I was searching around online for affordable real estate and came across a 1300 sq. ft. ranch style house. I gave a friend some information since she was looking for a place and she went and looked at it. She said it was a nice house but the floor was rippled and the roof needed some support beams. She asked some people about the floor and roof and they assumed it was flooding from the house sitting low. They said it would probably be $10-15K to fix. Can the house be fixed to avoid future flooding problems? Also I'm not sure what type of foundation it has but if it is a crawl space can that be turned into a slab?
