I was told 12 years ago my home was a modular when I purchased it. It is on a poured wall basement and foundation. Under the home has wooden floor joists, but they are individually constructed wooden joists not solid wood. Down the center of the home lengthwise there is a steel I-beam. I never found any metal joists anywhere. I was told the home was placed there in the early 70's. I recently listed the home for sale, because I have to move. An apparently highly regarded and experienced realtor agent showed my home yesterday. She told the prospective buyer and my selling agent my house is a doublewide. Based on the framing I described above, does it sound like I have a modular or doublewide? If I have a doublewide, I will have to see what legal action I may have against the prior owner for misrepresentation of the home when they sold it to me!
