While both the 10- and 20-city composites posted monthly declines, falling 0.2% and 0.1% respectively, the drops were caused by seasonal factors. Once seasonally adjusted, the two composites showed improvements of 0.5% and 0.6% compared with October, and seasonally adjusted prices were higher in 19 of the 20 metros tracked.

Year over year, the 10-city was up 4.5% and the 20-city gained 5.5%. Phoenix far outperformed any other metro area tracked with a 22.8% price jump compared with the previous year, while New York registered the only year-over-year decline with a fall of 1.2%.

The widespread improvements are stemming from three major factors, according to Patrick Newport and Stephanie Karol, economists at IHS Global Insight, who attributed the gains to economic growth and improvements in the job market; falling inventories of for-sale homes as replacement demand and demand from newly formed households outpaces starts; and low interest rates. “These three drivers will keep home prices moving up in 2013.”
