The 20-city index of property values increased 5 percent from a year earlier, after rising 5.2 percent in the prior month, S&P CoreLogic Case-Shiller data showed Wednesday.
The median estimate in a Bloomberg survey of economists called for a gain of 4.9 percent. Nationally, home prices climbed 5.5 percent from October 2017.
The data showing the slowest pace of price gains in two years are the latest signs housing is in a broad slowdown, with sales and building also showing recent signs of weakness. The seasonally adjusted 20-city index gained 0.4 percent from the prior month, versus an 0.3 percent estimate.
