What mandates how much a real estate broker can charge for a commission?

The correct choice reflects the principle that real estate commissions are typically a matter of negotiation between the broker and the client, with no strict regulations dictating specific commission rates. This allows for flexibility in pricing, enabling brokers to adjust their fees based on various factors such as market conditions, the value of the property, and the specific services offered.

While some organizations or associations may have guidelines or best practices regarding commission structures, they do not impose mandatory rates that brokers are legally bound to follow. This lack of a mandated commission allows for a competitive environment where brokers can tailor their services and fees to attract clients.

In summary, the absence of specific mandates from organizations or laws about commission rates emphasizes the importance of negotiation and market forces in determining how much a broker can charge, reinforcing the answer that there are no mandated commission structures.
