@Alvin Sylvain in the eyes of the law and regarding housing, an ESA is treated just like a service animal.

Follow the law and send the exact required notices. 

Then set a policy as to how much late rent is enough to ignore vs filing a unlawful detainer (or whatever your state calls it.)

From what you stated, you have enough to substantiate his eviction, but you must be able to prove those incidents.  

I'd estimate that there are less than 1,000 legitimate, or "professional" wholesalers, in the United States of America, as defined by individuals who make $100K flipping contracts, and collecting assignment fees, in any form, and who have made that amount of income more than 3 years in a row.

Cities and states have enforced this policy for well over 50 years and it always stood up in court.

Many people don't want to self manage from out of state, and professional managers can suck up alot of the cash flow, and not do as great of a job as you would've hoped. 

The PM should be an expert on state law, and they should have policies and procedures in place to handle these situations.

We’re property managers based in Redding, CA, and the laws here favor the tenants, making situations like this even trickier.

The state laws (do not quote me) appear to not let these companies increase rates (or its not easy) to pick up the losses.
