Does Zestimate use square footage ? Zillow had the incorrect sq ft (10% low). Does this affect ZesZillow had the sq ft incorrect - low by about 8%. I have corrected this, but the estimate is way low - Zestimate says the house is worth about 15% lass per sq foot than other homes in the area, but they are all similar tract homes - this makes no sense. I wonder if Zestimate is still using the sq ft from public records, rather than the one that I changed by "owning" the home. These are 10 year old homes without significant upgrades, etc.July 15 2009 - Morgan Hill00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
