Should I work with buyers who want to purchase off-market deals?

[Dylan Kiley]

I'm working with a buyer who's looking to purchase off-market deals. I got an email from a wholesaler who has a property that meets all of my buyer's criteria. Who would pay my commission in this case (the seller, wholesaler, or my buyer)? How can I ensure that I'll get paid before I present my buyer with the deal? The last thing I want is for him to go behind my back to avoid paying a commission. Is there a form that I can have my buyer fill out that entitles me to a commission on an off-market deal (like a wholesale deal) before I present him with the deal?
