"The all-time record low – since Freddie Mac began tracking mortgage rates in 1971 – was 3.31% in November 2012. Conversely, the all-time record high occurred in October of 1981, hitting 18.63%. That's more than four times higher than today's average 30-year fixed rate of 4.32% as of March 20...rates hovering around 4.5% may be high relative to last year, but something to celebrate compared to almost any year since 1971."
