Case-Shiller: Seattle Price Drops Still Playing Catch-Up
I apologize again for the multi-week radio silence here. We’ve revamped our data delivery to be able to better streamline the whole process, and from now on there will be a regular schedule of in-depth data in this space. For now though, it’s time for our monthly check-in of the S&P/Case-Shiller Home Price Indices (HPI).
For an explanation of how the Case-Shiller data is calculated, check out their methodology pdf. Also remember that the data released on the last Tuesday of a given month is for the period two months prior (i.e. – November data is released in January).
Here are the basic Case-Shiller stats for the Seattle area* as of November:
November 2008
Month to Month: Down 2.5%
Year to Year: Down 11.2%
Change from Peak: Down 13.6% in 16 months
The following chart shows the Seattle HPI scaled such that the July 2007 peak is 100% on the y-axis. Data on the x-axis is scaled to display the last time (pre-peak) the Seattle HPI was at or lower than it was in the latest data (January 2006).

With last month’s drop in Seattle’s Case-Shiller HPI, prices have now effectively “rewound” just under three years.
Here’s a chart of Case-Shiller HPIs for all the markets that Redfin serves, so you can compare Seattle’s performance to other areas across the country:

And here’s one more chart, in which I have lined up the peak Case-Shiller HPI value for each of Redfin’s markets, so we can see how long each market has been declining, and how much it has dropped from the peak.

Of the seven Case-Shiller-tracked markets that Redfin serves, Seattle’s rate of decline since the local peak in home prices continues to be exceeded only by Los Angeles. Of the entire 20 cities tracked by Case-Shiller, only five cities—Miami, LA, Las Vegas, Atlanta, and Tampa—had experienced a larger overall drop at this point in their respective declines. Seattle’s relatively rapid price drops have price trends here quickly catching up to other major cities across the country.
*[Case-Shiller defines Seattle as the Seattle-Tacoma-Bellevue, WA Metropolitan Statistical Area, which includes all of King, Pierce, and Snohomish counties.]
