History of MLS

A multiple listing service is an organization of real estate professionals who agree to cooperate and compensate one another in order to better assist their clients with buying and selling real estate.

Northwest MLS

NWMLS was formed in 1984 when four Puget Sound area MLS groups merged. Our name changed in 1996 to Northwest Multiple Listing Service to better reflect the growing geographic area we serve. We are one of the largest multiple listing services in the country, providing full member services to 28,000 real estate brokers in Washington State.
