Why would they then not be able to pay $1300 per month for rent, especially with multiple adults on unemployment?

It is not up to me to tell adults how they should live their lives.

That could possibly mean 3 adults too.  

This is a simple task that most all adults fully understand.

If you’re looking for an adult who may have lost their job during this time, I would pay them closer to $10/hr and $2/per sign to help them.

I have contacts within the Dept of Children and Families who can assist with partnering to help young adults who are aging out of foster care system and have not been adopted.

A good example I read recently was a couple's adult daughter moved back in after a divorce and their condo they occupied was no longer big enough. 

It's a civil matter, meaning adults need to figure out their personal drama and let cops focus on more important things.I would attempt to visit with all three occupants and explain to the daughter that she is not an authorized Tenant and that her parents want her out.

It was also imperative, and the right thing to do, to only ask prospective tenants "how many occupants (as opposed to how many adults and children)" will be in the home.  

Have any of you experience with adult employed roommates, not 18-21 year old students?
