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 Google the Internet for the phrase "Can I trust Zillow?" or "Can I trust Z-Estimates" you'll discover countless posts by upset property owners and skeptical real estate buyers who have discovered the hard way just out inaccurate Zillow's pricing can be. Many people in Mason Neck report that Zillow's estimates have a margin of error of about 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 buyers and sellers. Property owners and property buyers should understand that there is not a single neighborhood in Mason Neck 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 website can cause a great deal of irration.
