Just saw this on NBC Nightly News about Zillow getting sued for showing home values lower than what they should be.  If you have a problem with Zillow you should consider joining the class-action lawsuit.

We've said this countless times and here it is once more:  Zillow is a farce and the single most misleading real estate website in the World.  

No website can possibly know what your home is worth, so if you are naive enough to believe everything you see on the Internet, we feel sorry for you.  Zillow's excuse is they get their data from County records.  Know the last time the County records were accurate?  N.E.V.E.R.
