Tenant wants to move in a coworker in need

[Gene Baldwin]

I have a tenant that has a coworker that is in immediate need of a place to stay. The coworker has 3 children. My tenant wants to let her stay with her until she can find housing. We recently bought this property, and have not signed a lease with her, so she is month to month. What would typically be protocol on something like this? We don’t mind helping people in need, but just want to know what would be good parameters, timelines, and fees? Thanks!!
