True values, poor formulasWhile many consider a valuable service, the methodology of applying a general formula to specific properties allows for completely false values. If you say for example that values in town X decreased 1.5% this month and then just subtract 1.5% from every home in that town (zip) is inaccurate. Example: if you start a starting value on a property of $100,000 and then Devalue it by 1.5% a month, with no other positive factors, this will eventually give you a value of ZERO. At what point does the zillow math account for the fact that it should never reach "zero"? Realtors/lenders use zillow as an estimate,,,but come on, be real. Waterfront homes loose 1.5% a month for the last 3 yrs?October 14 2011 - Irmo00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
