It is possible to negotiate on commissions. It's worth seeing a few agents in your area to see what they are including in their commission rate as not all agents structure their fees the same way. For example some agents include some advertising as part of their commissions rate. When comparing agents, look at their past history of sales and experience to see if they are right for you. You might be willing to pay a slightly higher commission if they have a proven track record of selling above market rate. As mentioned above, tiered commission rates are also a great negotiation tool to get you the best price result on your sale.
