Property listings by agents

[Brandon Gamblin]

What does it take for an agent to list the property? When an agent lists a property, what happens or what takes place? Whats the process? I'm asking because I had a friend who agreed upon a price with a seller and the seller took the contract to an agent, the agent listed the property and the deal, according to him, died. Is there any way we can prevent this, as wholesalers from crashing our deals? How can we learn from this situation?
