Asking for advice please. Almost 15 weeks in since our property got an offer. We're third in a chain. However, we were originally told by our buyer that he was selling to a first time buyer, so a chain of 2. This is why we accepted the offer (we had two more and is appeared to be the shortest chain). We found out yesterday this is not the case and there is one more buyer at the start of the chain who is the ftb! We were mislead here! We understood that all searches and enquiries are back and ok. We have now missed our third exchange date due to "one more question to be answered" by the ftb's solicitor. To add to the stress, the seller of the house we're buying is getting anxious as everything is in place for exchange. Our solicitor has been great so far and she's been pushing for dates for nearly two weeks. We spoke to our buyer yesterday and insisted that an exchange date takes place next week, if not, we will lose our new home. Any words of wisdom on what to do next. Thank you.
