Home prices dip in slowdown

Home prices in the nation’s 20 biggest cities dipped 0.1 percent in October from the prior month but rose strongly from the same month last year, according to a closely watched index, indicating the start of the seasonal slowdown in home prices.

It was the first month-over-month dip after six months of gains for the Standard & Poor’s/Case-Shiller index of 20 large cities. The index was up 4.3 percent compared with October 2011.
