Everyone on here is correct we can't talk about others fees and it is all negotiable.
I do see this question come up quite regularly on Trulia and I always have the same response. Interview x amount of agents until you find one that works well with whatever you have defined as your expectations for this transaction. Every seller has their own variables they highly value and it is just a matter of finding a realtor who fits that description. Then, the commission is something you talk about and both parties agree to it.
Your zip code is in my primary area so I would certainly love to be one of those agents interviewed. If you contact me directly we can talk about what I charge.
Good Luck Michelle!
