If a person has to ask, at all, I STRONGLY advise to use a PM service for tenant placement. 

As a neighbor, personally I don't care if someone smoke a little weed every now and then, but if they are smoking non stop 25 times a day, you might lose a good tenant over that. 

When you say "we," are you speaking about your business or your personal tax returns, or does your business flow into your personal returns because you file as a sole proprietor?  

In your experience what are some ways I can understand the intent of the person who said they're interested in buying? 

I was wondering if there are any recommend in-person meetups in the LA area.

I can also find out everything about this person's license in less than 10 minutes.

If a person has RCV or ACV policy makes a huge difference, than question of what coverage level people had and if they had policy add-on's that cover cost over-runs and all that fun stuff, not to mention contents. 

Owner financing and HELOC on personal residence How did you add value to the deal?

And does the person doing the labor get paid or only the materials paid for by the partnership?

Don't spend time looking for something that doesn't exist. also in the US you cannot sue the police.. unless its a direct assault on your person. your wasting your time..
