This is causing me Additional stress which affects my underlying condition to progress faster. 

COVID has caused a supply issue for our MA market.

In one of the better scenarios, a sloping floor could just be caused by something as basic as improper installation of the flooring.

If there is a hailstorm, as a landlord do you reach out to your tenant and ask if everything is ok? Or assume it is if they don’t reach out?

I would assume young, not-yet-trained pets would cause more damage as well (I've not had any of those yet, but I've had my own puppies)But here's the thing, too - young kids probably cause more damage than most pets.To answer your questions:- I don't think there are any laws against discrimination against pets? 

I own a single family property with tenants, and this past year I poured a lot of money into the property after I had family cause a lot of damage to it.

The tenant though has to give compensation and not cause damage beyond excess normal wear and tear. 

If you’re gonna sub anything out it’d be electric, cause you can die doing it lol.

Without even knowing the exact demographics of the income or crime in the neighborhood that could cause it to be a risky investment, the median price of sale in this neighborhood of Mill Hill is 29.5k.

However, I wanted to get insight as what problems this may cause in the long-term (if any) once the current global situation is resolved.
