Housing bounced back in 2012, as did Fannie Mae. The government-controlled mortgage giant posted record profits of $17.2 billion and made it through the year — the first since 2008 — without new government bailout funds. That’s because housing prices jumped 8% last year while delinquencies continued to fall. It’s a turnaround story so rosy that CEO Tim Mayopoulos expects Fannie Mae to be “profitable for the foreseeable future,” and the government projects it will actually benefit from the bailout it gave the mortgage giant by 2023. (The entity has paid back $35.6 billion of $116 billion so far). The outlook has left some observers wondering whether this year’s fortunes will erode ambitions — borne out of the financial crisis — to overhaul the agency.
