Involve buyers agent in wholesale transactions?

[Jeff Fairchild]

I just had a broker email me. She has a client who is interested in one of my wholesale deals. What are the issues that I need to think about when allowing agents to be involved with my deals? I'm guessing I need to make sure there is enough profit to pay the agent's fee. Should I tell her that the buyer needs to use hard money or cash?
What about with regard to her contract vs. mine? What about else is there to think about?
