The line holds today's rate fixed and moves only the price: at that rate, the same share was 11.4% in 2000.

Take the typical home's price each month, borrow 80% at that month's actual 30-year average rate: in January 2000 (8.21%) the payment was $620.

In December 2020, with rates at 2.68%, it was $870.

General prices (CPI-U) rose +97% over the same span.

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 30 a month (Redfin, 3-month rolling data through August 2026). That is 83% of the 2015–2019 level for the same months.

On the shelf — homes for sale at the end of the period: 133.

Going out — closed sales: about 20 a month. The drain is drawn 26% narrower: the share of homes for sale that sell each month is 74% of its 2015–2019 level.

The ladder: homes for sale ÷ monthly sales = 6.5 months of supply — above the 4–6 month balanced range. In the basin, that is the water level against the shaded balanced band.

The net reading: about 10 more homes came on than sold each month, so inventory is growing. The basin is filling.

Homes sold: about 20 a month in August 2026 (Redfin).

The 2015–2019 level for the same month was 24 — so sales ran at 83% of it, and below it in 21 of the last 24 months.
