The difference between salespersons and brokers

Before the Multiple Listing Service (MLS) was introduced in 1967, when brokers (and their licensees) only represented sellers by providing a service to provide legal documentation on the transfer real property, the term "real estate salesperson" may have been more appropriate than it is today, given the various ways that brokers and licensees now help buyers through the legal process of transferring real property. Legally, however, the term "salesperson" is still used in many states to describe a real estate licensee.
