In my experience selling several houses over the past few years, Redfin is much more accurate than Zillow. Zillow for the year or so prior to each sale, valued the houses as 1-2 hundred thousand lower than Redfin. Redfin was very close to the actual sale price. What Zillow does is, the day the house is placed on the market, its Zestimate will jump a few hundred thousand dollars to where Redfin has always been. Then when the house sells, Zillow is accurate. But for some reason, until the house is actually put on the market, it gives a very low ball estimate. Redfin is much more accurate in my experience.
