REOs - Getting around pre-approval requirements

[Carlos Flores]

Just about every REO around here that I want to submit an offer on requires the buyer be pre-approved or pre-qualified by the bank's specific lender if the offer is not cash. I don't want to get pre-approved by countless lenders just to submit offers. Here are some examples directly from MLS: Buyer MUST be pre-qualified through Prospect Mortgage; BofA Prequalification required on all offers; Merrill Lynch Prequalification required on all offers. As you can see, they are not just requiring any pre-qual. How can I get around this issue if I am using a private lender or a hard money lender?
