Traditional adjustable-rate mortgages are rapidly becoming a remnant of the past, a new Freddie Mac survey suggests. Reporting on the results of its annual ARM survey, Freddie noted that just 56 percent of lenders in 2005 offered traditional 1-year adjustable-rate mortgages - the lowest percentage in the 22 year history of the GSE’s poll. Meanwhile, hybrid ARMs have gained in popularity, accounting for nearly four out of every five new ARMs originated last year.
