how can your zestimate be so wrong? It's off by $250K to $300K on our house.3 houses have closed in the past month on either our street or the next one over in the same development. All 3 went for over asking price yet your estimates continue to be low and not reflective of the marketplace. Please explain that. you have some kind of mathematical formula that may work in some areas, but is way off base around here despite your touting the SF zestimate accuracy.June 02 2011 - West San Jose00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
