You believe you have to prove the last agent got it wrong, so you go looking for the bad photos, the price history, the days on market. He never mentions the other agent's work at all, and he never asks for the listing — he gets the seller to say out loud that nothing new was ever put in front of them.
The seller has told him he is putting the house back on the market with the agent who just failed to sell it. Most of us hear that and start listing our own advantages. He asks the seller one question about the meeting that already happened, and rules out the only answer that agent probably gave.
Him: "Outside of begging you to lower your price, what did they say they were going to do differently?"
Him, before the seller can answer: "Be honest. They didn't show you anything, did they?" ... "Tell me I'm wrong."
Seller: "No, I can't argue."
Him: "Now, Luke, if that's if I'm right, don't you owe it to yourself to at least get a second opinion?" ... "I'm not asking you to hire me. I'm not asking you to make a decision." ... "Tell me that's a horrible idea, I will hang up and leave you alone forever."
Seller: "I can't say no to that."
Watch what the first question does. It takes the price cut off the table before the seller can offer it, so there is nothing left to put in the blank, and the seller reaches that conclusion himself instead of hearing it from a stranger. Then the ask drops from hire me to hear a second opinion, and the exit he offers — tell me it is a bad idea and I disappear — is one no reasonable person takes. He names the whole approach at the end: "That is reverse selling."
“Outside of begging you to lower your price, what did they say they were going to do differently?”
The re-list objection feels final because it sounds like loyalty, and loyalty is not something you can argue somebody out of. But it is rarely loyalty. It is a seller who does not want to start over and has no evidence that starting over would change anything, because nobody has given them any.
Criticizing the last agent puts you on the wrong side of that. The seller then has to defend a decision they already made, and people defend those decisions harder the more you push. Asking what was offered instead of what went wrong moves you out of the argument entirely. You are not the person attacking their agent, you are the person who asked a fair question they could not answer.
