Yes, all adults get to be screened before moving in.

As soon as she was a day late you should have started the eviction.... start it tomorrow, you'll feel much better.You OOS Investors need to learn day 1 that Detroit tenants will F you in a second - they know the system and are good at it... old, young, male, female. 

Credit and background search each adult tenant that will be living in the unit.

@Rhiannon Then Definitely run a full credit, criminal, eviction check on her and any adult over 18 that will be living there.

If somebody didn't qualify on their own, as a grown adult with their own income and their own references - I didn't want the job of teaching them how to be an adult or to give them their grown-up consequences for being a grown-up adult who didn't act like one in my building.Just say no.  

Whatever your tenant is spending his money on as a priority other than rent - which is always my personal #1 priority - is his big adult boy lesson to learn and not your problem.
