Why has Zestimate started using tax valuation for property values in DE?This is completely stupid as the tax values are 1/4 the value of the home in this area. If you look at houses in 19711, 19707, 19808, etc., they all drop 75% over night to a rediculous value that no house sells for even if it burned down.June 03 2010 - New Castle00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
