The agent isn't familiar with your neighborhood.
Just because an agent has sold houses in your city doesn't mean she can sell your house, too. Even very small cities contain areas that have specific personalities and attract specific types of buyers.
If you're in a neighborhood populated primarily by doctors, then you want to make sure the agent isn't afraid to let the personnel department of the local hospital know about your listing. By the same token, if your house is in a neighborhood coveted by artists and writers, make sure you're dealing with an agent who's comfortable posting a listing on Web sites or Facebook groups where buyers might be found.
But first, you need to make sure the agent knows the niche that feeds your neighborhood. "You've got agents who know some parts of the community but not others," Bilbrey says.
