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 research the web for the phrase "Can I trust Zillow?" or "Can I trust Z-Estimates" you'll find many complaints by upset property owners and leery property shoppers who have discovered the hard way just out inaccurate Zillow's pricing can be. Many people in Crystal City report that Zillow's estimates have a margin of error of around 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 sales value. If the margin of error is an unlikley 5% that means that a z-estimate is only within $25,000 of the asking price.

Yet Zillow (for now) remains popular with some real estate shoppers. Home sellers and property buyers should know that there is not a single community in Crystal City where either a bank or tax collector uses Zillow for tax assessment or appraisals. Our professional advice is to take estimates from any website at arm’s length. Putting too much trust into a computer can cause a lot of confusion.
