You know, we often advise people that Zillow, Trulia, Homes.com and others are NOT an accurate reflection of what the real values of properties are. And, I thank you for making that statement for us!!! Lots of people don't believe us when we tell them how erroneous the information is, they think we're just trying to make them come to us for the info. While that's partially true, it's also because we want people to have accurate and relevant information!!!
Not sure how you can change your Trulia info, but if it's based on what's in the trulia data base, not sure that can be helped.
