Can I trust Zillow estimates?

Zillow is a popular Internet marketer that provides computerized estimates that claim to calculate the value of each and every property in the United States. Zillow tries to reach this goal this feat by using a complicated program which crossreferences factors which alter property values, but here's a typical story I have heard from home sellers in Northern Virginia:

Is Zillow accurate? — Many consumers have serious doubts about the accuracy of Zillow home value estimates.

Our home was recently appraised for 650K. Zillow estimates the value at 521K. The estimate makes us one of the lowest priced homes in the subdivision. We have all upgrades in our home and it is the largest of the homes that were originally built in this subdivision. It was appraised at 750K before 2009. Our home has a basement. Neighbors do not have basement on one side and you appraised higher. Really? -- James E. - Fort Hunt

If you search the Internet for the phrase "Can I trust Zillow?" or "Can I trust Z-Estimates" you'll find many posts by angry homeowners and skeptical real estate shoppers who have discovered the hard way just out inaccurate Zillow's pricing can be. Many people in Fairfax Manor report that Zillow's estimates have a margin of error of approximately 20%. Even if we assume the margin of error is only 10%, in Northern Virginia that means a "z-estimate" is only within $50,000 of the actual market value. If the margin of error is an astounding 5% that means that a z-estimate is only within $25,000 of the asking price.

Yet Zillow still remains popular with some buyers and sellers. Property owners and home shoppers should understand that there is not a single neighborhood in Fairfax Manor where either a bank or tax collector uses Zillow for tax assessment or appraisals. Our expert advice is to take estimates from any website with a grain of salt. Putting too much reliance into a computer logarithm can cause a lot of disappointment.
