We may give them a call and go over to look at it and decide if it looks like it would be worth fixing and then have a inspector take a look. If it is going to be to costly then we will just wait and either find another place or build a house. Most of the other houses around are manufactured homes that are $75K and up. 
I did have a question about house foundations I didn't know if anyone knew the answer to or not. My SIL built a 2 story house with a garage for the bottom half. She had to have a footer built for her slab. Do all 2 story houses with a slab foundation need a footer or did she just need one due to it being a garage with no center support beams? If we built a house it would most likely be a 1 1/2 story but wasn't sure if we would need a footer for the slab. We wanted to have stained concrete floors with possibly radiant heat and a/c in them.
