30-year fixed rate used: 6.76% (observed 2026-09-10, FRED MORTGAGE30US).

State detail

Methodology

For each state we take the median home value and the median household income from the Census American Community Survey 5-year estimates, apply a 20% deposit, and amortise the remaining balance over 30 years at the current 30-year fixed rate published by Freddie Mac and distributed through FRED (MORTGAGE30US).

The metric is the resulting monthly principal and interest, annualised, as a share of median household income. Taxes, insurance and HOA dues are deliberately excluded so the figure isolates the price-and-rate effect; every state is treated identically.

The twelve-month comparison holds home values and incomes fixed and re-prices them at the rate observed a year earlier, so the change you see is the rate effect on its own. Every figure recomputes the moment a new rate observation lands.

A state with no published home value or income is not shown rather than estimated.
