Which REALTOR® associations are part of RMLS Alliance?
RMLS Alliance serves members of the Capital Area Association of REALTORS®, Egyptian Board of REALTORS®, Peoria Area Association of REALTORS®, and Quad City Realtor Association MLS.
Is RMLS Alliance the same as RMLS in Portland, Oregon?
No. RMLS Alliance is an unrelated regional MLS serving Illinois and Iowa; it shares no data, ownership, or coverage area with the Regional Multiple Listing Service in Portland, Oregon.
RMLS Alliance covers 61 counties across Illinois and Iowa – roughly 30,000 square miles serving more than 2 million consumers. Coverage runs from Cairo, Carbondale, and Mt. Vernon in Southern Illinois, up through Springfield and the Capital Area, into Peoria, and out to Galesburg and the Quad Cities on both the Illinois and Iowa sides of the river.
