We still haven't exchanged either 
Just found out that the investment buyer at the very beginning of our overwhelmingly long chain offer expires on 20 August. All pushing to complete by then but searches and enquiries still outstanding on one of the properties further along the chain. The same link also need 10 days to get funding released to complete as cash buyers.... so we need to exchange by 10 August at latest
Investment buyer at beginning needs 5 days to get deposit cleared and won't do this until the searches etc are all sorted further up the chain
It is all far too skin of our teeth for my liking
