I looked at REIN and it is still listed as pending. They may have accepted an offer, but not closed yet. But I am confused as well since it is listed for $117,000, even though Trulia has it for $132,300. If someone buys the house through HUD, there are restrictions. If they are buying it as an owner occupant, but intend to resell, that may be fraudulent. if they are buying it with an FHA loan they won't be able to resell it for 6 months.
Lots of questions and given a little more time I'd be happy to contact the listing agent for you. But something doesn't feel right!
