The owner I worked for had a resident manager who actually died from injuries sustained while getting in-between two angry tenants.  

Rents in the Bay Area are absurdly high right now, which I don't think I'd sustainable either.Why not take your money and run--tax free I might add?

On the other hand, getting rich by cheating others is not sustainable either.

@Kai Hodge, I'm sorry your property sustained that kind of damage.

Furthermore, at least in Oregon, a savvy tenant would have a legal claim for a full security deposit refund if the only damage was from pets, and you charged a separate "pet deposit" or "pet fee" that didn't cover the entire cost of actual damages sustained.  

For that amount you could sustain a vacancy for 2.5 months and make the same income for the year.

If you do continue to stay, you agree to indemnify and hold harmless Owner and Owner’s management agents from any suits, actions, claims, losses, damages, and expenses (including reasonable attorney’s and court costs) and any liability whatsoever that Owner and/or its management agents may sustain or incur as a result of tenant’s failure to move out and continued use of the premises.Let me know if there is any other thing I can do to address your concerns.

Dont waste time with radiant barriers unless you are very sustainable.

But a charity still needs to be able to sustain itself. ;-) Again, I digress...

Not sustainable for folks.
