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 100 a month (Redfin, 3-month rolling data through August 2026). That is 90% of the 2015–2019 level for the same months.

On the shelf — homes for sale at the end of the period: 235. That is 112% of the 2015–2019 level for the same months.

Going out — closed sales: about 73 a month. That is 75% of the 2015–2019 level for the same months. The drain is drawn 36% narrower: the share of homes for sale that sell each month is 64% of its 2015–2019 level.

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.

The net reading: about 27 more homes came on than sold each month, so inventory is growing. The basin is filling.

Homes sold: about 73 a month in August 2026 (Redfin).

The 2015–2019 level for the same month was 88 — so sales ran at 83% of it, and below it in 21 of the last 24 months.
