Although it would cost more, it would look nicer than the metal shed you're considering, and would be more sturdy and functional.

I will admit I never understood why the US didn’t look at Africa that way (jewels and metals etc..)

The metal building erector I used to do some of the work wanted to lease the building immediately once his work was completed.

So 3 of the homes are metal/metal (siding & roof) and the the '91 is shingle vinyl?

You want something with some kind of siding: metal, aluminum, vinyl, or brick.

Don't get me wrong, during this time frame I've sifted through 100+ wholesaler "deals" and EVERYTHING on the MLS during this time frame which is a good bit of work.It's of my opinion that there are too many toxic gurus pitching get-rich-quick real estate that takes advantage of sellers and buyers alike. 

Few Notable expansions to mention are- Metal Works of High Point, BakeMark, Brown Truck Brewery, Future Foam, Glocal Leather, Lowes Cos, and Pennybryn coming in with a $35 Million investment as well.

It will have a 12/12 metal roof and a combination design of Hardy Board cemititous exterior paneling.

They tend to build a veneer front and sheet metal sides and back and be off the beaten path a little bit because they do not want to pay per sq ft corner money.Having said that there are generally more buyers because they are cheaper to purchase. if  a Dollar Store goes dark the second generational tenant pays less for a sub-prime location.

With a self directed plan, you can invest in a whole range of other things as allowed by the tax code, including real estate, mortgages, private company stock, precious metals, etc.In your situation, the idea of being able to potentially shelter more income from taxes (or make higher Roth contributions), and to be able to invest part of your portfolio in what you know would seem to be beneficial.
