I've lived through a couple of these before. 

40k prefab20k electric and water hookup10k land dev100k 1-2 acreOrrrrr170k duplex with prefab home in back of yard ( section off drive into prefab and section off duplex yard)rent duplex - live in prefabthen rezone property for appraisal of two property

Many offer live demos, but it's going to take me forever to research these from scratch. 

One side is rented long term while I live in the other.

I am partial to east Dallas as that is where I live and house hacked for years (before it was called house hacking!)

Tier 1 hospitals near where I live (Raleigh) are Duke / UNC hospitals (Durham/C.H.), Wake Med (Raleigh) and ECU/Vidant (Greenville).

I do free live trainings on thursday.

I actually got my real estate license partially for something to do and I enjoy the work (maybe because I have other sources of income from my rentals and dividend stocks that more than cover my living expenses, so I’m not desperate for every commission like some agents are.

Tenant 2 on the other side has supposedly been living in her unit for 20 years, and she currently has a roommate.

I would screen her first so you know who will be living there but assuming she's ok, would just add her as an occupant as opposed to a responsible party to the lease.
