Jimmy, all commissions are negotiable, and it is improper for any agent to discuss specific commissions in a public forum.
Interview a few agents...... see what they charge, and what their marketing plan will be.
Ask for it in writing.
Compare and contrast what they are offering.
My advice is to focus on the agent.......... their experience and knowledge of your area, and what efforts they will make to get your home sold. Ask what their track record is.....what percentage of their listings sell.
While I understand that the commission is a concern, shopping for the lowest one might not be in your best interest.
There are also flat fee brokers you might want to investigate.
As far as who pays the commission - that's an often discussed/argued point here on trulia.
On the basic level............. the seller pays the commission. The sellers sign a listing agreement in which a commission is stated - to be paid when a buyer is found.The listing agent usually agrees to share that total percentage with any agent who brings in the buyer.
The commission is paid at closing, and taken out of the proceeds of the sale.
So, on the surface, the seller is paying the commission.
Now, here is where the discussions come up............it is believed that, in reality, the buyer is also participating in paying the commission, as the final accepted price is most likely factoring that in.
Without a commission the buyer most likely would be able to purchase the home for less. So, they are certainly , in effect, paying the commisson along with the seller.
