Realtor fees when I bring the buyer to the table

[Harold Groetsema]

I have a question that I'd like to ask. I as a flipper worked with a realtor that charges me 4% commission when I sell my flips. If I bring the buyer to the table to purchase a property even before I purchase it to flip for said buyer, would I still have to pay 4% commission or split the commission with the realtor? This would be the 3rd deal that we have done together.
