The bad behavior will continue until someone reports him and someone puts a stop to it.

So, if you give them your skin, without putting them in a position to lose any themselves if they don't act responsibly, and then only you suffer the consequences - you haven't allowed them to learn any real life consequences for their behavior. 

They are displaying a complete lack of respect for you and your property.

You don't want to risk that bad behavior starting back up again on your property.

No  one will get rich this way, you have to put in the work and do the time on your own, you are the only one who can control your behavior and work patterns, and the only one who can make your life better with your choices.  

You can't evict someone for being mentally ill, but you can evict for behavior that violates the terms of the lease.

This behavior needs to be known so it does not continue.

And yes, you're thinking, but your contract says that accepting late rent doesn't waive your right to collect it on the 1st - but what happens is, your behavior ends up waiving the due date by accepting it late.I've heard of landlords who love late fees, as it's extra profit. 

I left tens of thousands on the table by offering discounted rent in exchange for good behavior except in many cases they were not that great of a tenant after all...I raised rents on two units recently and that's an extra 4.2K a year for me. 3 trips to Vegas all expenses included.

He has history of fraudulent behavior.
