Price bandsmix-shift

Price Bands — the median behind the median

A single median rises whenever expensive homes become a bigger share of what sells, even if no tier got more expensive. These are the tiers underneath it, computed from recorded arms-length deed transactions in King.

Current tiers · 12 months to Aug 25floor 10 sales/tier

1 tier had too few sales in this ZIP and are shown at county or metro level — see the stamp on each row. 6 tiers had too few sales at every level and are left blank rather than estimated.

No mix-shift history for this area. no geography from this ZIP up to metro has 8+ quarters of 10+ recorded arms-length sales across at least 4 price tiers. Trends are drawn only from recorded transactions; the last-sale snapshot above cannot carry a time series, because a property that sold twice keeps only its latest sale — which drags the history upward through the tiers and would invent the very mix shift this section exists to test for.

National context — not local

NAR's aggregate existing-home median for the United States and the West census region. This is the figure the tiers above are a check on. It is national/regional and says nothing about 98109.
