Agreed. I don't say this lightly, I've just spent £300k on a 1930's semi!
Discovered some interesting things once I'd moved in, but it's all part of the fun.
Agree also with the neighbour comments. Try and pop around to the area on a few free weekends/evenings or something and see how things look. This is what we did and I'm really happy with our purchase. Don't forget, an offer isn't legally binding, so get offering, and if you do discover anything seriously wrong, start talking to them, and if they can't resolve it, then you pull out.
