Hey, I had that type of problem on the DAY of closing... we were trying to sell our home in Ohio, but we lived in PA now.
The guy put down the deposit, we signed our papers, Fed Ex'd them over, got his signature, and was waiting for his final papers to be signed by a fax machine..
Then we get a phone call from his realtor. He went to get his money for closing, and his ex wife (soon to be ex wife) liquidated all the money, and he was left high and dry.
This was the DAY of closing, TIME of closing... you at least had a whole day notice.
We got to keep his deposit, but it was still a pain.
