Monthly cost vs. price
Start with the typical home: $540,382. Put 20% down and borrow $432,306 at 7.40%, the 30-year fixed average as of October 8, 2026.
That is $2,993 a month in principal and interest.
The median household here earns $124,219 a year, $10,352 a month. So the payment takes 28.9% 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 9.7% in 2000.
