Mortgage rates remained near record lows Friday in quiet trading. No key economic data will be released today. Next week will bring a slew of economic news, and rates may be volatile. Existing Home Sales come out on Tuesday, New Home Sales and the Fed’s FOMC meeting on Wednesday, Durable Goods Orders on Thursday, and final first quarter GDP figures on Friday. The Treasury will hold large auctions of 2-, 5-, and 7-year notes beginning Tuesday.
