Accuracy of Zillow estimates?It is utterly amazing what you folks do with the house values. My home according to you surprisingly increased most of 2009 and part of 2010 surpassing a neighbor's home which has a bigger lot and is a larger home. Now, for no apparent reason other than correcting erronous estimates, the value according to you has dropped about 20% and the neighbor's has gone up. There really is very little apparent rationale on how you do these estimates and by creating this type of distortion you minimize the value of using any of your numbers in asking for a new real estate tax appraisal. What is the explanantion without a lot of excuses? This is a free service and appears to be not that accurate or realistic.JimMarch 11 2011 - Long Grove00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
