I have a similar problem to classy. My agent gave me a closing cost at the middle of may. I agreed to pay 1500 towards closing cost. A week later he came back and said closing cost were 2300 because of fees. I agreed to the 2300. On May 27 he called and said the attorney got a closing cost from the mortgage companies and that the total had increased to 3500 because the actual payoff had been received and the payoffs were higher that anticipated. After a heated debate, I agreed to pay the 3500. The agent assured me that the payoff was good until the close, which was scheduled for June 24. Today the agent calls and said that the payoff was only good for seven days from the date that the payoff was received and that the closing cost were now a little over 5000. I don't have 5000 to close and can't come up with the additional cash for at least another month or so. What can I do?
