The 30-year fixed-rate mortgage fell 2 basis points to 3.44 percent this week. As mortgage rates continue to range between 3.41 and 3.48 percent, many are taking advantage of the historically low rates by refinancing. Since the Brexit vote, the refinance share of mortgage activity has remained above 60 percent.
