The reason you can generally only participate if you are accredited is because regulators know that it is easy to get taken in these deals and it is assumed (wrongly so IMO) that if you have a higher net worth and can plunk down a big chunk of cash that you have the sophistication to understand the investment. 

Heard there may be a casino coming at some point.  

Sellers are sophisticated enough to pick the best offer, they only see the price and the terms, any other negotiating tactics are a waste of time.  

Regional hospital in Denison, Two huge casinos in Oklahoma and a number of smaller ones, Four TI chip plants under construction, and they already have a plant there now, but not sure what it makes, Tyson foods factory (I think chicken), airport that I would think gets some cargo service (but no passenger service yet). 

A lot of the bare ground has been getting used for google, Amazon, weekend stay hotels, bass pro, casinos.  

Or that they’ll be able to use a highly sophisticated technique that can really only successfully be utilized when all the stars align and in circumstances that occur irregularly and need to be recognized as such, always by an experienced real estate investor.  

At that time I am not sophisticated enough.

You listed two but in broader terms financing (assumable, owner financed, sub to, fha, new 95% OO LTV that in most ways is superior to FHA, dscr, F/f conventional, NACA, VA, etc), value adds (development including ADU, upzoning, traditional rehab, sophisticated value adds that leverage localized rules, coop/tic, etc),  property types (residential, commercial residential, land, storage, MHP, industrial, office, camping, hotel/motel, etc), passive/active investment methods (GP, LP, REIT, nnn, self managed, pm, flipping, mineral right, lumber rights, etc), residential rent models (LTR, STR, MTR, rent by room, student housing, arbitrage, etc).  

I think that piece would speak to the more sophisticate audience.

But sophisticated investors have a certain asset allocation mix with REI say 10-80% of their portfolio.
