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 11 a month (Redfin, 3-month rolling data through August 2026).

On the shelf — homes for sale at the end of the period: 27.

Going out — closed sales: about 11 a month.

The ladder: homes for sale ÷ monthly sales = 2.5 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 0 more homes came on than sold each month, so inventory is growing. The basin is filling.

Homes sold: about 11 a month in August 2026 (Redfin).

The 2015–2019 level for the same month was 5 — so sales ran at 220% of it, and below it in 6 of the last 24 months.
