I agree with Bemis, to a degree. It's a fairly simple investment model because the management is easy (if you have the right manager) compared to retail, industrial, office, etc. Single tenant, NNN deals are a solid investment, but returns will be much lower (and safer) than self storage.

I have owned and managed SS (and debt secured by self storage) and we are looking to build a few new properties in the next three years. Happy to help if you need a few minutes on the phone.

Good luck.
