Habitat for Humanity in Greeley said it will refurbish four foreclosed homes over the next year instead of building new ones. Mandy Ewing, the group's interim executive director, said the new approach was a decision by the group's board of directors and Dick Monfort, owner of the Colorado Rockies and a major contributor to the Greeley group. Andy Phelps, construction director for Greeley Habitat for Humanity, said some foreclosed houses in Greeley are "incredibly cheap." He said it makes sense to refurbish existing homes instead of building new ones. Habitat chapters in Phoenix, Dallas, Minneapolis, Milwaukee and other cities nationwide have taken a similar approach.Families must meet income requirements to qualify for a Habitat for Humanity home. They pay a mortgage that's not more than 30 percent of their income.The families must also attend classes and contribute 500 hours to Habitat, 300 of which must be actual construction on their new house.
