Case-Shiller Tiers: Low Tier Cooled Most in August

Let’s check out the three price tiers for the Seattle area, as measured by Case-Shiller. Remember, Case-Shiller’s “Seattle” data is based on single-family home repeat sales in King, Pierce, and Snohomish counties.

Note that the tiers are determined by sale volume. In other words, 1/3 of all sales fall into each tier. For more details on the tier methodologies, hit the full methodology pdf. Here are the current tier breakpoints:

  • Low Tier: < $286,378 (up 0.8%)
  • Mid Tier: $286,378 – $453,899
  • Hi Tier: > $453,899 (up 0.4%)

First up is the straight graph of the index from January 2000 through August 2013.
