A home that is selling for $100k after we just saw the biggest run up in real estate values in my adult lifetime means that it's probably not a very desirable place to live for people that have options.

I think your approach is probably a good one for the adult child. 

Hello All,I was wondering if any others have experience with owning a rental property that is an adult family home by renting out the rooms?

(senior assisted living, special needs adults, or halfway house)To clarify, I want to be only a landlord and lease to an operator who runs ____ business.

I found this odd, so I decided to call Cobb County and they advised that a basement can only be rented by one adult with some kind of square footage per person limitation, and I could not wall off the basement door.

Most of my adult life was spent working as a Firefighter/Paramedic.

One question is liability and insurance, also what if the 'adults' (ie couple on the lease) leave and all that remain are the students? 

They need to be adults.

For example, I mention that every adult must pay a $30 application fee, pass my credit/criminal background, make a combined income of 3x the rent, and whether or not the property accepts pets.

Know that children are rough on properties versus older adults with no kids.
