DeustcheBank or any bank will not likely sell directly to you unless you are buying a portfolio of properties in the multimillion dollar range.
You can however buy directly at the courthouse foreclosure auction with ALL CASH and take it as is without inspection or clear title with all surviving liens attached.
Otherwise if you're not willing to take the risk (or don't have ALL CASH) you will have to line up with the many, many "retail" buyers and place your bid after the lender lists the property with a Realtor on the MLS system.
Find a Realtor like Tom Priester to help you because if you try to rely on the listing agent getting you to the property and making your offer on the first day, you may miss out on the very best deals.
All the best,
