Zillow Data Accuracy Under Fire Again
Using Zillow to search for homes for sale? Think again.
Currently, Zillow.com has fewer listings than Realtor.com in 40 out of 51 cities. The discrepancy is often quite substantial: in 23 of the 51 cities, Zillow.com has more than 20 percent fewer listings, and in a couple of cities Zillow.com is behind by more than 40 percent!
In a handful of cities, notably New York, Phoenix, Detroit, Portland (OR), Buffalo and its hometown Seattle, Zillow.com provides more listings than Realtor.com. While this may indicate the absence of some listings from Realtor.com, it may also reflect data quality issues in Zillow’s database, such as incorrect listing details, or duplicate or expired listings.
So what do we recommend? In Seattle, Redfin is our fave (disclosure: I’m a shareholder) but you’d be well served by any MLS-powered site such as Windermere, John L Scott or Estately.
