WHY are Zillow's TAX & INSURANCE Estimates SO WRONG???I regularly track 2 CA properties. Zillow's Monthly Estimates of both RE Taxes and Insurance are grossly wrong! Why?RE TAXES: Zillow's monthly estimates DO NOT REFLECT either CURRENT RE Taxes, NOR the 1% of Valuation (per CA's Prop 13) a buyer would pay!!!!!"Homeowners' Insurance" Zillow estimates $78/mo for BOTH a $1.5mm AND a $7.7MM home! That's IMPOSSIBLE! Plus "Homeowners" is incorrect and useless. To wit: THREE insurance policies protect our home::: Fire & Casualty (protects the bldg, most expensive!); Homeowners (protects belongings, clothes, furniture...); and Excess Liability. Again, it's IMPOSSIBLE $1.6mm & $7.7mm properties pay the SAME insurance!!! Zillow's sloppy errors & ignorance is doing many a disservice. You corrected the RE Tax issue once, then slid back.Why so sloppy, WRONG?May 16 2013 - San Francisco00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
