2026-09-30
Redfin market data (county + ZIP), via Lotvox. As of 2026-09-30. Normal = same-month median of monthly rates, minimum 3 same-month points. Source window 3 months (flows shown per month). months_of_supply is not published at this grain (0 non-null rows measured); derived here as active listings / closed sales per month. A fresher supply-only read (46 new, 102 active, 2026-09-01, Realtor.com inventory (county + ZIP), via Lotvox) is available but is NOT used in the net — that source publishes no closed sales, so subtracting across it would mix two vintages.

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.

COUNTY · King, WA
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.
