This is not unethical for one reason – it sounds like you are open to selling the home at the inflated price if you get an offer. Were you to list with no intention of selling, that would be unethical. How is this any different from the thousands of realtors out there who are representing sellers with inflated prices? Based on the definition of unethical below, I’d say you are in the clear so long as it is a widely accepted practice for realtors to 1)Represent sellers who want to sell at inflated prices and 2)Benefit from the traffic at open houses and phone calls to drum up additional business.

unethical = not conforming to approved standards of social or professional behavior; “unethical business practices”
