Why we use Zillow:

Zillow Research Data provides frequent housing data (monthly, with a delay of only a few weeks) for very specific geographic locations (neighborhoods, zipcodes, cities, counties, MSAs, States, and the U.S.).  For particular homes, Zillow may not be entirely accurate, but after aggregating over zipcodes, cities, or the entire country, the Zillow Home Price Index (ZHVI) is accurate and adjusts for many of the problems that occur in other home price data like the California Association of Realtors (CAR) data and the Case Shiller Home Price Index.  To read more about Zillow's housing data, see the following two links:
