Zillow Advice: Zestimates - Comps 2 doors away 10K diff? http://www.zillow.com/advice-thread/Comps-2-doors-away-10K-diff/494414/ Zillow Advice | Zillow Real Estate I see that Zillow (Rachel ... http://www.zillow.com/advice-thread/Comps-2-doors-away-10K-diff/494414/ I see that Zillow (Rachel Rosen) responds about such differences ( http://www.zillow.com/advice-thread/Zestimates-Price-History-Tax-History/415515/ ) in zestimates as sales history + past tax assessment ... if such were the case then Zillow's zestimate is completely then Zillow has really got mine wrong. &nbsp;My reply to Zillow and Ms. Rosen's zestimate explanation follows: &nbsp;<br/><br/>"This eplanation is factually incorrect on its face: &nbsp;BOTH the tax history and sales history on the home I bought last June in Vacaville is significantly higher than a "comparable" property 2 doors away yet Zillow has my property (with an in ground pool the other lacks, an additional bedroom which the other lacks and more recent custom upgrades) 10,000.00 lower than my neighbor. My neighbor's property, though nice, NEVER sold for more than 235K nor assessed for more than 227k whereas my home at 912 Summerbreeze CT sold for 349,900.00 in '04 and was taxed at an assessed rate in '07 of 371,317.00 and never assessed below 300k until the collapse began in '09. &nbsp;<br/><br/>So this formula as you explain it is patently and factually untrue by Solano County public records. &nbsp;Even at the current post collapse rates my discounted accessed property tax is 10K higher than the neighbor you zestimate 10K more than my property. &nbsp;I was warned about Zillow's inaccuracies because I used to compliment Zillow when I was house hunting. &nbsp;Now seeing how wrong your estimates AND your explanations for them are I will make sure I tell every home owner my experience."<br/><br/><div>Oddly enough Zillow publishes the Solano County tax assessors records for both my "nearly comp" neighbor's sales history + tax assessment history as well as mine as Ms. Rosen for Zillow explains. &nbsp;However, if her explanation of sales history + tax assessment history were factual then my property would follow those public Solano County facts. Well, clearly they don't. &nbsp;Instead, Zillow "zestimates" &nbsp;AGAINST both property sales price history since '99 as well as property value tax assessment history. &nbsp;Zestimate as a starting point or not Zillow damages property owner/sellers by not following their own formula (as Ms. Rosen explains it). &nbsp;I've checked with building permits here in Vacaville and there have been no additions to my neighbor's property and it still assesses lower than mine with the County Property Tax Assessor. &nbsp;If Zillow followed the supposed formula of sales history + assessment history without frilling it up with a secret&nbsp;algorithm maybe they would have far fewer complaints about their zestimates because in spite of Ms Rosen's claim (for Zillow) in my case past sales history and past tax assessment were ignored resulting in a lower Zestimate while they were also ignored in my neighbor's case (who has a nice house but lacks a pool and a 3rd bedroom like I have - both sets of facts appear on the tax assessors PUBLIC records) receiving a zestimate that goes against the sales history = tax&nbsp;history formula Ms. Rosen says Zillow partly relies on. &nbsp;I refuse to put an owner estimate on my property as Zillow says I can. Why should I correct their error? When I sale I will hire an&nbsp;appraiser ... in the meantime I find it very off-putting that Zillow has so many complaints about Zestimates yet sticks with them and doesn't even follow their own explained sales history + tax history explanation.</div> Thu, 30 May 2013 15:21:00 GMT http://www.zillow.com/advice-thread/Comps-2-doors-away-10K-diff/494414/ 2013-05-30T15:21:00Z
