The reality is that you will not find that in the seller finance space, and even if you do, there will be virtually no discount. 

I am interested in the Brrrr method and I want to evolve from wholesale space to that.

It has ample basement living space, that the tenant uses as a third bedroom.

My plan for this year is improve my credit, get my real estate license (to increase my income on top of my W-2), possibly career transition into the property management space (to learn more), and save as much as possible and learn as much as I can.I’d love to house hack close to home but my area is so expensive it seems like it’d be close to impossible. 

There are cases of local governments delaying payment due to budget constraints.

If the commercial space isn't too disruptive, you shouldn't have an issue renting an ADU up there.

P.s I am a residential MLO so I have a scratch of knowledge in the real estate space.

MHP is a mature space with many proven operators.

They are a commodity, and owners are competing directly against hotels in this space, so rents are ultra low.

im in Orange County CA and there is a huge market here for room by room rentals here. i've been doing this for quite some time (over a decade now), and it certainly has its pro's and cons. my advice if you go about this is make sure you do proper vetting before moving someone in... not only for financials/ credit-worthiness, but also for temperament and expectations in a co-living space. we ask a lot of questions like "how do you handle conflict?"
