2 houses, but only 1 is livable. Will they FHA qualify together?

[Jacob Barnhart]

I have been seriously looking at a specific listing on the market for a while. I believe at one point this was one house on one property, and then the owners built another house on the lot and separated it into a separate property. The original house doesn't have functional heating at the moment so it would not FHA qualify and the sellers are not willing to make repairs. Would I be able to get FHA financing (or any low down-payment financing) to cover both properties with one loan?
