Monthly cost vs. price
Start with the typical home: $459,968. Put 20% down and borrow $367,974 at 7.40%, the 30-year fixed average as of October 8, 2026.
That is $2,548 a month in principal and interest.
The median household here earns $85,132 a year, $7,094 a month. So the payment takes 35.9% 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 12.3% 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 48 a month (Redfin, 3-month rolling data through August 2026). That is 60% of the 2015–2019 level for the same months.
On the shelf — homes for sale at the end of the period: 76.
Going out — closed sales: about 43 a month. That is 57% of the 2015–2019 level for the same months. The drain is drawn 58% narrower: the share of homes for sale that sell each month is 42% of its 2015–2019 level.
The ladder: homes for sale ÷ monthly sales = 1.8 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 5 more homes came on than sold each month, so inventory is growing. The basin is filling.
