How Accurate is a Zestimate?

Shamrock Estates - Gilbert Real EstateAccording to an article in the LA Times (link to article here), Zestimates can be extremely inaccurate. As a Realtor, these Zestimates can really kill a deal and bring a lot of unnessary stress to all involved. Here’s a breakdown on how this happens from the article written by Ken Harney. {Are Zestimates accurate? And if they’re off the mark, how far off? Zillow CEO Spencer Rascoff answered that they’re “a good starting point” but that nationwide Zestimates have a “median error rate” of about 8%. Whoa. That sounds high. On a $500,000 house, that would be a $40,000 disparity — a lot of money on the table — and could create problems. But here’s something Rascoff was not asked about: Localized median error rates on Zestimates sometimes far exceed the national median, which raises the odds that sellers and buyers will have conflicts over pricing. Though it’s not prominently featured on the website, at the bottom of Zillow’s home page in small type is the word “Zestimates.” This section provides helpful background information along with valuation error rates by state and county — some of which are stunners. For example, in New York County — Manhattan — the median valuation error rate is 19.9%. In Brooklyn, it’s 12.9%. In Somerset County, Md., the rate is an astounding 42%. In some rural counties in California, error rates range as high as 26%. In San Francisco it’s 11.6%. With a median home value of $1,000,800 in San Francisco, according to Zillow estimates as of December, a median error rate at this level translates into a price disparity of $116,093. Some real estate agents have done their own studies of accuracy levels of Zillow in their local markets. In Carlsbad, Calif., Jeff Dowler, an agent with Solutions Real Estate, did a similar analysis on sales in two ZIP Codes. He found that Zestimates came in below the selling price 70% of the time, with disparities ranging as high as $70,000. In 25% of the sales, Zestimates were higher than the contract price. In 95% of the cases, he said, “Zestimates were wrong. That does not inspire a lot of confidence, at least not for me.” In a second ZIP Code, Dowler found that 100% of Zestimates were inaccurate and that disparities were as large as $190,000.}   It seems that you really are better off relying on the professional REALTORS for a realistic home value analysis.
