Also I enjoy the social cause behind helping Class C tenants experience a enjoyable renting experience.

I define over extended that a scenario such as the Great Recession (GR) that had many markets suffer large RE price declines and increased vacancy/lower rent would cause you to either sell or default. 

As a landlord, you bear liability for injuries caused by unsafe conditions (or at least that's what attorney's advertise).  

It doesn't matter who caused the damage; they are all responsible for it.

If the company comes out again, ask them how they installed it, what is the root cause of the issue, and where in the manual it says the maintenance they are suggesting you do.

Anyone would notify their landlord of a typical water leak since nobody wants water damage but something like this isn’t really noticeable to the tenants or causing damage so they might not care.

@Jose De La Macorra sounds overly complicated and there are probably many ways this could go wrong: everything people have mentioned above like healthcare costs causing problems, unknown heirs or past business partners coming out of the woodworks with title claims... plus if he dies next week in a freak accident that doesn’t look great for you either if you benefitted financially from his early death.

With this much activity there must be something everyone is noticing that is causing the vacancy.

I think the buttons are less likely to cause issues. 

Cause me and the sellers were at 10k difference in the purchase price point.
