how can my house go down 90,000 in one week? Is that the market working. I think not....I have lost credibility in Zillow. Over the course of a couple of years, my house went down 300,000 then back up to 680,000 now back down 90,000 in one day. This certainly is not the market working. I have agents now saying that they put no credibility in Zillow anymore for this reason.May 12 2012 - Merritt Island00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
