From your article:

Falling prices have made real estate the best buy in at least four decades. Housing affordability reached a record in December, according to National Association of Realtors data that go back to 1970. The group bases its gauge on property prices, mortgage rates and the median U.S. income[emphasis added]

But not rising health care costs, child care costs, energy costs, the price of food, etc., etc.... Never trust the NAR.
