Yep it’s been very low since 2010, but looks like it’s been above 5% for possibly more than half the time since 1954, and there was a long stretch from around 1978-1991 where 6% was the minimum, and brief periods where it got to almost 20%. I feel for the poor people who bought houses with an 18% interest rate, I hope every single one refinanced quickly…
