Maine Listings

What Maine Listings does

Maine Listings, doing business as Maine Real Estate Information System, Inc. (MREIS), is a for-profit corporation that operates the unified statewide Multiple Listing Service (MLS) for the state of Maine. Founded in 1994 following a 1993 consolidation of 13 separate regional MLSs (completed when the Downeast MLS joined in 2010), the company is wholly owned by the Maine Association of REALTORS (MAR) and is headquartered at 92 Darling Avenue, South Portland, Maine. It serves as the primary listing distribution and data infrastructure for the Maine real estate profession, providing a single statewide platform that replaced a previously fragmented system where agents historically had to join multiple regional MLSs.

The core product is the Maine Listings MLS Platform, which aggregates active residential, multi-family, land, and commercial sale listings (11,379 active listings) and supports add-on modules for rentals, personal property auctions, and commercial leases, as well as directories of 6,435 member agents, 225 appraisers, and 982 member offices. The platform is built on technology provided by Solid Earth, a TRIBUS Group Company, and includes interactive market insights powered by Domus Analytics. Revenue is generated through recurring MLS membership fees structured on an office-based pricing model originally adopted at founding, with member brokerages paying for access on behalf of their affiliated agents. No external funding, M&A, or capital-raising activity is associated with the entity.
