Whether or not the data collected in this article is questionable, there's a pretty easy way to evaluate the price of your home: re-finance / hire an appraiser. If you believe your home to be worth more, wouldn't it be worth the $200 or so to increase the value of your home by thousands by having an accurate market research from a qualified appraiser? I got mine as part of my refinance package, so I have a very accurate estimate of what my home is worth, comped out against other homes in my area that sold recently at a similar location/sq ft/etc. Not sure why you feel the need to use questionable data points like Zillow in the first place.
