Sign into your accountWill Zillow Win the MLS Data Aggregation Wars?
March 08 2017
A new war over data management has broken out among America's largest technology firms, and no clear winner is in sight. To begin, it may be best to level set around what data aggregation is. For brokerage firms or technology companies that leverage MLS data in software, they are pulling MLS data feeds. When you are pulling more than one feed, you are aggregating MLS data.
Brokerage firms and software companies that have hired WAV Group to streamline their data aggregation systems know that we have always focused on the three leading firms that have been aggregating MLS data for years: Homes.com, Real Estate Digital, and WolfNet. From time to time, we do send our RFPs to other firms, but we have never been able to find any vendor who has the breadth of market coverage or the quality of data management systems that compete with those firms.
The thesis for outsourcing data aggregation if you are a broker or a software vendor is simple. Homes.com, Real Estate Digital, and WolfNet already have the data on their servers. Each of them curate more than 98% of the MLS data from more than 600 of the nation's MLSs every day, and in some markets they are updating as much as 96 times per day (about every 15 minutes in large markets). There are easily 4 million updates per day to the data. Rather than duplicating the effort with your data, administrators, brokers, franchises, and software vendors are outsourcing. The price is lower than doing it yourself and, in our experience, these three firms are expert at the job and provide delightful customer service.
