Why do income limits matter to a home buyer?
Most down payment assistance, mortgage credit certificates and state first-time buyer programs cap eligibility at a share of area median income, usually 80% to 120% or 140% of AMI. Fannie Mae's HomeReady and Freddie Mac's Home Possible loans cap at 80% of AMI in most areas. Check the program's own limit; each one sets its own multiple and household-size rule.
Is 80% of AMI the same as HUD's low-income limit?
Not always. HUD adjusts the published limits for high housing costs, statutory caps and floors, so the low-income limit can differ from a straight 80% of the median. Programs that say "80% of AMI" usually mean the HUD limit in this table, but some compute their own figure.
