Where does Zillow get their estimates and Tax info?I live ina fairly new brick home on a corner lot is West University Place in Houston. Zillow shows the homes here have gone up 0.6% over the last 12 months on average, but somehow thinks mine has gone down about 16% during that same timeframe. How does Zillow come up with that analysis which makes no sense. Also, where does Zillow get their Tax Values. My home shows about $3,200 in taxes, which would be nice, but all my taxes for Harris County, HISD schools, West U taxes, etc was approximately $9,966. If numbers are goig to be put on this site, I wouold think they need to be more accurate.December 24 2008 - West University00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
