Spencer Rascoff: 'The days of the part-time agent are over'

Zillow Group CEO says company is focused on 'creating these super agents and growing their business'

Zillow Group’s strategy of capturing the business (and advertising dollars) of top-producing agents seems to be paying off — in a big way. In the company’s fourth-quarter and overall 2015 earnings call, it revealed that its average monthly revenue per advertiser (ARPA) was $438. That’s a big jump from $339 in 2014 — a spike of 29 percent.
