Disability

...you should use the come-back I used when some solicitous real estate agent asked me a similar question over the phone during the 2021-2022 real estate frenzy:

"Yes, we'll put the house up for auction. There's a starting bid price of $500,000 and bidders have to pay a non-refundable administrative fee of $100,000 which does not apply to the purchase. The $100,000 from each bidder is due in cash at my bank in my account the morning before the auction. Cash bidders only; no mortgages; payment due by wire transfer to the title agent at closing. No fee to any real estate agents."

All I heard from the real estate agent was, "Oh, thank you for the info."

Problem solved; never got another call like that one.
