It is simple in my opinion:
An Intown Atlanta Agent/Brokerage
Innovation- Many agents use the standard I list your home, do open houses, do brochures, do flyers, email blasts, etc. But what do they differently that makes them stand out? How do they think outside of the "real estate agent" box? Make sure they see your home as unique and individual and provide ideas and marketing strategies therein. Everyone has a binder or a power point that looks pretty but what can that agent or team do specifically.
Track record of team and/or individual agent success
Most importantly, you should be able to have a very communicative relationship where you can always express yourself to the agent and understand the agent can and will express themselves to you.
Save the "friendship" until the home is closed. Agents and Clients are friendly with each other but need to remain aware that this is a legal transaction and should be handled accordingly.
