I was looking back at mortgage interest rates from December 2022 and noticed something interesting about how the market was shifting. The 30-year fixed was sitting around 6.66%, which had actually dropped from the week before. What caught my eye was the gap between the 30-year and 15-year options—the shorter mortgage was at 6.00%, a meaningful difference if you could handle the higher monthly payments.

The whole mortgage interest rates landscape back then showed some volatility. Jumbo mortgage rates were tracking slightly higher at 6.70%, while ARM products like the 5/1 ARM were cheaper at 5.45%. I remember experts were predicting rates could go even higher by year-end, with forecasts ranging up to 7%. For anyone looking at refinancing options in that period, the rate environment was definitely something to monitor closely.

What's interesting now looking back is how december 2022 represented a turning point—rates had climbed significantly through the year, and the debate was whether they'd keep rising or start to stabilize. The monthly payment math was pretty stark: on a $100,000 loan at those 30-year mortgage interest rates, you'd be looking at around $643 monthly, with over $131k in total interest. Definitely made the case for shopping around and locking in rates when they looked competitive.
