Leverage, and refinancing. It's not like taking a mortgage locks you at that market rate. With refinancing, you can take advantage of market rates to improve your leverage even more. I refinanced last year to a 15-year mortgage at a sub-2% rate. The math happened to work out that my payments didn't change, but it halved the amount of my payment going to interest each month. Which, in turn, accelerates my payoff date by about 10 years.
