First off I have to mention that Trulia and Zillow ARE NOT usable measures of the value of a property because they use out of date information to value a home. It's fun to play with, but not a substitute for a professional appraisal or even a Comparative Market Analysis or Broker Price Opinion performed by an experienced professional Realtor.
Secondly, by statute "the data-gathering period used to estimate the value of property for 2013 value shall be the 24-month period running from July 2010 through June 30, 2012. Only properties having sold within this 24-month time frame may be used as comparables when estimating a market value!" So this value does not represent the CURRENT market value, but the approximate value during the statutory time period.

I hope you find this information of use
