Until this happened everybody else in the chain was ready to exchange it was just the first buyer holding things up given that they probably put their offer in back in october november they had have plenty of time to sort out this negotiation with a neighbour for remedial work they wanted to complete for their disabled son. Did your chain complete with those few weeks
