Jamie from Trulia here. Our real estate guides are updated on a weekly basis. The average listing prices are currently showing data through July 4th week. In the areas you point out the historical information such as avg. sales price and median sales price are not reported frequently by the county which is why you are not seeing as current information for those numbers. In areas where the county does report the information we update the amounts on a monthly basis. Keep checking back as we are continually working on adding more relevant information to our guides.
