Mortgage rates were slightly higher today, erasing some of the gains seen on Friday, but remaining well within the recent range. The most prevalently-quoted conforming 30yr fixed rate for top tier borrowers had clearly been 4.0% on Friday, but today’s weakness makes 4.125% nearly as common. That said, the shift isn’t due to the size of the move in rates today, simply the fact that we were very close to the edge of the range to begin with.
