Tenant in Hospice, will soon die

[Angela Liu]

I have an older 70+ gentle man and younger 50+wife renting my house.  Old man was in & out of Hospice.  Probably will die soon.  Wife is very upset because the A.C. was not working for 5 - 7 days while the old man was in hospice.  Monday, we called all retail store - cannot find any available portable Swamp Cooler.  Tuesday, Luckily we found a portable Swamp Cooler, delivered, installed before the guy arriving home from hospice. Wednesday, delivered an additional electric fan again before wife complaint not cool enough.  Thursday, finally technician went up the roof & fix the A.C.  (Technician was fully booked, and can't be there until Thursday. That's why we were trying to find the portable in the first place.)   Their rent is one-month behind.  Had been giving them 3-day-notice month after month since Jan 2016.  They refuse to leave.  I know that I will have to hire eviction lawyer and eventually they will win because of they are poor, they will have legal-aid.  Wife threaten to sue me for "Elderly Abuse".   

Need advice:

1. Did I do everything right?  Anything I missed?

2. Can tenant sue me because A.C. broke?

3. Can wife blame me on the husband's illness?  or condition deterioration?

4. How do I get rid of them?

5. If he died, what should I do?

6. Do I need to disclose to the next tenant?

7. Can I still evict them?
