Nonprofits participating in one of FHA’s nonprofit programs must serve Low- to Moderate-Income individuals or families. Low- to Moderate-Income individuals or families refer to individuals or families whose household income does not exceed 115 percent of the median income for the area when adjusted for family size. The jurisdictional Homeownership Center (HOC) may approve a higher percentage of up to 140 percent.
Area median income data can be found at http://www.huduser.org/portal/datasets/il.html
