MARIS Outperforms Its Associations in Stability, Solidifying Its Role in the St. Louis Real Estate Market
In a shifting real estate landscape marked by declining membership in many markets, MARIS (Mid-America Regional Information Systems) stands out as a model of stability and strength. Headquartered in St. Louis, MARIS is the MLS for the St. Louis metro area, and surrounding counties, serving 10 local associations across Missouri and Illinois. As of year-end 2024, MARIS recorded 15,014 subscribers—a decline of just 2.1% from the previous year. Compared to the drops seen in many of the associations it serves, this is a noteworthy achievement.
To put it in perspective, the St. Louis REALTORS® Association, the largest local association within the MARIS network—saw a membership decline of 3.6%, nearly twice the percentage decrease experienced by MARIS. Other member associations like St. Charles County Association of Realtors (-3.8%) and Greater Springfield Board of Realtors (-1.3%) also experienced steeper or similar drops. In contrast, MARIS’s relatively modest decline suggests both stronger subscriber retention and continued relevance in supporting agents’ business needs.
This performance places MARIS as the #2 ranked MLS in the West North Central region, trailing only NorthstarMLS (based in Minnesota), which posted a subscriber count of 21,285 but experienced a higher 3.7% year-over-year decline. Among regional MLSs, MARIS demonstrates one of the strongest ratios of subscriber retention—even outperforming larger peers in terms of year-over-year resilience.
One reason for this strength may be MARIS’s broad service footprint and commitment to regional cooperation. As a regional MLS, MARIS provides integrated services and robust tools across association boundaries, creating consistency in data and resources for agents throughout the St. Louis metro area. This wide-reaching infrastructure allows it to cushion against localized membership dips and continue delivering value across a larger agent base.
For real estate professionals in St. Louis, this matters. A strong MLS like MARIS ensures access to accurate listing data, smooth cooperation between brokers, and the ability to stay competitive in a fast-changing market. While some local associations saw their numbers shrink more significantly, MARIS’s role as the digital backbone of the region’s real estate transactions keeps it central to agents’ success.
In an environment where technology, efficiency, and accuracy are more important than ever, MARIS proves that a well-run MLS can provide resilience even when local associations face headwinds. For agents, brokers, buyers, and sellers in the St. Louis area, that’s good news—and a reason to feel confident about the systems supporting the market in 2025.
In the interest of full disclosure, I should note that I currently serve as Vice Chair of the Board of Directors for MARIS. While this article was not written in that capacity, I do have a bias in favor of MARIS.
