Your retirement and health costs alone will eat you alive.

I also agree that it is the wrong response to ask them to put TP in the trash, that would be a health hazard.

DEFAULTS Tenant will be in default if: (A) the Tenant don’t timely pay rent or other fees and charges they owe; (B) Tenant or any guest or occupant violates this Lease, property rules, or fire, safety, health, or criminal laws, regardless of whether or where arrest or conviction occurs; (C) Tenant abandon the property; ....When Tenant is in default, the Landlord has the option to declare the entire balance (all outstanding balances including but not limited to invoices, rent, cost due to damages/abandoning the property) payable hereunder to be immediately due and payable; the Landlord may exercise any and all rights and remedies available to Landlord at law or in equity and may immediately terminate this Agreement.XVI.

And I have already mentally done the gymnastics to be alright with $500/mo. in cashflow.

I wish you great health and happiness. 

I think there is a chance that you don't actually hate your rentals, but rather, you hate where your mental health/stress level/amount of free time is.

What do you think stagnant $/sf values alongside rising rental rates & absorption mean for the health of the market?

The aids health foundation is sponsoring, to the tune of in excess of $10m, a proposition (prop 33) to over turn Costa Hawkins.  

The tenant is mentally unstable, didn't pay rent over a year, got evicted, forced out by the Sheriff and kept coming back to the property by breaking locks and lock picking.

So, they don’t have health insurance, savings, retirement, etc.
