How plugged is the drain? Two definitions, both ours, deliberately not reconciled.
- 37%Absorption vs its own normal— 1 - (closed sales / active listings) / same-month median of that ratio
- 22%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.
- 148/mofall in the monthly rate (31%)— peak 482/mo (2025-06-30) to 334/mo now
- 1,864transactions that did not happen— summed monthly shortfall vs the same-month normal, over 21 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.
Redfin market data (county + ZIP), via Lotvox. As of 2026-09-30. Normal = same-month median of monthly rates, minimum 3 same-month points. A fresher supply-only read (540 new, 1,418 active, 2026-06-01, 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.

Supply structure
No place-level projection exists; this is today's structure.
The 75+ share of owner stock moved 0.1 points across a decade of ACS vintages (14.94% in 2019 to 15.06% in 2023, county average). The exposure is where it is, not arriving.
