Mortgage rates remained almost the same for the week ending Sept. 24, according to Freddie Mac.

The 30-year fixed mortgage rate was unchanged at 5.04%, with an average 0.6 point. Yesterday, the Mortgage Bankers Association reported a 17.4% jump in its Refinance Index to 2882 for the week ending Sept. 18 in response to mortgage rates being the closest to below 5% since the end of May.

Until rates move significantly below 5%, Credit Suisse analysts expect refinance activity to remain relatively tame. They said that based on anecdotal evidence, recent origination has shifted to higher note rates, "which would dampen the refi response further from any given rate level."

In other terms, Freddie Mac reported the 15-year fixed mortgage rate averaged 4.46%, down one basis point from last week.

On the adjustable side, 5/1 hybrid ARMs were unchanged at 4.51%, while one-year ARM rates slipped six basis points to 4.52%
