About Us

History of MLS

A multiple listing service is an organization of real estate brokerages who agree to collaborate to better serve the public in all real estate transactions.

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 33,000 real estate brokers in Washington State.
