Freddie Mac reported Thursday that mortgage interest rates have done a 180 and are now starting to climb, buoyed by positive housing data over recent weeks which show the market ended 2011 on a high note. The 30-year fixed-rate mortgage rose 10 basis points in one week’s time and is now averaging 3.98 percent, reversing its previous three-week trend of setting all-time record lows. Despite the jump, this marks the eighth consecutive week the 30-year fixed rate has remained below 4.00 percent. Article Feed
