Mortgage rates had a bad October. November hasn't exactly been great either, with last Thursday being one of the worst days of the year in terms of day-over-day jumps in rates. In addition to the abrupt move, last week's weakness also brought rates in line with their highest levels in more than 3 months.
All of the above could be part of a bigger shift away from the prevailing trend toward lower rates (which had been intact since last November) and into a new trend of rising rates. This newer, unfriendlier trend arguably tried to make an appearance in mid September but was quickly shut down as rates nearly returned to the super-long-term lows
