The National Association of Home Builders (NAHB) reported the housing market index (HMI) was at 70 in December, up from 63 in November. Any number above 50 indicates that more builders view sales conditions as good than poor.

From the NAHB: Builder Confidence Closes Year on a High Note

Builder confidence in the market for newly-built single-family homes jumped seven points to a level of 70 on the National Association of Home Builders/Wells Fargo Housing Market Index (HMI). This is the highest reading since July 2005.

“Though this significant increase in builder confidence could be considered an outlier, the fact remains that the economic fundamentals continue to look good for housing,” said NAHB Chief Economist Robert Dietz. “The rise in the HMI is consistent with recent gains for the stock market and consumer confidence. At the same time, builders remain sensitive to rising mortgage rates and continue to deal with shortages of lots and labor.”

All three HMI components posted healthy gains in December. The component gauging current sales conditions increased seven points to 76 while the index charting sales expectations in the next six months jumped nine points to 78. Meanwhile, the component measuring buyer traffic rose six points to 53, marking the first time this gauge has topped 50 since October 2005.

Looking at the three-month moving averages for regional HMI scores, the Northeast rose six points to 51, the Midwest posted a three-point gain to 61, the South rose one point to 67 and the West registered a two-point gain to 79.
