That's excellent news, I know how frustrating it can all be !
Sometimes the auction has advantages for an immediate sale, but it won't get the best price !
However you'd think with less properties selling solicitors would have more time to each sale and get it completed early but mine which was meant to be quick took much longer but eventually concluded. However months later a lose end was still untied and even after moving in another was then sorted out ! A mad system that seems awfully and totally un-necessarily complicated.
Delighted it is done and I feel for you with the 'line' - yes it does and it is a sad relief... but it can help you move on... a sad truth too.
