Interesting S&P Case-Shiller Index for San Francisco Real Estate Prices

This S&P Case-Shiller Index is very interesting. The prices for homes in the upper third of prices – which dominate in most of San Francisco, central and southern Marin, and central Contra Costa – ticked down a tiny bit in summer, exactly as they did last summer. These short-term fluctuations are common and not particularly meaningful until substantiated by a longer-term trend.

Since Case-Shiller’s SF Metro Area covers 5 counties, it should be noted that not all the markets within the Area move in lockstep: activity and appreciation rates can vary significantly.

As is clearly illustrated below, for the past 4 years, spring has been the big driver of home-price appreciation. Prices generally plateau in subsequent seasons until the next spring arrives. For the past couple years, the spring selling season has started very early, in late January or early February, due to the incredible weather we’ve had in those months. El Niňo, if it arrives, might move the spring pick-up in sales back to mid-March/early April in 2016.
