Besides the whole idea is not to sell properties with problems, can you imagine how long it would take before someone came onto the forum and told the world of their problem. You'd be likely to loose your business over £3-5000 and that wouldn't make much sense at all!
I'm just nitpicking now, but I think it all depends a bit on what you call problems, and how soon problems manifest themselves. Every house has some kind of problems. Mis-descriptions seem to be fairly common with BG estate agents anyway, sometimes possibly through language problems. My favourite example of an outright, easily believable lie is this house in our village:
https://www.motoroads.com/PID_14959_Hou ... Varna.aspx
It is a very old house which was renovated thoroughly and beautifully a few years ago, I saw it being done, yet is is advertised as a "newly built house".
(But isn't it just gorgeous, I wish someone would finally start living in it! No, I have no connection with this house, don't even know who owns it!)
But we are meant to be discussing ebay, apologies for any sidetracking.
