Another challenge has been to ensure the quality of Zillowâ€™s Real Estate data. Most of the data comes from county courthouses, and accuracy is very high. More than 62 percent of house prices are within 10 percent of their â€œZestimate,â€? said Rascoff.
I’ve often wondered if Zillow isn’t the Alexa of real estate pricing: Interesting, but ultimately not business-decision worthy. Today, however, I’m ready to believe IT IS VERY ACCURATE. I just checked the estimate on our house, which we’re still desperately trying to sell, and Zillow says our value has increased $15,000 in the past 30 days! Eeee-Haw!
