Sorry for your loss OddBoots 
Luckily our surveys have been done but we have a couple of small internal repairs to do before the buyer signs their contract; we are lucky to be in contact with them, I suppose, and their buyer (bottom of chain) is not in any rush to move which gives us a bit of leeway - it's the lack of clarity or timelime that is nervewracking and the thought of being stuck in limbo for two months until the next stage is announced.
Hopefully more comprehensive guidelines will be released tomorrow, though not feeling especially optimistic.
Finger's crossed for everyone.
