A Seller Says Another Agent Is Cheaper. Let ChatGPT Push Back.

The seller says another agent will do it for less. I practiced the answer out loud with ChatGPT's voice mode in front of a room of agents. Here is the prompt I used.

The seller says another agent will do it for less. Most of us have an answer ready. Fewer of us have said it out loud to something that pushes back.

In my AI class at the South Bay Association of REALTORS on October 28, I opened ChatGPT's voice mode in front of the room and had it play that seller. I gave it a voice that sounds a bit like Jarvis from Iron Man. That was the easy part.

## The prompt

Here is the prompt I used, word for word:

"You are a homeowner interviewing me to sell your home. Another agent offered a lower fee. Ask me why I'm worth hiring. Ask one challenging follow-up, then tell me one specific thing to improve."

## What it asked

The first question came back blunt: "Another agent says they'll do it for less. Why should I pay your fee?"

My answer in class started with the honest part. No agent can promise a price. What I can promise is "a verifiable process that will help you sell your property."

Then it came back at me. How do you prove those results came from your process, not a hot week in the market? That's the follow-up to be ready for.

## What it told me to fix

The coaching was specific. Name a verifiable outcome or process you control, not just years of experience. That is a fix you can practice before the appointment, which is the point of running it.

In class I said it plainly: no one really engages with voice mode for this. Take a question you couldn't answer, or a listing you didn't get, put it in a scenario, and let the AI push.

## Setting it up

Open the ChatGPT app on your phone and start voice mode. The first time, the app asks for microphone permission. Free accounts get a daily voice limit, and OpenAI says that limit can change, so check your own account. Paid plans get more.

You can pick a different voice. I picked one that sounds like Jarvis, which is the only reason I needed.

## Privacy for practice

Run practice with made-up details. Don't use a real client's name, address or numbers in a roleplay. Voice mode has its own training control, separate from the text chat setting, so check that too.
