According to the Federal Housing Financing Agency, if your loan is Fannie Mae or Freddie Mac owned, and your current home loan is no more than 125% of its current market value, you may be eligible for refinancing under the HARP loan refinancing guidelines.

I just interviewed my lenders on this topic.  They have been successful with the program.  However, if your loan is Freddie Mac, then you should contact your current lender for help.  If your loan is Fannie Mae, then any lender, preferably mine, can help you.

From the sources that I have read, rates are priced slightly higher than market by about 1/8% to 1/4%

Considering the high LTV of these loans, that is actually very good.  Call me so that I can put you in touch with someone who can help.
