Freddie Mac last week said it will tweak its eligibility requirements to be more in line with Fannie Mae and expand the pool of its borrowers eligible to refinance through the recently revised Home Affordable Refinance Program. Under Freddie’s Relief Refinance Mortgage Program – which includes HARP – the requirements for refinancing will be aligned for mortgages with loan-to-value ratios that are equal to or less than 80 percent. Fannie’s HARP refi program currently makes no distinction between loans that are above or below 80 LTV, while Freddie draws a line in a number of areas for borrowers going through HARP at their existing servicer.
