We currently have a mom/stepdad and daughter/significant other living in one of our rentals.  

We've had one bad tenant, and even though she chased her own daughter around the front yard with a hammer, she never bothered us.Post application, I feel fairly good about our tenants, and that really isn't so much the impetus for this thread; it truly is the pre-screening process. 

Her daughter (tenant) had a falling out with her roommate and went home mid-semester.

I left the voice mail and she never ever response my call.Finally, my father drove 8 hrs to there to check if she is ok or not on 8/30/16.He went to management office first then went to condo.He heard there were someone talking inside the condo, so he knocked the door and my tenant  opened the door.My father felt better because she is ok.We ask her why she didn't response us, she didn't answered.We ask her to pay the August rent because if she didn't pay on 8/30/16, she will get late charge for $100.We know her health is not good so we asked her if she has personal check.She said that she didn't have personal check.She would go to bank next day and give me a call after she finished doctor appointment (8/31/16)My father was worry about her and asked her if she needed a ride to hospital.She said her daughter would take her to the hospital.She still not call me and response all my calls.Can I evict her out?

Oh, and if there isn't a better alternative, my daughter let her tenants pay her with PayPal.  

When my daughter rented out her first home, she was surprised that there wasn't much of a change in cost.I'd rather have my own insurance, in case I had to fight with AirBnB.  

My daughter had a similar scheme happen to her with a PM, and this tact worked with them.Next, your contract probably says that if the place is ever deemed uninhabitable, that the contract is void.  

Told her who I was and that I was concerned, not being able to reach her daughter.

I have a tenant, married and retired couple,  who have a grown daughter (aprox 30 yrs old) living with them. 

My daughter has quietly lived in a duplex for over 2 years but new neighbors who smoked weed moved in next door.
