Home value is understated because of "good" original price and winning a tax appeal ...I bought my house for a "good" price THIRTEEN years ago, and this seems to continue to depress the Zestimate. Also, I was one of a few in the neighborhood who knew that tax valuation could be reduced about five years ago by a certain percentage "just for the asking", and I did it. I suspect purchase price and tax value are the two most weighty factors in the Zestimate! AFTER SO MUCH TIME HAS PASSED, why is my house STILL estimated at the lowest value per square foot among 150+ houses in the neighborhood? In other words, .... just because I was "clever" in two ways, does this depress my Zestimate FOREVER?January 05 2014 - Six Forks00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
