My husband and I each work full time W-2 jobs, and the plan is that two of our adult sons will do a majority of the rehab work- but they can't start until June so we're just spinning our wheels. 

There might be some elements that light a fire for other RE investors though.I've tutored adults in math and accounting and discovered early that you learn more than the students.

That means it ain't your fault.I'd say ask your insurance agent if your medical and liability cover temp employees on premises if they are not insured or required to be insured.I have allowed teenagers to adults mow my grass for over 45 years, no problems yet!

I am a young adult and I have been pondering on real estate for quite some time.

I can't call until Monday, so I figured I'd try here for answers.How do I calculate the "number of adults living in the unit"?

There are six section 8 units down the street from us; 5 of those units are quiet, hard-working adults with young kids who behave BUT ONE unit has a family of the stereotypical section 8 tenants - they let everyone stay with them, there is trash all over their yard all the time, they usually have broken doors and furniture in front of the unit on a semi-weekly basis, and they even allow drug dealers to use their yard/corner for dealing. 

The house is a multi-use home because there is an adult family home business using the house.  

You're playing the adult real life version. 

Here's another opinion:  When you say 'child', do you mean adult child.  

Perfect for a single parent with one child, don't know about 2 adult non-related co-workers on a corporate rental. 4 feet is not very high; see for yourself with a tape measure.
