They are adults who signed a lease.

He's was an adult, I use that term loosely and not sure of details.

I've been a contractor for most of my adult life (62 years old now), I have my Real Estate License, as well.

This is a good example of why going forward you make sure all unrelated adults over 18 are qualified individually (I state unless a dependent on another applicant's tax return, but background check still required), and a criminal/background check should have told you he has a current record so would not have been a good candidate for a tenant to begin with.    

My adult daughter loves English Bulldogs, and I know how much she's spent on them in the past! 

If you're renting to young adults who are transient, you'll probably have a lot more turnover than if you're renting to people in their 50s & 60s, etc., etc.As others have mentioned, it's also common practice to have open lines of credit ready for emergencies. 

Hi, I have a potential tenant that has told me she has 3 grown children all attending different universities within our state. Would you suggest doing credit checks and charging the fee for each one of them? I’m sure ...

Carla and Bob are adults – in fact, middle aged when they made their purchase.

The couple was in their late 40's, had adult children, and would be moving in without any other occupants.
