Agreed a sale offer on my (empty) house within the first hour of being on the market, to a nice young couple who'd sold their house. A completion date was given of 30th November 2021 (the sale was in late August). On the 29th, our solicitors informed us everything 'was cancelled'. No reason was supplied by the buyer's solicitors. Apparently they are not legally obliged to go into details, which I find extraordinary. We contacted the buyer directly who told us he'd resold his property and completion was expected in early January. So here we are in April with no forthcoming news from anyone. All our solicitors can find out is that 'there's a delay'. We're seriously considering giving an ultimatum that unless we're told what the delay is and why we can't even be given an estimated completion date, then we're pulling the plug by the end of April, even though we'll incur costs, not to mention major upheaval to our buyer. What are your thoughts?
