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.

  • 5/mofall in the monthly rate (47%)— peak 11/mo (2025-07-31) to 6/mo now
  • 66transactions that did not happen— summed monthly shortfall vs the same-month normal, over 23 months below it (vs 2015-19 (COVID excluded))
  • 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 (10 new, 14 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.
