Mortgages modified by Fannie Mae and Freddie Mac performed about the same for a year after modification but Freddies loans had a slightly worse performance starting some 18 months after modification, according to the Office of the Comptroller of the Currency. The OCC Mortgage Metrics Report for the First Quarter of 2013 noted that Fannie and Freddie loans each had a 17 percent re-default rate six months after modification. The two GSEs were similarly tied at the 12-month mark, each posting a 24.4 percent re-default rate. Daylight begins to crack between the two GSEs at 18 months, with Fannies rate at an even 28.0 percent compared to Freddies 28.2 percent. At 24 months, Fannies mods saw a 29.4 percent re-default rate compared to Freddies 29.9 percent. The gap widens at 36 months when Fannie stood at 35.2 percent compared to Freddies 36.3 percent rate.
