In this situation, you want to stay positive, then ask if they’ve signed a contract yet. If they have, wish them luck and offer your services in the future for advice or for referrals. If they haven’t, then go into this objection handler:
Homeowner: We’re going to re-list with our same agent.
Agent: OK, I completely understand that. Can I ask you a question, though? Why do you think you’ll get a different result doing the same thing? What is your agent planning on doing differently this time?
Wait for response.
Agent: I get it. They seem really nice. But here’s an idea. If you have 15 minutes, I’d love to offer you a second opinion on selling your home for more money and less stress.
