Zillow Advice: Home Ownership - Zestimate is TOO LOW and will not update!!! http://www.zillow.com/advice-thread/Zestimate-is-TOO-LOW-and-will-not-update/437694/ Zillow Advice | Zillow Real Estate Hi there,It looks like your ... http://www.zillow.com/advice-thread/Zestimate-is-TOO-LOW-and-will-not-update/437694/ Hi there,<br/>It looks like your original sq ft was the same as your neighbors and the home facts were just edited within the last few days to show the finished basement. This change will eventually be calculated, but not instantly. As Pasadenan stated, the zestimates are calculated 3x/week. Home fact changes are calculated gradually over several weeks. <br/><br/>I noticed your tax assessment is slightly lower than your neighbors. <br/><br/>You can keep an eye on it and check for changes over the next few weeks.
