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). That is 80% of the 2015–2019 level for the same months.

On the shelf — homes for sale at the end of the period: 70.

Going out — closed sales: about 17 a month.

The ladder: homes for sale ÷ monthly sales = 4.0 months of supply — inside the 4–6 month balanced range. In the basin, that is the water level against the shaded balanced band.

The net reading: about 4 more homes came on than sold each month, so inventory is growing. The basin is filling.

Homes sold: about 17 a month in August 2026 (Redfin).

The 2015–2019 level for the same month was 22 — so sales ran at 77% of it, and below it in 16 of the last 24 months.
