One other major consideration is the possible UBTI that could come into play due to the multiple income streams (retail chocolate shop, farming on the parcels, wholesaling beans with other farmers, etc.).

I don't want to work that hard, since this is just another income stream for me, so I proceed accordingly. 

Robert you are missing out on a easy and lucrative income stream that there is no reason to avoid.

As as a note investor you are buying paper to receive a cash flow stream. 

@Derek DeCesere, I am in Southern Maine and have worked with a few clients that have rentals along the coast and do AirBNB all summer and then short-term rentals in the offseason to lock in a revenue stream.

This for sure is not a passive income stream - managing our own Airbnbs has been very active, but I love doing it.

That may change at anytime, of course, depending on the ebb and flow of the economy and the impact of that on their payment streams. 

It is another income stream for the property if you are willing to rent it to tenants.

Also I get a stream of leads.

My goals is to build a stream of passive income by purchasing income producing properties in the Florida Keys as well as outside markets.
