Start with the typical home: $569,055. Put 20% down and borrow $455,244 at 7.40%, the 30-year fixed average as of October 8, 2026.

That is $3,152 a month in principal and interest.

The median household here earns $106,857 a year, $8,905 a month. So the payment takes 35.4% of income — rated “stretched” (Lotvox ZIP bands: under 28% affordable · 28–36% stretched · 36%+ severe).

The line holds today's rate fixed and moves only the price: at that rate, the same share was 9.5% 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 $913.

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 76% of the 2015–2019 level for the same months.

On the shelf — homes for sale at the end of the period: 53.

Going out — closed sales: about 13 a month.

The ladder: homes for sale ÷ monthly sales = 3.97 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 8 more homes came on than sold each month, so inventory is growing. The basin is filling.
