How plugged is the drain? Two definitions, both ours, deliberately not reconciled.
—Absorption vs its own normal— 1 - (closed sales / active listings) / same-month median of that ratio
—Closed sales vs its own normal— 1 - closed sales per month / same-month median closed sales per month
Closed sales over 24 months — two different numbers, deliberately not merged.

rate_drop_from_peak is a change in the monthly rate; cumulative_shortfall_vs_normal counts transactions not transacted. They are different quantities and are not interchangeable.
2026-08-31
Redfin market data (county + ZIP), via Lotvox. As of 2026-08-31. 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 (4 new, 12 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.

ZIP
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
