Newbie here-how do you locate foreclosures

[N/A N/A]

I went to my County Clerks office and they told me, after talking to three people, that all auction houses are listed on a board. When I got there they were in fact on a poster board, along with every other person or business that was being sued. They told me they do not list it online. How do you guys find foreclosures? There must be a better way.

Thanks,
Dave
