I'm not sure it would be worth doing that just to save a fraction of a percent.

To me a 'good tenant' doesn't fall behind on their rent, they may just be late a month here or there, not pay a small fraction of the rent.When I come across a situation when someone can't pay their entire rent balance, I start the eviction process and enter into a court ordered stipulation.

I don’t think anyone in their right mind would say you paid $47k more than the assessed value (which means nothing in many states as it’s only meant to be a small fraction of true value in places like Las Vegas) and the land went up $80k (from $50k to $130k) while the building went down in value $30k (from $200k to $170k). 

Also some people desire battery backup for reasons like critical power loads that can not be without power for even a fraction of a second such as life support systems/ important electrical equipment, or "preppers"/survivalists that desire full energy autonomy for peace of mind, or locations prone to power outages where people work from home and require reliable power, etc.

Is that the full security deposit or only a fraction of that?

It immediately occurred to me that those listed are probably a small fraction of actual number of REI’s in the area (Martinsburg WV is in proximity to MD/DC/VA).

Selling them all at once will likely drop the price of all of them if they are in the same area, but I've seen C/D class properties sit on the market for years and get bought/sold for a fraction of listing price when the seller gets fed up with waiting. 

That represents a small fraction of the additional return one would expect based on 60% leverage in a deal.

@John Hagen, Tenants in Common is both simply a way to own real estate (as tenants in common, single tenant, joint tenants, etc) and a name for a specific passive fractional ownership of real estate that has been set up according to Rev Proc 2002-22.The products listed by @Jacqueline Gardiner are the latter. 

This way all the fractional owners will get 1st lien position on the property; as one mortgage.
