Builder confidence took a steep dive this month, reflecting increasing news of slowing home sales and rising concerns over affordability. The National Association of Home Builders (NAHB) said its Housing Market Index (HMI), a joint project of NAHB and Wells Fargo, dropped eight points. The index, which has been floating in the 67 to 70 range since March, had a November level of 60, the lowest since July 2016.
