No, not this kind of harp The chief economist for Freddie Mac says that the recent changes made by the Obama Administration to HARP — the Home Affordable Refinance Program — could result in an additional $200 billion to $300 billion in mortgages over the next two years.

With that, Freddie Mac joins a chorus of organizations that see the revised HARP having a significant effect on the housing market. Both the Federal Housing Finance Agency and Moody’s Analytics said they expect HARP 2.0 to result in 1.6 million refinanced mortgages, while Keefe, Bruyette & Woods analysts said they expect refinances through HARP to increase 10% in both 2012 and 2013.
