California MLS Data Sharing Update

by Victor Lund on May 9, 2014

California Regional MLS and MLS Listings have reached an agreement to share MLS listing data. This is an important signal of MLS strategy in California for a number of reasons. These MLSs are planning to share data by sending data to each other for display in each other’s system and use by each other’s subscribers without the need to belong to both MLSs. Previously, CRMLS only pursued data sharing through CARETS™, a hub and spoke data share product developed by MRIS. Through this new sharing agreement with MLS Listings, CRMLS now has adopted three initiatives to create a statewide MLS system in California. The first is through mergers. The second is through their hybrid solution at allows any California REALTOR® Association to offer CRMLS service along with their current service. This hybrid solution is active between CCRMLS on the California central coast and CRMLS. The third is reciprocal data sharing where data is synchronized between cooperating MLSs as represented here with this agreement with MLS Listings. Why data share? The press release says that the data share is to promote “boundary free access to real estate data” when it refers to the largest data share in the nation – CARETS™. In areas where many MLSs share boundaries with lots of listings, a condition called Overlapping Market Disorder (OMD) exists. I am not sure if the term OMD first emanated from David Charron of MRIS – but that is the way I remember it. Where there is OMD, listings are entered into multiple systems and there are multiple dues. This drives up expenses for everyone and creates duplicate efforts to enter and manage data – not to mention how it throws off market share reports, market sales reports, property search on IDX powered websites and many other data driven business tools. Data sharing cures many of these issues. This was the reason CARETS was created in Los Angeles, but CRMLS is departing that program and effectively doing the same type of data sharing, but on an individual MLS by MLS basis. Why not support CARETS? CRMLS has notified the CARETS organization of Los Angeles area MLSs that it intends to withdraw from CARETS but enter into reciprocal data sharing agreements with any MLS in California that wants to share. The data share between these two entities is an extension of that strategy. Today, it is believed that direct data sharing is […]
