Question about my buyer coming with a realtor and Commision fees?

[Cass R. Smith]

This is new to me because I normally have investors who look at my wholesale deals but I've gotten to calls from buyers who want two actually live in the property and fix it.  How does it work with commision fees?  I've had one realtor ask me if I was ok paying a commision and I was taken back?  Sorry if this is dumb question.  Just looking for a little insight on if I should steer away from non investors or what.

Thanks
