X would like to find new boyfriend to move in with because she can then rent the whole square footage and possibly pocket as much (or more) than section-8 pays the owner for the unit.The rooms may or may not come with stove privileges (at an extra cost).The subletors must (keep their heads down) at the rental and not be a problem (while there) and pay on time. 

Usually the issues are boyfriend/girlfriend issues including some that may be gang related.

My boyfriend later moved in with me into the second home and about a year later we got married.It is my understanding after talking to a local property lawyer that because 3 requirements were met, the rental property is still considered mine as a sole owner (the 3 conditions being: 1- asset was purchased before marriage. 2- we never lived there together as a couple. 3- all income & expenses for the property were kept separate from joint funds and are easily accountable). 

Why don't you try to go after her spouse or boyfriend as well, if he caused the damage?

I have a good tenant that wants her boyfriend to move in.  

Let's imagine someone owns a rental in the state of Pennsylvania, which is inhabited by a couple (boyfriend and girlfriend) and the girl's child.

My boyfriend bought our first live-in flip property and I want to move in to this house with him.

One couple bought a house, and 2 moved in with boyfriends.

A resident called me and asked me to come unlock her apartment, I asked her where her keys were, she said they were in the tree, she threw them out her window to her boyfriend but they got stuck in the tree 40 feet up!

I house hacked a SFH for 3 years, and my boyfriend just purchased a home for us with a VA loan, so I know a bit about the process.
