DP and I are in the process of selling our flat to a couple. We knocked quite a bit off asking price as bathroom needs doing and couple were in a no chain situation. The management agency for the flat have been awful and really held things up and we've had the buyer on the phone constantly chasing us. Got all that sorted out and wanted to complete today but it turns out that despite what they told us, and despite all the chasing of us, they are not in a position to move. They actually have an associated sale that is not going to be completed in time for them to complete today. We found this out earlier in the week and were furious, but decided we would continue providing we exchanged today. Turns out they are now not in a position to exchange either as their deposit is tied up with the sale, which can't exchange as their buyers mortgage offer has expired. DP doesn't know about this yet but I am so cross.
