Speaking personally, I don’t think any of the 'professionals' have acted in any great faith in the whole proceedings. How someone can go from agreeing to sell on a Tuesday (after previously agreeing to sell to someone who dropped out) to the sale being off by Friday?
I'm very ticked off about the whole thing. In order to buy something and spend the kind of money involved, you need to make a decision at a personal level that you really want this thing. It's a level above asking someone out, but the principle is kind of the same.
I'm going to dwell (no pun originally intended) on this some more and add to this post again.
Update:Apparently, their own house purchase fell through.
