NAR's oposition falls primarily in two areas: The PATH Act does not include an explicit federal guaranty and the bill dramatically restructures the FHA.
On average FHA took 340 days to sell REO properties based on dispositions from January 2008 through June 2012, compared to just over 200 days for Fannie, Freddie and VA.
FHFA sued UBS in 2011 over $4.5 billion in RMBS securities that the bank sponsored and $1.8 billion in third party RMBS sold to Fannie Mae and Freddie Mac.
