a crap few years and really want to sell the house to enable you to move and make a new start.
What would you do?
