AMI (Area Median Income)

The median family income for a defined geographic area, published annually by FFIEC and used to qualify borrowers for income-restricted loan programs.

AMI is the foundational input for income-eligibility programs (HFA, USDA, some Fannie/Freddie products with affordable-housing overlays). FFIEC publishes county- and metro-level AMI tables annually; family-size adjustment factors scale the median by household size.

A borrower's "percent of AMI" is computed as (annualIncome / adjustedMedian) * 100. Programs cap eligibility at thresholds like 80% AMI (low-income), 100% AMI (moderate-income), or 120% AMI (some HFA tiers).
