Monthly cost vs. price
Start with the typical home: $544,725. Put 20% down and borrow $435,780 at 7.40%, the 30-year fixed average as of October 8, 2026.
That is $3,017 a month in principal and interest.
The median household here earns $132,804 a year, $11,067 a month. So the payment takes 27.3% of income — rated “affordable” (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.

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 16 a month (Redfin, 3-month rolling data through August 2026).
On the shelf — homes for sale at the end of the period: 38.
Going out — closed sales: about 15 a month. The drain is drawn 30% narrower: the share of homes for sale that sell each month is 70% of its 2015–2019 level.
The ladder: homes for sale ÷ monthly sales = 2.5 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.
