In this "By the Numbers" statistic post, we take a look at some statistics and facts about Zillow, one of the world's largest real estate networks. It seems that just about every start-up these days is focused on disrupting some established industry or service. Some succeed and many, many fail to show the traditionalists a new, better, digital way\u00a0and change their world. One digital company, Zillow has definitely succeeded at disrupting their industry. Zillow challenged the real estate industry by creating a platform that used digital data to redefine a number of conventions like real estate discovery, property values, mortgages, etc. Zillow is now a go to site for real estate buyers, agents and even industry analysts. Now, with their purchase of rival Trulia, Zillow seems poised to continue this momentum through 2019 and beyond. Here are a few of the more interesting Zillow statistics I was able to dig up recently. As always, I will be updating this post as I find new and updated stats, so be sure to check back occasionally or sign up for email notifications below.
