Yesterday's Ticker story on a new affordable housing development unintentionally caused confusion about how Habitat for Humanity determines the price of a home per family. The article incorrectly described potential building costs as the price of a home. The following explains the dynamics of a Habitat mortgage: The price of the home is made affordable for each individual family through a 0% interest mortgage, sweat equity hours, homeowner advocacy and in-kind donations. The homes are mortgaged for each family situation, serving those families below 60 percent of the area’s median income. Additionally, Habitat's goal is to develop the first net-zero Habitat community in Michigan.
