With more than two years left to go in the Home Affordable Refinance Program, it remains to be seen how many HARP-eligible loans will ultimately be refinanced as borrower education and lender participation in the program continue to be major challenges, according to a recent report by the Federal Housing Finance Agency’s official watchdog. In its “mid-program assessment,” the FHFA’s Office of Inspector General report noted that since HARP was launched in March 2009 through March 2013, 2.4 million HARP refis have been completed. The HARP 2.0 modifications rolled out in late 2011 and subsequent changes made throughout 2012 and 2013 have “substantially increased” the program’s refi volume, particularly for loans with loan-to-value ratios greater than 105 percent, said the OIG.
