how does the realtor get paid in owner financing?

[Kevin Hart]

hey BP'ers, 

I found a deal for a 6plex, motivated seller ready to retire and not deal with tenants anymore. They are interested in owner financing (they like the idea of using this basically as an annuity for 3-5 years). All the numbers look good, but myself and the seller have realtors involved, so how does the realtor typically get paid on this? will myself or the seller have to come out of pocket for their commission?

obviously ideally, i would have found this property on my own and wouldn't have had realtors involved, but I didn't know owner financing was a possibility until i happen to meet the owner while my realtor was showing me the property. 

any clarity would be much appreciated. thanks!
