I personally know an instance where they pretty much drove one of the landlord's to their death from all the stress.

One scenario that could have happened is that Neil didn't make some of the payments prior to his death.

You've beat this "under market" thing to death.

And if you knock her up before you’re married, I’ll drag you to death behind my car.

He was deathly afraid of lawsuits or even eviction court, and wanted me to back down.  

If you roll it into the overall rent, they won't know the difference and they'll feel grateful to live in a place where the landlord isn't apparently nickel and diming them to death.  

C of Os usually list bedroom location and numbers by floor. if a C of O does not list (nor was amended to show) bedrooms in the basement, they are illegal.not only do conventional lenders practically never count rental income for a single family primary residence, but similar issues arise when doing taxes - unless the local zoning particular to your property allows ADUs and was done with proper permits etc or u are only renting out legal bedroom/s to lodger/roomate/s (ie, basement 'bedrooms' are often illegal and a huge fire/death hazard).

Chris Mason After I started this thread I found a list of dog attack deaths on wikipedia. 

I also doubt that a natural death needs to be disclosed to any future renters. think of the millions of houses that this has occurred in.

Something like knowing a balcony on the 12th floor wouldn't hold any weight, and renting that unit out anyway, which resulted in a death you could have prevented.
