I subscribe to ForeclosureRadar. Tell me which property you're looking at and I will send you the information about the scheduled auction, what type of notice was received (Notice of Default, Notice of Trustee Sale), who the lenders are.
If you aren;t working with a realtor, it will help a lot to engage one who can serve you in this regard. Most foreclosed properties will be listed via a realtor who will then post the information on the MLS. All of us can pull up specific properties for sale as regular sales, foreclosures or short sales.
