You have to wait until the property is assigned to Deutsche's asset management, aka REO, company. Once it is assigned the AM will begin the process of market and repair cost evaluation. Once they have a good idea of the property's value they will assign it to a listing agent and advertise it for sale. At that time you/your agent can submit your bid to the listing agent.
One of the main AM's for Deutsche is Altisource aka OCWEN Loan Servicing, LLC.
