Area Median Income Data

The calculation for what is permanently affordable housing is complicated. Arlington’s affordable rate is based on a region that includes the Area Median Income (AMI) of the Cambridge-Boston-Quincy region. The rate is adjusted and reset periodically according to federal HUD guidelines. The rate is applied based on family size and on the Town’s definition of what income level is eligible for Inclusionary Housing opportunities in Arlington. In Arlington a 3 person family would qualify if their income was under 60% of AMI. At this time, that is approximately $58,000 for a family of three.
