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 43 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: 102.

Going out — closed sales: about 30 a month. That is 66% of the 2015–2019 level for the same months. The drain is drawn 29% narrower: the share of homes for sale that sell each month is 71% of its 2015–2019 level.

The ladder: homes for sale ÷ monthly sales = 3.4 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 14 more homes came on than sold each month, so inventory is growing. The basin is filling.
