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 48 a month (Redfin, 3-month rolling data through August 2026). That is 73% of the 2015–2019 level for the same months.

On the shelf — homes for sale at the end of the period: 85. That is 52% of the 2015–2019 level for the same months.

Going out — closed sales: about 40 a month. That is 70% of the 2015–2019 level for the same months.

The ladder: homes for sale ÷ monthly sales = 2.1 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 9 more homes came on than sold each month, so inventory is growing. The basin is filling.
