So if they have a fight and he punches a hole in the wall and then your tenant doesn't want to pay for it (she sounds a little snotty from your post, I could be wrong!)

This is just a piece of steel with a slot in it that screws to the wall or the floor at the back of the stove. 

A lot of properties I look at have, over the years, had walls moved or other modifications.  

Many people on the forums do not care for Wall St. investment products, and that is certainly their prerogative, I will not stoke that debate.

Especially on older walls.  

If the heat was turned off while you were gone or water lines are near/on the exterior wall they can expand in the cold breaking the weakest point and when it warms/thaws out is when you find out about it.

It doesn't care what color you are, what you cook, your tattoo's, etc.

Put them on the wall and hand them out to prospective tenants that are there.
