Most agents that list bank owned properties get started by signing up to complete BPOs (broker price opinions) for banks or REO companies. You can buy lists or REO companies online or you can just find them one at a time with google.
Once you start completing BPOs your job is to find a way to make your name stand out with those companies. I completed about 70 BPOs this year and listed 3 bank owned properties that came directly from those BPOs. The listings were hard work. The BPOs were hard work. But I'm still glad I did it and I'm being told that I will be listing 2 more REO properties in January. I never believe anything until I have it in writing but I think I'm making progress.
