What should I make of a Canton agent who has almost no online reviews but says they get everything by referral?

A referral-heavy Canton agent with few online reviews is not automatically a red flag, since some experienced agents genuinely close most of their business through repeat clients rather than online leads. Verify the claim independently instead of taking it at face value: ask the Georgia Real Estate Commission license lookup for how long they've been licensed, and ask for the addresses of two or three recent closings you can confirm through public records. A legitimate agent will hand those over without hesitation.
