I would probably be very nice and try to grab empathy by using vague words (such as fairness, etc.), asking the real estate agent to 'help me out', and explaining things in terms of feelings. Hopefully, after the initial discussion, I wouldn't have to keep doing this over and over again, but even if I do, this has the advantage of seperating the "persuade real-estate agent to keep working with you while not signing a contract" from the "get information" part, and so is probably less likely to distract me from the important bits.

I don't think this would be terribly hard for me. I'm trying to think of possible explanations for this, but none of them are feeling like they model my internal mechanics well.

Disclaimer: I have never actually worked with a real estate agent.
