I found a property i was interested in for purchase and contacted Knight Frank in Richmond-upon-Thames. It was agreed that i woudl pay what the property was worth so i paid £5000 to have the property surveyed - the value came back much lower than the asking price. The agency then stated that the owner would not sell at the 'real' price!! So, i either paid £500, 000 more for the property than it was worth or lose £5000 for teh survey.
Obviously, i walked away £5000 out of pocket but the staf at KnigthFrank were so rude and unhelpful. I feel totally misguided and would never ever use them as an agent again.
