If they aren't interested in a better unit, then I would respectfully ask them to start looking for another place to live.  

.- When house hacking, be sure to establish a good relationship with your tenants, but avoid "being friends".

It helps you establish one economic unit to meet material participation hours.If you are in higher income tax brackets, I suggest getting a multi-member LLC for audit protection.

With due respect, since loan docs are state-specific, be careful asking here which documents you should use.

Have the tenant sign off on a move-in checklist to avoid disputes later.If your not using a property management company, you will also want to establish a plan for handling maintenance requests and emergencies.

An Architect can look out for your best interest in the project plus can bring all the Engineers necessary for the build (Civil, Structural, MEP, Sprinkler/Fire suppression, etc.)As far as the build itself, if it's in an established city or town on a tax lot, then you'll need to go through the design and permitting process, gain zoning approval if necessary, and then build up from there.

Wow, @Ryan Dickerson I love your post because you seem to be on the right path.Figuring out your construction cost and building your team prior to entering into deals can alleviate a lot of stress during the project.Also, your respect and understanding of the value of a general contractor's time is impressive. 

Call the cops the minute someone breaks in, then they won't have time to establish themselves.

Lastly, I switched to a LTR & because Kiavi said that they only refi on LTRs but I needed to establish that and just like that poof, a whole year gone. 

If you plan to respect these rules, cartels shouldn't be a concern.
