I know what you mean about being difficult from far away. I am currently working in Afghanistan. Although we live in different states, and I am only dealing with REO's right now, I can share what I do to research properties. It may work for you.
My County Assessor has a web page with all active properties in the county. I enter a search under the name field of all banks I know of in my area to locate REO properties. If I find one, I search the previous transactions to see from whom it was foreclosed. I then search their name on the site to see other properties they own. It's a good way to identify possible future foreclosures or a potential motivated seller. I update my list weekly and repeat the process.
My county seems to update the owner information in a timely manner. The properties are almost always changed to the bank's name prior to hitting the MLS in my area. Might be worth your time to see if your county has something similar. Good luck!
