I have the opportunity to list sell multiple acres of virgin waterfront property in Trinidad and Tobago.So I'm looking for potential investors as well.Which islands do your company typically operate?

I think the problem here is your lumping ALL syndicators, regardless of operational time and quality, into 1 big generalization. 

Has anyone tried to operate a business on a plot of land with minimal development until it builds revenue for a structure (flea-market, private park, outdoor event venue, etc)?

I was thinking of doing Airbnb arbitrage in Cincinnati but discovered that there is a restriction that the STR operator has to live within 50 miles of the property.

The main reason is other buyers who are better able to pin down operating costs will either outbid you because they have their costs right, or you'll outbid them because you have your costs wrong. 

Aim to increase your Operating Income by acquiring 3-4 units for the next purchase.

I successfully operate a small portfolio (3 duplexes and three single families) out of state and a good  property manager is essential. 

There are also additional costs of operating and maintaining an LLC, like separate bank accounts, annual report filings, tax filings, etc.2.

That ends up leaving a void that's filled by unprofessional, and in some cases outright criminal operations there in the PM space.
