The best way to build relationships with cash buyers is to establish yourself as an authority in this space.

California charges a minimum tax of $800 a year per LLC, and more if you have gross receipts in excess of $250k.

I have not charged them late fees, but in totality, it could excess $1k.

Every year, the local Housing Authority in my neighborhood issues a market rate report for apartments, listing fair market rents for studio, 1br, 2,3 br etc. 

Further, a state that an entity does business in but is not organized in or registered in can declare authority over that entity due to the entity being a “foreign” entity doing business in that state.  

Usually as long as their are no life threatening issues (no HVAC, windows won't open, no hot water), the housing authority will began to pay the rent and give you time to address the required repairs.

If they can’t provide evidence of this, or a Visa (student, etc) that authorizes the duration of their stay, then they’re here illegally.

A ton of questionable money raisers are running around as "co-GP", but do they "really" co-GP or is it a shell title with no authority nor a legit role outside of raising $ for a cut?

I made millions of dollars in the great recession b/c people used excessive leverage and lost properties to their lenders.

Next, 10k in damage seems excessive for an emergency leak, since if the leak was in a wall, it would most likely result in most of the water falling into a basement (if there is a basement) or it would pool along the floor.
