Beyoncé and Jay-Z just purchased a $88 million home in Bel Air. The main premise of the article is that financing 60% of the purchase with an adjustable rate mortgage in the amount of $52.8 million is likely a good business decision. Mortgage rates continue to be historically low and therefore financing the purchase frees up their cash for other, more profitable ventures. That said, the median price of a home in Bel Air is $3.25 million and another axiom of wise home buying is not to buy the most expensive house on the block…unless you’re Beyoncé and Jay-Z that is!
