In addition to the "normal" FHA loan, there is an additional piece which is called at Energy Efficient Mortgage. It works in conjuction with the FHA, allowing many additional items to be repaired that otherwise might dig in to your pockets.
Do speak with your lender about this program, I have used it and it has proved to be very very helpful.
This property would not qualify for FHA financing because of an addition that has been done without permits.
There are, however, many other properties that would qualify for FHA. I would be happy to assist you in finding them!
