When I had my house on the market a couple of years back, I was quite astonished as to the number of would-be purchasers who came to look, talking about the major alterations they would make. It was a suitable house for a family - three bedrooms, plus large loft conversion, enclosed back garden, en-suite to main bedroom, long galley kitchen. Ground floor loo, etc. etc.
One very young couple who made an offer, which I accepted, then pulled out saying that the price meant they would not have anough money to carry out all their wished-for alterations before they actually moved in.
The people who did purchase it eventually, had a long private survey carried out - must have cost them a packet. After they moved, I realised that had obviously been a survey regarding all the changes they wanted immediately. When I went back to visit neighbours two months later, they had still not moved into the house, but builders had been in there throughout that time. Do wonder where these young couples find this sort of money!!!
