However, after reading this it sounds like I will be upsold mentoring for $16k to go along with the price of the 3 day workshop.

In general they will add the ADU only if it is existing living space such as workshop, bunk house, office, etc.  

Imagine if the investors approached it as a work-shop to co-op networks, ideas, resources to change direction of things.... 

Any specific workshops, courses/masterminds, or maybe finding someone that's willing to let me shadow them? 

Attend real estate workshops, engage with local investor groups, and absorb insights from experienced investors.

And I understand that i am college kid with no money or experience but then you see people like Rob Beardsley who dropped out at 20 and bought a 200 unit property through syndication and then you think, hm, maybe its possible.I am fairly new to the real estate investment and what I have learned so far is choosing a mentor and attend real estate workshops then expand your network which will help you to pick up the pace, select your investment strategy and grasp the business model.

It explains why very few flippers are adding single ADUs and if they are they are usually a conversion of exhisting habitual space (bunk houses, detached offices, workshops, craft rooms, etc.  

What is MFM and was this workshop held here?
