According to Frank Nothaft, vice president and chief economist, Freddie Mac:

"Most mortgage rates eased to all-time record lows this week as fourth quarter growth in the economy fell short of market projections. The Gross Domestic Product rose 2.8 percent in the final three months of 2011, below the market consensus forecast of 3.0 percent, while consumer spending in December was flat. One bright spot, however, was that fixed residential investment increased for the third consecutive quarter and residential construction spending rebounded in December, rising 0.7 percent."
