I'd stated the occupancy limit on the property is 4 adults and was a bit unprepared when he filled out the application with 6 total people (himself, wife, and 4 kids).

But I am an adult so I realize that it's the parent's responsibility to raise their little crotch goblin, not the landlord's.

Adults are expected to behave themselves.  

It is also reasonable to question the decision making of adults who smoke in the house when young children are present. 

Require renters insurance naming you as additional insured at the time of walk-thru, require valid auto insurance for all vehicles to be garaged on your property, video all walk-thrus, require only the paying adult or adults to be named on the lease, do not require all adults living in the premises to be on the lease.

I am VERY interested in Adult Foster Care/AFC.

@Bill Gulley - no worries; I'll settle for dinner and an adult beverage or two, should you find yourself in SW Ohio .... or we find ourselves in Springfield, MO. ; )

Do sellers have to be at closing via phone or webcam?

Quote from @Shivani Kumar: Quote from @Theresa Harris: If there are 10 adults living in a house, they should be able to afford the rent. 

Hi, I was recently reached out by someone who wants to rent my 3 br 1.5 bath and use it as a assisted living facility for adults.
