Or sell it out right or sell on contract or LO.. thats the options from my POV

In '22 I sold 19 on contract / with seller financing.

before even finding a buyer, I’m pretty sure first you have to find a good title group or real estate attorney that will do your paper work and contracts, and provide you with insurance if something happens later on. 

If you are going under contract you should have the ability to close, even if you don't possess the intent.

I found the county criteria which reads as:"Property must be minimum of 1 acre, meet the underlying zone district, have adequate parking, meet the requirements set for by the Wildfire Hazard Overlay District, have valid water and sanitation, have legal access, use the primary dwelling unit, be free of violations, and have no substantial detriment to the intent of the Zoning Resolution."

- Is it possible and worthwhile to legally make the Duplex a Triplex?

Legal action- no attorney is willing to take this on?

His real estate contracts and some of the advice makes sense. 

The number 1 thing would be to have a lawyer look over the terms and contract to protect you in case something changes for them through the course of the owner financing.

I realize that once someone creates a letter of intent they can start on the due diligence phase to learn the financials, physical, and legal but what else can I learn about a property before making an offer?
