1. Talk to a lender and get pre-approved for a loan
2. Pick an agent and tell them what kind of home you are looking for and they'll find it.
FYI bank owned homes aren't like they used to be. Now there are fewer on the market and the ones that are on the market aren't at the deep discounts they used to be. Now bank owned homes can and often are priced alongside non-bank owned homes. I usually tell me clients that specifically are looking for bank owned homes to focus on finding any available home that fits your needs in your price range.
