This is what I got from my solicitor yesterday, part of the email from the bungalow owner's solicitor
Extract of email which I have received from the sellers’ conveyancers:-
It is very much down to the lenders solicitors giving final sign off – it is taking a ridiculously long time for them to do so, I cannot disagree with that, but I’m afraid we all have to wait for them to get the job done.
My client is calling me every few days, so please reassure your client that the delay is not down to any reluctance to proceed on my clients part.
So I carry on twiddling my thumbs and waiting.
