They don't work so well for most syndicators and sophisticated operators in the space.  

I wish to establish my business there and operate in Georgia.

Good agents will make this process as seamless as possible and will already have all of the contacts in place for you. 

Being active duty military, if you wanted to remove yourself from the day-to-day operations, a vacation rental management company would probably take 25-30% of your revenue.  

A commercial property can be too many things.In general, the value of any commercial property is determined by the NOI - Net Operating Income.

Research the operator's track record and read the offering documents.Like Evan said, a syndication = pooling of capital, regardless of the asset class or the part of the capital stack the investment is applied to. 

Room rentals will operate with higher expenses so please keep that in mind when you're making the decision.

As for "who might be the preferred operators"?

You should schedule a call with all 4 and learn what they specialize in, the markets and how they operate.  

Sure as hell beats paying $40k to an actor fronting for a real estate marketing company operating out of Las Vegas or Salt Lake City and providing guidance by a failed salesman reading answers from a script.
