I also see a space where I can select that this is an income-producing property.

Hi Frank,Rent them out at the highest and best use.What else would you do with office space (???)

There’s also an option to buy the land behind it that could be turned into commercial space with apt above it (maybe hold that property and rent??).

The good news is, you live in the space with this roommate, so a judge will be more lenient with you as this person is directly impacting your home/life. 

I would talk to @Dave Foster as 1031 is his space.

NNN expenses for a tenant would include essentially everything on the interior of their space... lightbulbs, janitorial, HVAC contract, plumbing, etc.Feel free to reach out directly if you have any other questions.

I am a new landlord for a commercial space where a new tenant is in the process of setting up their new restaurant.

I'm not sure the exact guidelines for approving this lender, but I imagine it's very basic: current contractors license, liability insurance, business license, ability to submit an itemized bid, statement of work with milestone payments, and a clear understanding of how the draw schedule works.There is an independent organization that has a database for GCs who want to get certified in this space: 203kcontractors.com.

I started with SFR's but now my focus is in the Multifamily space.

The project included adding a master bedroom, walk in closet, bathroom, laundry room, and tech space.
