Young adult children cost a lot of money compared to ages 1-18.

I am going to walk away and tell an adult."

Seriously, with everything else that goes on with seniors and their adult children, at least that's somewhat taken care of.

@Julie VerardiYou can do a co-tenant lease addendum for the adult child if they are living there, versus just visiting while school is on break.

I would write a cover letter and create a Tenant Information Form , then ask all adult tenants myself for the information.  

Your going to find that it's not your typical family of 2 adults and 3kids.

On the other hand, I definitely would not have been open to renting my house out to 3 adults and 2 children in a home that only has 1 tiny bathroom!

With 6 it is pretty clear but what if it is 4, two adults in one bedroom and two teenagers, a boy and one girl in the other?

With a few exceptions, the maximum number of adults that a landlord may allow to occupy a rental unit in Texas is three times the number of bedrooms.

I don't charge an application fee per se; I tell the tenant that if I approve their application based on their employment and rental history, I will then run a background check at $25 per adult applicant.
