Fannie Maes plan to unload, potentially, billions of dollars of non-performing residential loans has been delayed and may be killed, according to industry officials whove been tracking the project. Its going nowhere, but its not like theres a requirement for them to say so publicly, said one advisor who is a vendor to Fannie. The GSE, to date, has declined to discuss the issue along with its regulator, the Federal Housing Finance Agency. Fannie has been working on an NPL sale for close to a year, and even hired an investment banker, Milestone Advisors LLC, to guide it through the auction process. Initially, it had hoped to offer a package of $250 million of delinquent home mortgages for sale to the highest bidder.
