When and how do realtors get paid in a wholesale deal?

[James Popp]

Besides the fees, do they get paid commission on what I "buy" it for? Or do they receive commission on what my cash buyer buys it for? If it is the latter, then shouldn't realtors really want to work with wholesalers? 

I've just heard about this stigma with wholesalers and realtors and I'm just trying to wrap my head around why, and how I should convince them to work with me.
