Hopefully most people are aware that the estimates on Zillow and therefore Trulia are pretty much worthless. We purchased a home in a Los Angeles market that has done nothing but skyrocket in the past 4 years and yet two years ago, Zillow dropped the value of our property by roughly 200K over their own previous estimate. An email to them resulted in a generic form letter telling me to how they arrive at their estimate and stating in bold italics that they do not edit them based on homeowner information. In other words, they did not look at what they have done to my particular property value, nor do they care.
