Finding non listed REO properties

[John Shortridge]

Hi Everyone, I'm new to this forum so I'm not sure if there is already a thread.

I have located a few bank owned properties using my county's property assessor's website. I'm pretty sure they are foreclosed because they are vacant and with notes on the windows. They aren't listed however, and a few I have noticed for several months. I'm wondering if anyone has had any experience in tracking down an agent for these properties. Does a bank just sit on some of these indefinitely? Or will they eventually list them all?

Thanks!
