Before the 2008 meltdown my parents sold their house and the first offer they accepted it turns out the agent was also the person that pre approved them for a loan. Of course that fell through. Not sure that's even semi legal anymore. They didn't know till they couldn't get financing and they looked at the letter stating they were pre approved, not the same comany but same name as the agent.
Luckily it was post Katrina and my parents area got no damage at all. A lady down the road bought the house for her sister that hers was destroyed. The lady owned a sex toy company and she paid for the entire amount with a company check and it the corner it had a dildo on it. Parents drove down to the bank which was the same as the sex toy company and it cashed. Simple solution.
