Thanks for your replies. We are only wanting to restrict the age of the leaseholders. Some of our communities are 20+, some are 21+ (age to sign the lease, not to be an occupant). Since this is our first property in TN, I didn't know if there was a local or state law disallowing this practice.
For example, at our 21+ community, we would not allow an 18 year old to rent the unit alone.
Does that make sense?
