Wholesaling on-market propery

[Travis Hurst]

Good morning/afternoon. I currently have a property under contract that is currently listed on the MLS(at a wholesale rate less than the market price), but i was called directly by the seller. Do I have to involve the Real Estate agent that has the house listed or can I go directly through the seller because he contacted me? I would hate to set things up with my buyer and title company then find out I did something wrong. I need to know whether i can move forward right now without legal repercussion.
