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 DC area* as of November:
Month to Month: Down 2.4%
Year to Year: Down 19.4%
Change from Peak: Down 28.1% in 30 months
The following chart shows the DC HPI scaled such that the May 2006 peak is 100% on the y-axis. Data on the x-axis is scaled to display the last time (pre-peak) the DC HPI was at or lower than it was in the latest data (April 2004).
DC’s Case-Shiller HPI has been declining at a highly uniform rate for the last three months, and since we’re heading into winter with this data update, it may even speed up over the next few months.
Here’s a chart of Case-Shiller HPIs for all the markets that Redfin serves, so you can compare DC’s performance to other areas across the country:
DC’s HPI continues to come in higher than any other Redfin market, indicating the most overall price growth since 2000, for whatever that’s worth.
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.
DC is still tracking fairly closely to the ground covered by price drops in San Diego six months prior, putting it as one of the more rapidly-declining markets. Great news for homebuyers looking for a deal lately, if you can stomach the possibility of further declines. With this latest data, price declines still do not appear to be approaching a bottom.
