I would recommend Academy Properties. They are located in McDonough and are a member of NARPM (National Association of Residential Property Managers).
Ask for Earlene Gardner, phone # - 770-957-9550 or email : firstname.lastname@example.org
Whoever you decide to use, make sure they are a NARPM member.
