Wholesaling with a Broker

[Rainiel De La Nuez]

If I am direct mailing and finding deals which I put under an assignable contract between the broker and the seller will do I need an RE licence? Am I acting as a broker's agent? 

Can I place a deal under contract and assign the contact to a brokerage? 

Can the broker then turn around and market the property and assign the contract again?

I am trying to find how other wholesalers may be structuring their deals with a broker involved.
