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 55 a month (Redfin, 3-month rolling data through August 2026). That is 60% of the 2015–2019 level for the same months.

On the shelf — homes for sale at the end of the period: 114.

Going out — closed sales: about 37 a month. That is 46% of the 2015–2019 level for the same months. The drain is drawn 55% narrower: the share of homes for sale that sell each month is 45% of its 2015–2019 level.

The ladder: homes for sale ÷ monthly sales = 3.1 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 18 more homes came on than sold each month, so inventory is growing. The basin is filling.

Homes sold: about 37 a month in August 2026 (Redfin).

The 2015–2019 level for the same month was 69 — so sales ran at 54% of it, and below it in 24 of the last 24 months.
