The thing is, unless you're loaded, once you've coughed up nigh on a £1k say for a full survey, you're then unlikely to read it, see all the problems and then say, "Ah sod it, this house is no good I'll look for another one" and pay the £1k survey fee again on the next one and so on. You're more likely to try and negotiate the price down based on the faults, fail, pay the full price, move in and have to sort the problems out. Exactly the same as if you didnt have the survey done in the first place except your £1k out of pocket this way round.
