Opendoor leads the iBuying race, but Zillow is catching up

So far this year, Opendoor is winning the iBuying race, as companies scramble to perfect the “instant buyer” business model. But, Zillow is on its heels. Opendoor purchased almost 10,000 homes in the January through July period, around three times the volume of Zillow, according to a report by Mike DelPrete, a real estate tech strategist.
