The line holds today's rate fixed and moves only the price: at that rate, the same share was 8.8% in 2000.

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 22 a month (Redfin, 3-month rolling data through August 2026). That is 71% of the 2015–2019 level for the same months.

On the shelf — homes for sale at the end of the period: 74.

Going out — closed sales: about 24 a month. That is 89% of the 2015–2019 level for the same months.

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 2 more homes sold than came on each month, so inventory is shrinking. The basin is draining.

Homes sold: about 24 a month in August 2026 (Redfin).

The 2015–2019 level for the same month was 22 — so sales ran at 109% of it, and below it in 19 of the last 24 months.
