Zillow Housing ValuesI have been using Zillow to track the general trends in my housing property vale, to be able evaluate options with my property. However in May 2011 Zillow stated a value of $559K but in July with a reported change of -1.2% the value dropped to only $426K. So what is the correct value to use? I doubt the property dropped 25% in a month.September 09 2011 - Crownsville00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
