Have to say it's something which is becoming more common. I have come across it on a number of occasions recently, mainly, it has to be said, in situations where the buyer might appear to be more of a risk than others. I'm not saying that this is the case here of course. When I say risk, I mean that the buyer might be young, starting out, have no loan approval in place or that kind of thing. There is no security anyway until contracts are signed whether or not sale agreed goes up on the board, but I understand what you are saying in relation to rival bids. If you do have your loan approval in place and are ready to sign immediately, could you tell the estate agent that contracts would have to be issued to you within a very strict time limit because he will not remove the property from the for sale listings and try to tie it down that way?
