Just so disappointed.
The man who viewed our flat 4 times (!!) before putting an offer last week, withdrew from it yesterday. We had accepted his offer even though it was below the asking price. Apparently he’s found something even cheaper! 
Meanwhile, our offer on a semi detached house that we liked had been accepted but now we can’t proceed further and I guess the semi detached will be back on the market.
Aaarghhh... back to square one.
