So cross, we were on the verge of exchanging, we are at the bottom and renting as we already sold our property. Total number of chain is 4. The people at the top of the chain were happy to vacate as they hadn't found anything to buy. Today, we find out they have found a house and refuse to move until they complete on the house they are buying. I am yet to find out how many more this adds to the chain. Very annoying!!! I am paranoid our vendor will pull out as they need to exchange in order to secure a school place for their 2 children to start in September as they are relocating to a completely different area. Am I being unfair in thinking the people at the top of the chain should let us all exchange and sort something out?! Do they not realise that if the chain collapses they won't be able to buy their house anyway!!!
