Its a computer program. Blame the tax records and previous sales for these houses for the difference in valuation. The house next door to me was valued in the 400k range as thats what it sold for in 2002. it just sold last August for $750k and the new zillow valuation is just under 700. another house behind me was torn down and rebuilt, twice the size. zillow still has it listed as the older house because the town hasn't updated the tax record--takes them a year around here.<br/>zillow doesn't really know. you can also try the chase home estimator--i like that one better as it says my house is worth 30k more than zillow does.<br/> Thu, 01 Jan 2009 12:16:00 GMT http://www.zillow.com/advice-thread/Accuracy-5624-Ashland-Court-in-91709-is-valued-at-439K-while-5592-Ashland-Court-is-valued-at-481K/183242/ 2009-01-01T12:16:00Z
