Commissions.
(E) Commissions. A right to payment of a commission, brokerage fee, or similar charge for professional services rendered in connection with the arrangement or financing of a purchase, sale, or lease of real property does not constitute a right to share in the appreciation in value of, or gross or net proceeds or profits of, real property solely because it is based upon a percentage of the purchase price or rent. Thus, a right to a commission earned by a real estate agent based on a percentage of the sales price does not constitute an interest in real property other than solely as a creditor.
