Long story short (ish). Our mortgage valuation agreed with asking price but surveyor has real concerns. We've spoken on the phone but he's offered not to charge for the survey if we decide not to go ahead and receive the report. He has given me a list of the 20 odd things that mainly concern him (drains, electrics, plumbing, roof, woodworm, stairs, damp). I've used him before so I trust his opinion but it seems more his gut instinct about the dodgy diy than anything really specific that is making him concerned. He reckons property is worth another 10% less than we offered (another 40k less). What would you do wise mumsnetters? Options are pull out ie without getting survey so as not to incur any more expense or get survey and try and negotiate money off?
