Selling a property that is listed in Zillow

Hi, I'm William Laurent, I'm a wholesaler located in Miami, Florida. I'm working in two deals, and I have a question. I would like to know if someone can help me with this please. I' working in a Co-Wholesale deal, And the subject property is listed on Zillow. if the property is already listed on Zillow the investor should go directly with the owner or agent who list the property right? Also if I sign an affidavit with the wholesaler, I don't have any spread to include my commission, because the property is listed on Zillow with the same price that the wholesaler is selling the property. What I should do in this case ? There is a thumb rule for wholesalers, that said we can work a deal that is already listed in Zillow ? How do we work as a wholesaler, with properties already listed in Zillow or MLS? Thanks so much, I Appreciate your knowledge, experience, and comments about it. Have a great day.
