@George S. - I own a Triple Net Industrial and I will say a few things that I don't believe have been covered yet:
(1) Anything NNN in Industrial or Retail you have to be a sector expert for the prospective tenants. You have to KNOW their business. SWOT. I just came back from an investor summit where every syndicator who does retail NNN (including small markets you're looking at) made an extremely compelling case for the strength in retail vs. what the news is covering. They're having a hay day because everyone thinks the market is collapsing and it's creating massive buying opportunities. They know their tenant as well as anyone. I think there's incredible opportunity for triple net from a cash flow (and overall return) perspective however I think it takes a very experienced sponsor or investor to do them well and with extremely conservative underwriting standards.
(2) ST cash flows are more supportive than some traditional MF and due to the LT nature of the leases, you don't always have the turn and burn you get in MF. What I mean is MF investors typically like to get in and get out. That creates capital events, paperwork, hopefully profits but then taxes if you don't complete an exchange.
(3) I second the cap rate comments (way too low) and I'd second shopping other syndicators or fund managers and get a better handle of the industry at large.
Best of luck to you.
