Hi everyone, thanks for the advice. You're all right.. Barclays probably would expedite the funds if our buyer and his solicitor were inclined to ask them, which they've said they won't.
Mainly because, on the incredibly small chance that we fail to complete, then our buyer would have his mortgage offer refused and he doesn't want to take that risk. Even though the knock on effect is that now we won't complete until next Wednesday when I'm going to be 2 days overdue. Buyer said he didn't like being 'rushed'. I can't even.
Luckily our vendor was really nice about it when I rang him and basically said the only inconvenience for them is an extra week of storage and an extra week living with his mum. But it's just so annoying that we've campaigned for this completion date for literally months, to avoid the whole scenario that we potentially might have to complete and move with either me overdue, in labour, or in hospital with a newborn, and now we're facing that exact problem.
AND BREATHE. I know I need to stay calm but, facking hell, it's not easy.
