Also if she is leaving and getting her deposit back have you collected additional for the other tenant who will be staying to make up for the return to the roommate.

Sharing internet, is like being roommates. 

Set for life on audible (been in the FI space for a year) --> bigger pockets money --> bigger pockets...finally came around after my roommate told me about it, but FI is my goal so I'm grateful you (Mindy and Scott) have brought me into this world.

Very possible with a SFH and roommates or a MF.

The obvious challenges could be turnover, roommate issues and potential damages caused by late night "lifestyle" choices. 

If they have bad credit but have a cosigner or a responsible roommate, I am ok with that, but prefer a credit score higher than 600.  

I'd house hack right now... be it getting a home and renting our rooms, or a small 2-4 unit and renting out the units (and maybe getting a roommate). 

This will certainly cause a strain on her relationships with any roommates.

We all know not all tenants will maintain the home at that standard Esther L. says of her roommates, it requires a lot of work and attention to detail if it’s to be done right.I don’t agree with the suggestions to take over the Airbnb business because that would be creating a labor-intensive job for yourself, which this tenant is already doing.

If you are comfortable with roommates, it would be easy to house hack one of those.
