How does Zillow estimate home values?My home information in Denver public property records is out of date. It displays as a 2 BR 2 BA home that hasn't been updated. However I updated both kitchens, both baths, built a garage, added glass block windows, planted 5 trees, etc. etc. Plus I have egress windows in the 3 major rooms in the basement: both BRs and the FR. How can I get those improvements to show up in the Zillow Zestimate?June 22 2011 - Highland11YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
