What defines power? Certainly not popularity, Stefan Swanepoel opines in his 2017 list of residential real estate industry heavyweights, released today with Zillow Group CEO Spencer Rascoff winning the top spot.

The Swanepoel Power 200 (SP200) annually ranks the 200 most powerful people in real estate along with a series of influencer subsets including corporate executives, power brokers, technology executives, association/MLS executives and women leaders.

In addition to the main power list, the SP200, generated by the Swanepoel T3 Group, recognizes additional movers and shakers in four bonus categories: Trendsetters, Social Influencers and Outside Powers. Emerging Leaders, honoring leaders under 40, was a new SP200 spotlight this year.
