I live in STL & noticed recently the Zestimate for homes my street have gone up a lot. Why?The Zestimate on my house is $345K. Just a couple of months ago it was under $290K. I realize homes selling in my area can affect the value of my house but it wouldn't change the historical value would it? Why the sudden increase in value (not that I'm complaining). BTW, I love your site!!!Thank email@example.comJuly 05 2011 - Oakville00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
