How can I judge a Kennesaw agent by the way they handle a post-closing possession request?

A good Kennesaw agent treats a post-closing possession request as a negotiation that needs clear terms in writing: a per diem rate, a firm move-out date and a remedy if the seller overstays, rather than a casual favor worked out verbally. Watch whether they protect your interests specifically, not just get the deal to close, and whether they loop in the closing attorney on the actual language. An agent who handles this carefully is usually just as careful with the rest of the contract.
