Realty Trac listings on Trulia are not necessarily actually for sale (and I could not find an MLS listing for this address). Realty Trac wants to sell you a subscription $(49.95?month) to their service which provides information on NOD's and homes in other stages of what might some day be a listing for sale or even a sheriff's sale.
NOD's (Notice Of Default) are nothing more than a notice from the lender to the owner that they are 90 or more days behind on the payments, which gives the lender the right to START foreclosure proceedings. If the owner brings the mortgage payments current, or makes other arrangements with the lender, the home never goes up for sale, even though it looked like it was from the Realty Trac posting.
That might explain why you could see a RealtyTrac listing on a home that's not actually for sale. for more about Realty Trac's "listings" read my blog post at http://www.trulia.com/blog/dave_sutton_windermere_walnut_cre
