Finding foreclosures can be done by going to your local recorders office. Some offices are even available online. You will want to do research for NOD's and/or Lis Pendens
By foreclosures I assume you are meaning REO properties. Realtors are a great way to find these properties.
Assigning properties that are in foreclosure can be difficult to do as the banks generally do not like assignments of contract. In another forum I ran through an option of how to use an LLC to "assign" a property.
Realtors can help you put the paperwork together.
