DD and I are living in what you could call a tin-can cabin -- it's a '71 double-wide, 800 sq. ft., plus a 10'x15' addition. We are blessed in that prior owners had gutted it out -- six inches of insulation in the walls, plus they added some in the ceiling and the floor
They put up all plywood inside instead of sheetrock, and put down a floor made of 2x12's. The floor looks really nice but does have cracks between the boards -- they should have let them dry indoors for a while before fastening them down. On the outside it looks like an old double-wide, but inside it's pretty nice, doesn't look like a mobile home at all. I don't think I can post pictures as I'm on my phone.
There were two advantages to getting this place. One, we got a nice snug little house on an acre and a half (46 miles from town) for $35,000. Two, the property taxes on the house, land, and improvements is about $185 per year. In Oregon. :-)
