Who are great property managers in Atlanta you would recommend for my circumstance?  

Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

Any referrals or recommendations for good and qualified brokers, sellers, property management companies, loan brokers, insurance brokers, mortgage brokers, contractors, etc.

If you are new and don't have a clue, then I would certainly recommend them or some company that can guide you through things until you have an understanding.
