The typical size of newly built single-family homes was effectively unchanged from the second to third quarter of 2015, posting a small quarterly decline.
As National Association of Home Builders tax and policy guru Robert Dietz notes, a growing force of first-time, entry-level buyers signals a "mix shift," away from higher-end, first- and second-time move-up, bigger homes as the only ones selling, to a more balanced dispersion across high and lower price points, and square footage. Dietz writes:
According to third quarter 2015 data from the Census Quarterly Starts and Completions by Purpose and Design and NAHB analysis, median single-family square floor area fell from 2,478 in the second quarter to 2,445 square feet. Average (mean) square footage for new single-family homes fell from 2,704 to 2,653 for the third quarter.
