I am also in the Northwest Arkansas area. 

I come across mobile homes in Arkansas...

@Thayne Parkinson and @Justin TahilramaniI will have to agree...it can be done.I bought some sight unseen in Alaska, yes you heard it, Arkansas and Ohio while living in Virginia sight unseen.

I second the suggestion for Little Rock, Arkansas! 

Construction loan and no money down...money ar closingbto fix property.

Over the years, I've accumulated a house each in Little Rock, AR, and Charleston, SC.

Very close to the mall and the university of Arkansas Little Rock 

My other Idea was to use cellulose to put a r-30 (or more) layer on top of the old rubber.

Footings in Arkansas are typically only 18‐24” deep so moisture cycles (extremely wet to dry and repeat) can cause this movement if both extremes occur close together.No repairs or modifications are suggested or necessary."

For example, certain counties in AR only use 20% of market/list price for the tax assessment basis and will use x% of the 20% to arrive at the property tax...
