Do you go after your realtors commission?

[Minna Reid]

I'm about to turn over my rehab to my realtor next week. Hardly any action on the fsbo, which is ok I guess, since I AM STILL NOT COMPLETELY DONE YET!!!
Anyway, this is the realtor who sold me my first two homes, is absolutely excellent, and I dragged her out to show me all the dumps on the mls, before I realized there were no deals on the mls and went off yo find my own deals. She has always helped me out with comps, etc.
At the same time, I'd like to save a buck. Do I go for the discount or no? Will I get less service for a lesser commission? Should I pay her her full fee, because she does go absolutely out of her way for me, even when she makes nothing out of it?
