It turns out that the info provided to us by our seller is wrong and there is no completion certificate or building regulations approval for some renovations that they have had done. In addition our surveyor said they looked like they might be of a low standards which of course we have no way of knowing unless we dismantle part of it to check for insulation, damp proofing etc.
We plan to sell in a few years and don't want to inherit this problem. However, we are only a few days off exchange and completion (this has only literally come to light when they couldn't provide the paperwork they claimed to have).
Does it seem reasonable to reduce our offer to take this into account and any future works? We have been given a figure by our surveyor on a likely cost, but of course there is always the chance it's fine, but we just have no paperwork so can'tfind out either way.
We wouldn't have offered on it had we known, but now we just want to move and it makes sense to seeing we can save the money and sort it out ourselves. I'm very annoyed as they said it had all been approved and signed off, but it hasnt.
