A rejuvenated Mortgage Partnership Finance program helped its six participating Federal Home Loan Banks more than double the number of home loans funded in 2012, program officials announced this week. Last year, the FHLBanks of Chicago, Boston, Des Moines, New York, Pittsburgh and Topeka purchased $14.33 billion of loans from member banks, a dramatic increase from $6.99 billion in 2011.Introduced in 1997, the MPF provides member institutions a competitive alternative to selling to the GSEs or holding loans in portfolio and retaining all the risk.
