Tons of trash left in the home and in the garage along with personal possessions - toiletries in bathroom, decrepit looking washer and dryer in basement (not hooked up and seemingly long unused ), old couch, old truck tires, vehicle battery, TV stand, mower and vac in garage. 

As I get more properties I care less about rehab speed and more about my mental health and stress levels 

He's 72 old with health issues but unsure if happens something to him or if he just decided not to come back to the U.S.A and just stopped replying to me.Rent was due on August on 14th and past due now.

The health and well being of the families residing in your property is at stake.

If I had a tenant who was medically compromised to the point of being a serious health issue I would consider a hotel stay.However, having grown up in San Antonio from 1st grade thur 11th grade with no AC in the house, i am less sympathetic in giving hotel assistance to my tenants.  

Tenants claim they are abandoning the property and will not pay rent any longer now citing health reasons. 

Another more expensive option is to have a keypad with multiple pins, that would cost more to setup and batteries would need to be changed too.Let me know what you do, thanks!

However, he has been demonstrating concerning behavior and I have been told he is currently in a mental health facility.

I currently work in health care profession so i plan to do mid term rental to nurse. i am currently sub-lease my apt so my rent is less than $500.

But it will cover battery-storage technology (up to a certain capacity).
