Real Estate Commission Clause is an agreement between a buyer or seller of a property, and the real estate broker or agent, that sets out the commission that the broker or agent will receive for acting as an intermediary in the transaction. There are two types of Real Estate Commission Clause: Fixed Rate and Variable Rate. Fixed Rate Commission Clause is an agreement that sets out a flat commission rate that the broker or agent will receive for the sale of a particular property. This commission rate is usually based on a percentage of the sale price of the property. Variable Rate Commission Clause is an agreement that sets out a commission rate that is based on factors such as the size of the property, the location of the property, the type of property, or the length of time it took to sell the property. This type of commission rate may be adjusted depending on the circumstances of the sale.
