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 14 a month (Redfin, 3-month rolling data through August 2026).

On the shelf — homes for sale at the end of the period: 25.

Going out — closed sales: about 17 a month.

The ladder: homes for sale ÷ monthly sales = 1.4 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.

The net reading: about 3 more homes sold than came on each month, so inventory is shrinking. The basin is draining.
