Zestimate values hacked, look at Zestimate chart!My home at 440 66th St, Oakland, CA 94609 was purchased in June 2007 for $875k and the Zestimate value, after the algorythm change, rose in the next year to $5million! This is wholly incorrect and the fluxuations now (My Zestimate @ $586k) do not show up due to this hack job! Can you correct this?May 02 2012 - Oakland00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
