There are a number of web sites offering this information. Some of the sites are fee based. I am not sure whats available in your area but just google the question and I am sure you will find the information.
If you are interested in investing in REO's, you would need to have a Realtor in your corner.
Realtors, acting as a Buyer's Agent are free to you,
Their council and research are, likewise, free.
Probably the best deal of your life!
Good luck and may God bless
