Monthly cost vs. price
Start with the typical home: $663,911. Put 20% down and borrow $531,129 at 7.40%, the 30-year fixed average as of October 8, 2026.
That is $3,677 a month in principal and interest.
The median household here earns $101,250 a year, $8,438 a month. So the payment takes 43.6% 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 43.1% in 2022.
