I had an ad FSBO and was getting calls. An Agent then put his ad in and it replaced mine. Our ads are different because he wants to low list it so as to attract competition, but I want to show the price I will accept. I cannot remove his ad, tho can denied his ad as not mine. Effectively this has blocked my advertising. MY contract with the agent is based on his bringing me a buyer, so he does not get paid if a buyer approaches me.
