The Case-Shiller Home Price Index, which is considered the “gold standard” for appreciation, showed home prices rose 0.8% in October and 19.1% year over year, which was slightly lower than the previous reading of 19.5%. Why are the year over year appreciation figures declining, and does this mean home prices are moving lower? The pace of appreciation month over month is decelerating, but we are still seeing home price gains. When we look at the figure for last October, home prices rose 1.51%. Today’s figure, which was for October, came in at 0.8%. Because it’s a slower pace of appreciation, the year over year figure declined, but home prices are still rising and increasing.
