These two sites also filter out the short sales that are under contract and awaiting final bank approval (AWC).
Web sites like these are build for marketing. So it's up to the company, the broker or the agent to feed these sites. The only updated information tool is the MLS.
I have a listing in Maricopa that I listed on Saturday, had multiple offers on Sunday and our company system did not post to Trulia until Monday when it was already being sold.
I live in Maricopa, Glennwilde and I am very familiar with this area.
