Sales Outpacing Starts by a Historic Margin

Among this year’s most read stories on the National Association of Home Builders Eye on Housing blog was an October post, showing that the gap between sales and construction was the largest on record. After a decline during the spring, NAHB chief economist Robert Dietz noted that home building began staging a dramatic rebound helped by low mortgage interest rates, a growing preference for living in the suburbs, and favorable demographics.

Indeed, the count of such home sales is up 69% compared to a year ago, an incredible jump. To place the current data into context, I smoothed the data using 6-month moving averages.
