Mold has begun to develop in the drywall recently and I am concerned for my tenants health. 

Say the neighbors had health insurance.

Sixty days prior to me getting title, the health department took out 39 cats and when I opened the back door, there were at least another 15 cats still living there.

I would just speak to him and or family members and explain the exact situation and the dilema it is causing.....Assuming yes I think you can insist that he have a caretaker on the premises stating that he is unable to care for himself any longer without supervision and it is in fact causing a health issue with the building as well as other tenants.You don't want your tenants complaining to the board of health.Never a dull moment with a house full of tenants!!

Last month, she informed me she was leaving the PM company due to health issues and that another PM would be taking her place.On my first invoice under the new PM, I see a charge for $100.

@Sarah Maddox  Absent a local or state law to the contrary, civil contracts are generally unaffected by one's health situation and rightly so.

@Taylor KamalMold is potentially harmful to your health.

Both in the sense they harm their health (their choice, I do not oppose) as well as create an offensive and potentially harmful environment for those around (I very much oppose).Having said that, I still think that growing marijuana on a property is far more benign than smoking or keeping animals indoors.

At home I do not use Teflon pans due to the health risks .

Passive income for health care use!!
