Payout for Realtor Finder Fee

[Joseph Milano]

I am currently researching different marketing strategies in generating leads for wholesaling, and utilizing some of my current relationships with realtors seems like a great place to start since it doesn't require any upfront out of pocket cost, and I have worked with them on deals in the past.

That being said, how should you go about paying them any finder fees for off market deals? Should it be apart of the assignment contract and paid out at closing? A separate contract all together? 

Also, what is anyones experience finding deals this way, do you lean heavily on this as a strategy or something that only produces a deal or so every couple months?
