A pair of newly filed bills by a lone Senate Democrat would see the Home Affordable Refinance Program further expanded as a means to provide underwater homeowners with new refi options. The Rebuilding American Homeownership Act, S. 1375, would modify HARP to allow loans “that lack a government guaranty” to be refinanced through HARP. The bill would also direct Fannie Mae and Freddie Mac to price for the risk that the GSEs would be assuming, so that the program has no net costs, as well as establish an automatic sunset for the program after 24 or 36 months.
