The ZPP’s common objective is to provide and display precise, curated, and near-real-time listing information that serves both agents and consumers.Īs part of ZPP, a listing management and reporting platform that puts increased control in the hands of MLS members and brokers who send a direct feed to Zillow, MLSs can take advantage of the new Zillow Data Dashboard. Many MLSs are part of the Zillow Partnership Platform (ZPP), which was established through a direct relationship between Zillow and the listing information originators (brokers) or keepers (MLSs).

Some confidential information will appear in MLS listings, but not in Zillow listings, such as the contact information of a homeowner, the access code to a gated community, showing directions, or the amount of the agent’s commission. MLS listings, however, are distributed to thousands of public websites that can be accessed by anyone, including Zillow. Does Zillow Use MLS Data?Īn MLS can only be accessed by licensed real estate agents, although some allow appraisers and assistants or office managers to participate, even if they are unlicensed. Those agreements really restrict what they can do with the listings data. To get access to that data, Trulia and Zillow need to negotiate data sharing/syndication agreements with MLSs. Redfin has great freedom to use listing data from its membership in the Multiple Listing Service (MLS) of Realtors, as it is a brokerage. Redfin is a real estate brokerage, while Trulia and Zillow are “third-party data aggregators.” All three start with county data in areas where available (a few states, especially Texas, do not consider public information on property sales). How are Trulia, Redfin, and Zillow different? Public record data (i.e., price history and tax record) are not included on the listing-generated property pages thus, these property pages usually host fewer home data. This can be achieved by applications such as SimplyRets, iHomeFinder, Spark APIs that help normalize MLS data flows, as fields in the MLS database of each area need to match up to the Zillow database to display the data in Zillow’s format.įurthermore, listing-generated property pages can contain information related to previous listing activities.
When real estate brokers opt into “listing syndication” to the Zillow Group, Zillow is sent MLS data information in a “feed” directly from MLS.

As we receive it from data providers, they periodically update this information. The parcel data from Zillow, detailing the lot on which a house sits, comes from different public sources, such as the county. Public information obtained from county documents is the data Zillow offers.
It receives information from the municipal office responsible for recording real estate transactions in your area concerning property sales. Google Places,, Onboard Informatics, and many others. Zillow receives information from many external parties, many of which are not disclosed because this is their “magic ingredient.” Cities in the US provide information on open data portals that Zillow can use for price history, trends, demographics, comps, etc. The bulk of data today comes from local MLS, county records, user-entered data and pictures, and agents manually enter data. Zillow had to create individual relationships with Multiple Listing Services (MLS) across the country when the list hub decided not to renew the agreement.įortunately, Zillow had seen this coming and worked on it for a while. They have always filled in the local public records with data. A short time ago, Zillow had an agreement with the list hub until which provided them with the bulk of their listings data across the country. Zillow gets its information from a variety of sources.
