Make sure that you file all necessary paperwork on time and check with the bank if refinancing frequently. My daughter bought a house that she took possession of yesterday where the former owner was in negotiations to get bank refinancing and was told everything was fine. Two days before the auction they were ready to close and he was suddenly told that he had to come up with an extra $3000. He didn't have the extra cash so she got the house. I have bought 2 foreclosures where the former owners said they had paid a company to keep them out of foreclosure but the auction happened anyway. I took possession of one of those houses today.
Good luck to both of you and anyone else having trouble these days.
