MiRealSource’s Web-based software offered to REALTOR® members is used for collecting, searching, and distributing listings for brokers and agents. The MiRealSource MLS system was rated No. 1 in both the 2013 and 2014 national surveys. MiRealSource is a member of the Great Lakes Repository (GLR), which allows REALTORS® of participating Multiple Listing Services to share data and work together throughout the state. The GLR benefits sellers by giving their home more exposure to other agents, while also providing more inventory for buyers.




Is your MLS or Association interested in joining this innovative movement for the real estate industry? Please contact us and we will be happy to get you started! 

The Great Lakes Repository is Still Going Strong


We are at the point now where everyone realizes the great benefits of the Great Lakes Repository (GLR) and supports its’ overall goal. Data sharing has been a goal of MLS’s and REALTORS® for many years, and the GLR has made terrific headway in creating a statewide database for data sharing.  The GLR is a single database for multiple MLS’s to share MLS data with other participating MLS’s in each of the individual MLSs home systems.
