Picture the Listings Flow Ladder as a basin: new listings pour in from the faucet, the homes for sale are the water, and closed sales run out the drain. Coming in — new listings: about 103 a month (Redfin, 3-month rolling data through August 2026). That is 65% of the 2015–2019 level for the same months.

The ladder: homes for sale ÷ monthly sales = 3.2 months of supply — below the 4–6 month range Lotvox treats as balanced. In the basin, that is the water level against the shaded balanced band.
