One county we know allows 7 manufactured homes per acre or 16 RVs.  

manufactured home on owned land built in 2002.

We found a bigger difference in price comes down to what level you want to put in your homes, each of the manufacturers have several levels of quality, and each of those levels competes with competing brands fairly closely on price.  

There's a lot of manufactured homes, too.

Lets say you own a manufacturing business, and you decide to purchase the property that you use to run your business. 

Forget the stock market, I'd buy investment properties near a Toilet Paper/Paper Towel manufacturing plant, watch it spike in value for the short term & then sell before it dies down :)

I'm not as convinced with manufactured housing in the short term, I think there will be some issues with collections, but will perform very well in the long run simply due to the lack of affordable housing.

Built like a trailer with 2x3 inch exterior walls and 1x2 or 2x2 interior wall const. which makes them very flimsy and difficult even dangerous to repair.Interior paneling is usually a 3/16 inch photo-finished veneer which for the most part isn't even manufactured any longer.Flimsy aluminum siding no longer manufactured and hard to repair.Trying to replace interior wall paneling and/or aluminum siding with heavier materials which is about all that's available with today's material selections can drastically overload exterior walls causing sagging and settling unless reinforced by perimeter piers which still isn't a good idea for lots of engineering reasons.Roof were usual a 1x2 truss system with a rolled aluminum skin place on top.

Ive thought of doing this same thing but with modular/manufactured multi unit buildings.
