Monthly cost vs. price
Start with the typical home: $727,903. Put 20% down and borrow $582,322 at 7.40%, the 30-year fixed average as of October 8, 2026.
That is $4,032 a month in principal and interest.
The median household here earns $104,840 a year, $8,737 a month. So the payment takes 46.1% 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 13.9% in 2000.
