Most buyers think they’re seeing “everything” on Zillow. They aren’t. What just happened in Chicago is proof.
Midwest Real Estate Data (MRED), the MLS serving the greater Chicago area, recently cut off Zillow and Trulia’s access to its listing feed during a licensing dispute. Overnight, tens of thousands of active listings disappeared from those platforms.
Buyers searching Zillow had no idea those homes existed.
That should concern anyone relying exclusively on third-party real estate sites.
Zillow is not the MLS.
It’s a licensed advertising platform that depends on agreements with MLS systems and brokerages to access inventory. Those agreements can change. They can expire. They can be revoked.
As private listing networks expand and MLS policies continue evolving nationwide, data fragmentation is becoming a very real issue in real estate.
This is not just a Chicago story: It could happen in any market - including here in Massachusetts.
There are two major MLS systems across my coverage area. I’ve seen buyers and even industry professionals unintentionally operate with incomplete information because they only had visibility into one data source.
That matters.
Incomplete data affects pricing strategy, market analysis, competition visibility, days on market interpretation, and ultimately the decisions buyers and sellers make.
Ohr team built websites with direct access to both MLS systems in my market. Clients and the curious alike can see the most complete and accurate picture possible, whether they’re searching for a home or evaluating their own property against active inventory.
The bigger question is this:
How much trust are consumers placing in platforms that don’t actually own the data they display?
And if listings disappeared tomorrow, would you even know what you were missing?
