Yes, you can use FHA and Conventional program for a primary home if you are buying a "Distressed" property - (Will not pass an inspection) "Subject to">  FHA offers a 203K loan and Fanie Mae offers a Home Style program which has the sole purpose of working with distressed properties. 

We waited 7 months for the bank to make a decision on the short sale, and once the bank came back with an acceptance counter-offer, our buyer bailed, even after multiple times of telling him this was a really good deal!

Anyone have any insight please?
