The White House is backing a trio of Senate bills filed last week to expand the Home Affordable Refinance Program to an even wider circle of underwater borrowers as part of the Obama administration’s re-election “to-do list.” The Equity Rebuilding Act sponsored by Sen. Jeff Merkley, D-OR, would lower costs for some homeowners seeking to refinance through HARP. Under the bill, homeowners who are current on their mortgage seeking to refi into a 20-year loan term or shorter would have their closing costs covered by Fannie and Freddie. A second bill by Sen. Dianne Feinstein, D-CA, the Expanding Refinancing Opportunities Act of 2012, would create a $6 billion FHA fund to provide insurance for underwater homeowners who currently don’t have a federally backed loan. To pay for the FHA extension, Feinstein would extend by one year the temporary, 10-year, 10 basis point increase of the GSE guarantee fee that took effect April 1.
