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.
