Monthly cost vs. price
Start with the typical home: $1,147,961. Put 20% down and borrow $918,369 at 7.40%, the 30-year fixed average as of October 8, 2026.
That is $6,359 a month in principal and interest.
The median household here earns $198,243 a year, $16,520 a month. So the payment takes 38.5% of income — rated “severe” (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 12.2% in 2000.

Listings Flow Ladder
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 42 a month (Redfin, 3-month rolling data through August 2026). That is 98% of the 2015–2019 level for the same months.
On the shelf — homes for sale at the end of the period: 121.
Going out — closed sales: about 41 a month. That is 90% of the 2015–2019 level for the same months. The drain is drawn 18% narrower: the share of homes for sale that sell each month is 82% of its 2015–2019 level.
The ladder: homes for sale ÷ monthly sales = 3.0 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 1 more homes came on than sold each month, so inventory is growing. The basin is filling.
