Just interested as she is a bit, er, volatile and keeps threatening to pull out unless she gets everything her way. We are first time buyers so obviously have to put down our 10% deposit at exchange. Presumably a lot of people who are selling don't generally have the cash to put down as a deposit on the house they are buying - so is it just us who is exposed after exchange? Or would she also lose a lot? We all want about a month between exchange and completion for various reasons.
