Monthly cost vs. price
Start with the typical home: $622,653. Put 20% down and borrow $498,122 at 7.40%, the 30-year fixed average as of October 8, 2026.
That is $3,449 a month in principal and interest.
The median household here earns $160,417 a year, $13,368 a month. So the payment takes 25.8% 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 9.3% in 2000.
