Commission rates are set within an individual office, not between REALTORS. Many things are considered when an office sets their commission rate such as the average "cost of sale" for a property, such as advertising, cost of all overhead, cost of gasoline where listings are far apart as in rural areas and the commission split between agents and agencies involved in the sale. A commission is split sometimes four or five ways, ie, a percentage to the listing and selling agents, the listing and selling offices, through MLS, and sometimes a referral. If one understands how the money is divided, it's easier to understand the fee. Rates can also be negotiated at the time of an offer, between the Agent and Seller, (or Buyer, if the Buyer is paying the fee) to be able to put a transaction together. Commissions are seldom considered a "fixed" fee, at least not in my past experience. Cut Rate Commission Offices may work on a scale, depending on the amount of work they do for a Seller.
