Multiple Listing Service Of Southern Arizona

What Multiple Listing Service Of Southern Arizona does

MLSSAZ is the Multiple Listing Service for Southern Arizona, operating as a wholly-owned subsidiary of the Tucson Association of REALTORS (TAR). Founded in 2001 and headquartered at 2445 N. Tucson Blvd in Tucson, the organization serves approximately 7,000 real estate professionals — agents, brokers, and appraisers — across Pima County and surrounding communities including Green Valley, Sahuarita, Marana, and Oro Valley. As a cooperative real estate database, MLSSAZ functions as the regional infrastructure for listing data sharing, with mandatory NAR Clear Cooperation Policy compliance driving participant participation. The organization is governed by a Board of Directors comprising representatives from major regional brokerages and staffed by approximately 7–8 named personnel in executive, IT, data integrity, communications, and member support roles.

The core technology platform is FlexMLS, which provides listing search, management, statistics, and member dashboard functionality. The Supra eKEY mobile application and iBox BTLE Bluetooth lockboxes provide electronic showing management as separate revenue-generating products. MLSSAZ offers IDX feeds via the Real Estate Transaction Standard (RETS) for agent and broker websites, and ListHub syndication distributes listings to Zillow, Trulia, Yahoo Real Estate, and AOL Real Estate at no charge. Recent product additions include Realtor.com+ (launched April 2026 as one of the first 16 MLS partners), Solid Earth Secure Single Sign-On with passkey authentication (deploying spring 2026), and Clareity MFA (implemented May/June 2025). Additional integrations span RPR, Realist, Showing Time, BrokerBay, Greenlight, CRS Data, RatePlug, New Home Source Professional, and Transaction Desk.

Revenue mechanics rely on annual subscription fees from participants and subscribers (pro-rated by join month, renewing each July), separate Supra lockbox hardware purchases (one-time $124.57 per iBox BTLE) and monthly eKEY subscriptions ($21.20–$28.69), FlexMLS-billed IDX SmartFrame packages starting at $349/year, and Board of Choice administrative fees ($10 one-time) for members holding primary membership at other associations. The go-to-market motion is membership-driven through TAR and GVSAR association partnerships, supplemented by the MLSSAZ website, monthly newsletters, training webinars, and partner-driven awareness through technology integration announcements.
