When Trulia shows a home as a foreclosure it means that the bank has eventually foreclosed on the home and is now the owner. Before offering it for sale (and it may or may not get listed for sale - some homes are being sold in "packages") the banks will clear up any liens and possibly arrange for it to be brought into acceptable condition. This could take many weeks.
If you are interested in knowing about bank owned properties that are now offered for sale, let me know and I will be happy to let you have details.
