Start with the typical home: $392,638. Put 20% down and borrow $314,110 at 7.40%, the 30-year fixed average as of October 8, 2026.

The line holds today's rate fixed and moves only the price: at that rate, the same share was 11.8% 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 39 a month (Redfin, 3-month rolling data through August 2026). That is 91% of the 2015–2019 level for the same months.

On the shelf — homes for sale at the end of the period: 95.

Going out — closed sales: about 26 a month. That is 81% of the 2015–2019 level for the same months.

The ladder: homes for sale ÷ monthly sales = 3.6 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 13 more homes came on than sold each month, so inventory is growing. The basin is filling.

Homes sold: about 26 a month in August 2026 (Redfin).

The 2015–2019 level for the same month was 28 — so sales ran at 93% of it, and below it in 12 of the last 24 months.
