Some Attorneys said wholesaling is illegal , why?

[William Laurent]

Hi, I'm William Laurent, a wholesaler in Miami, Florida. I need you help with something please, I was trying to review my contracts with an attorney here in Florida, and most of them told me that the process of sign and purchase and sells agreement with a seller in xxx$ amount and then assign the contract to another third party (investor) for a different xxx $$ amount is illegal and consider like a fraud. I was studying and preparing myself and have clear the wholesaling process and now different attorneys here told me that. I know that Wholesaling is a old and very common strategy in this business but why there is attorneys who said that is illegal? How can Explain to this attorneys that this strategy is complete legal when they are attorney and know the law? Thanks, I really appreciate all your comments attention and help with this issue. Have a great day. Regards.
