Tenants are adults, not children. 

@Ted Klein combine income and put all adults 18 and older on the lease jointly and severally.

There's no way I'm taking that person beer to schmooze them into behaving like an adult. 

I wouldn’t over-complicate a roommate situation and typically if they are normal human beings, they will be ok sharing responsibilities for shared items like cleaning products, toilet paper, etc and you can split those costs like adults.

Find your county's court record website and look up every adult applying for a rental for criminal and/or court records.

I do feel like anyone who would rent to this person needs to know that they simply do not know how to clean and live like an adult at nearly 30 years old.

How many people (adults & children) will be renting this suite?

If vacancy is high because your metro overbuilt a little, some young adults delaying their entry into housing, or increased roommate activity then this facilitating of A <- B <- C will be met by lower rent and eventually (and friction makes this a slower multiyear process) the vacancy will fall most of all on owners who aren't motivated enough to cut rent to avoid some vacancy, but also will increasingly get shifted down to the worst C properties (which makes sense when you think of where long term vacancy ends up in metro's with higher overall vacancy rates... its always in the absolute worst neighborhoods). 

Shows credit, ok, shows judgments, payment history and says NO convictions.For kicks and giggles, I googled him a few minutes ago and BAM, he was charged  with sexual misconduct with a minor child in March 2018.  

Also any kind of sexual molestation or theft.
