I would not trust Trulia, Zillow, or any financial institution who uses them for any transaction. Our home is 2,604 sq ft, confirmed by two appraisals, with 4 baths and 5 bedrooms. Both Trulia and Zillow have it listed as 2,258 sq ft with 3 baths and 4 bedrooms. I have entered the "owners data" but it never changes the estimate of value. Really just a joke and can't be taken as a serious measure of the value of your home. Hire an appraiser and don't let any bank use this site or others to determine the value of your home.
