How to read this
Reductions are detected by comparing each listing’s asking price night over night in the MLS feed; a listing appears once per cut, and the share reduced counts each listing once. Relists at a new price under a new MLS number are not matched. Prices are asking prices. Source: live MLS feeds compiled by Momentum Research, updated October 23, 2026.
