After seasonal adjustments, home prices in November rose 0.9%, according to S&P/Case-Shiller's 20-city composite index. On a year-over-year basis, home prices rose 13.7% in November, the fastest growth in more than seven years. Pent-up demand and low inventories of homes for sale have been supporting price growth.
