Land Sale Realtor question

[Rodney Crawford]

I am in the process of trying to sell a piece of land in Colorado and was showing the property on my own for a few months as for sale by owner, I am not an agent, but then about two weeks ago I engaged a realtor. I had received an offer before working with her that was extremely low. That same buyer has come back now, she re-showed the land to him and he made another offer we are considering.

The question is should I give her full 5% commission on this and/or is it appropriate to negotiate the commission payout due to working with the potential buyer previously, or completely negate the commission payout? Thanks for your time and opinions.
