I was looking back at mortgage data from April 2023 and found some interesting rate trends from that period. Back then, the 30-year fixed was hovering around 6.93%, which was actually down slightly from 6.95% the week before. The 15-year fixed was at 6.34%, and that one had ticked up 0.11% week-over-week. Pretty wild how much rates were moving around in that timeframe.

What caught my attention was the spread between different loan types. The 5/1 ARM was sitting at 5.74%, which gave borrowers some breathing room compared to the fixed options. And jumbo mortgages were tracking at 6.98% for 30-year fixed - basically in line with the standard 30-year rates. If you were looking at a $100,000 loan back then at those April 2023 mortgage rates, you'd be paying around $661 monthly on the 30-year, or $862 on the 15-year.

The APR on these loans was slightly higher than the headline rate since it factored in lender fees. For the 30-year, APR was 6.95% versus the 6.93% rate. That difference matters when you're calculating total cost over the life of the loan - we're talking $137,000+ in interest on a $100k mortgage over 30 years at those rates.

Interesting to look back at how the market was positioned back then. The 52-week low for jumbo rates was 5.19%, so rates had climbed pretty significantly from that point.
