If you catch these at the pre-foreclosure stage as slow pays or initially in default all the better as the bank has less in collection expense.You can still work out a discount but even buying at the payoff it can be profitable depending on the property value.You can practically force a lender to sell as it can fully indemnify them as a full payoff as demanded, continuing with a foreclosure becomes a rather vengeful act by the bank to punish a borrower, they don't want to go there.
