Just dug through some old mortgage rate data from April 2023 and it's interesting to see how much things have shifted. Back then, the average 30-year fixed was sitting around 6.93% while 15-year mortgages were at 6.34%. People were paying roughly $661 monthly on a $100k loan at those rates. The jumbo mortgage market was even higher at 6.98%. What caught my attention was how the 15-year rates were climbing that week while the 30-year stayed pretty flat. If you had locked in a 5/1 ARM back in April 2023, you'd be looking at 5.74% - which honestly seemed like a decent option for people planning shorter holds. The real thing to understand from those April 2023 mortgage rates was the APR breakdown. Most people only look at the interest rate, but APR includes all the fees and charges too, which usually pushed the total cost higher. On that $100k example, you'd end up paying like $137k in total interest over 30 years when you do the full math. Comparing it to the 52-week lows at that time, rates were still elevated - the 15-year had dipped to 4.60% earlier in the year, so April was definitely on the higher side. Interesting snapshot of where the mortgage market was positioned back then.
