About Mid America Regional Info Systems
Mid America Regional Info Systems (MARIS) has carried the St. Louis region's listings since 1995 and now serves more than 15,000 members through 14 REALTOR associations. Mid America Regional Info Systems IDX puts that inventory on an agent's own website, from Central West End condos to Franklin County acreage.
MARIS in brief:
- Established in 1995 as the regional MLS for greater St. Louis
- Serves more than 15,000 members across 14 member associations
- Covers more than 50 counties in eastern Missouri and southwest Illinois
- St. Louis REALTORS and the St. Charles County association are among its boards
A two-state metro needs a two-state database, and MARIS is exactly that: one feed spanning the river your buyers cross daily.
