Methodology
Every county figure for New Mexico uses the county's own median home value and median household income from the Census American Community Survey 5-year estimates, a 20% deposit, and the current 30-year fixed rate from FRED (MORTGAGE30US) amortised over 30 years.
The share shown is annualised principal and interest divided by median household income. Property tax, insurance and HOA dues are excluded so the comparison between counties stays like-for-like.
Counties without both a published home value and a published income are left out entirely rather than filled with an estimate, so the table is shorter than the county list in some states.
