Mortgage rates fell last week, but so did record amounts of snow across much of the East Coast. That may be why total mortgage application volume dropped 2.6 percent on a seasonally adjusted basis for the week from the previous week, according to the Mortgage Bankers Association.

Mortgage applications to refinance did eke out a 0.3 percent gain from the previous week to their highest level since October, but they are still down 31.5 percent from a year ago, when rates were even lower.
