The National Association of Home Builders (NAHB) released its Housing Market Index (HMI), showing another monthly gain — its ninth in a row.

The HMI — a gauge of homebuilder confidence — rose 1 point to 47 in December 2012, lifting the index to its highest levels since April 2006.

Readings under 50 indicate unfavorable housing conditions for builders. Readings over 50 signal “good” conditions. Coincidentally, the last time that the HMI read above 50 was April 2006, too.

The Housing Market Index is based on a survey which the NAHB sends to its members. The survey asks the nation’s builders to rate the current housing market conditions.

In December, home builders reported gains in two of the three areas surveyed:

• Current Single-Family Sales: 51 (+2 from November 2012)
• Projected Single-Family Sales: 51 (-1 from November 2012)
• Buyer Foot Traffic: 36 (+1 from November 2012)

It’s noteworthy that buyer foot traffic has climbed over nine straight months and is now at it’s highest reported level in nearly 7 years. Low mortgage rates and rising home prices throughout Columbus have compelled today’s renters and existing homeowners to consider their home buying options.

This was none more apparent that in the Northeast Region in which builder confidence grew twelve points to 42. The Midwest Region also showed a strong improvement, climbing 2 points to 53. The West and South regions fell slightly between November and December.

For today’s buyers, rising builder confidence may be a signal that home prices are headed higher. Confident home sellers — including the nation’s builders — are less likely to make price concessions into an improving market, or may be less likely to offer free upgrades to buyers.

Therefore, if you are in the market for a newly-built home, consider that you may get the best “deal” by acting sooner rather than later. Mortgage rates are rising and home prices are, too. Six months from now, your costs of homeownership may be higher.
