paying an agent on contract for deed

paying an agent on contract for deed

an agent sent me a contract for deed that was listed and i actually got the offer accepted using $100 earnest money and no money down,, i just dont know how to "pay" my agent for bringing me the deal. i am assigning it to a local landlord for $3,000 should i send the agent some money from that? is that even ethical?
i know the agent will get a commission in 5 yrs when the contract balloons, i just want to do something in the mean time.
