And if it doesnt well - some years ago we were looking to buy a bungalow for MIL just down the road from us. We made an offer which was accepted (we were virtually cash buyers) on what appeared to us to be the perfect bungalow and they agreed to take it off the market. So when I saw the estate agent taking another prospective buyer along I was not best pleased, we enquired why were they still showing people around when they had accepted our offer, and were told they were going to continue to try to get a better price until contracts were exchanged. MIL was extremely upset at the time. We found another even closer to the beach just 2 weeks later.
When the original bungalow was sold my sister in law visited the new people, who were unable to live in the place as the day they moved in the water system "collapsed" leaving them with a bill of some 5,000 £ and several weeks work. (This was 13 years ago). The work was on-going as each time the fixed something another problem came to light.
The moral of this tale is keep looking, dont give in and dont be downhearted .......
