I feel like they are mis-using the clause to make me take care of expenses they were required to pay when they foreclosed.Am I dreaming?

Matt I know I misused the term, basically what I mean is the house still has a bank mortgage against it.

So I personally have in my lease that any damage caused by tenant neglect or misuse is their financial responsibility.

I only harp on it because that messaging confuses a lot of people and people are misusing the words. 

(Some) Leaks: You are responsible for leaks caused by misuse or neglect (such as knocking drain lines loose).

Not to mention that intentionally misusing federal insured mortgage funds is mortgage fraud. 

Just put in the lease that proper  use  of fixtures is on them for any items attached to walls and you aren't liable for misuse.

Main point is that both situations are serious fire hazards, when significant and blatant misuse of illegal sleeping areas/room are made from structures not designed for that high capacity of use. 

House hacking is when you live in the house, and you can get in trouble for intentionally misusing a loan based on owner occupation.

I wonder if I can put a clause in the lease contract to hold the tenant liable for misuse.
