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

On the shelf — homes for sale at the end of the period: 92.

Going out — closed sales: about 14 a month.

The ladder: homes for sale ÷ monthly sales = 6.7 months of supply — above the 4–6 month balanced range. In the basin, that is the water level against the shaded balanced band.
