What Realcomp II does

Realcomp II Ltd. is a REALTOR-owned Multiple Listing Service (MLS) cooperative headquartered in Farmington Hills, Michigan, operating as Michigan's largest MLS with direct access to approximately 51% of the state's REALTORS and effective reach to 98% through data-sharing partnerships. The company is owned by seven Boards/Associations of REALTORS across Southeast Michigan (Dearborn Area, Detroit, Eastern Thumb, Grosse Pointe, Lapeer and Upper Thumb, Livingston County, and North Oakland County), each appointing two representatives to the Realcomp Board of Governors. Founded in 1994 as the successor to the original 1983 Realcomp system, the company serves more than 17,000 real estate professionals across 2,600+ offices.

The core product is RCO3® (Realcomp Online), a web-based MLS platform delivering listing add/edit, search, mapping, IDX setup, saved searches, contact management, public records integration, and portal syndication to Realtor.com, Zillow, Homes.com, and Homesnap. The platform is augmented by an integrated technology stack including SentriLock Bluetooth electronic lockboxes (with SentriKey and SentriConnect mobile apps), ShowingTime for appointment scheduling, SkySlope for transaction management and e-signatures, Cloud CMA for comparative market analyses, OneHome consumer portal, INRIX DriveTime for commute analysis, and predictive analytics via domii and Realist. Recent additions include AI-assisted photo management and listing remark generation launched in October 2025.

Realcomp generates revenue primarily through quarterly subscription fees invoiced to REALTORS and brokers for MLS access, data services, and platform usage, with billing handled through the shareholder Boards. Distribution is exclusively channeled through the seven shareholder Boards/Associations, eliminating direct-to-agent sales motion. The company provides hands-on training at its Farmington Hills facility (24 workstations), live webinars, virtual Town Hall meetings, and extended customer support hours. Additional revenue is captured through lockbox shipping/handling charges and ancillary services.
