Habitat for Humanity of Metro Louisville celebrated a milestone Thursday. But as the group’s work has been broadened in response to the mortgage crisis.After celebrating the construction of Habitat’s 300th home in Louisville, Executive Director Rob Locke said the group may soon get some new clients.“It’s certainly possible that families who have lost their homes due to foreclosure are eligible to buy habitat homes," he says. "To buy a habitat home you have to need it and you have to be able to afford it.”The group has recently refurbished homes under foreclosure and donated by banks.Locke says people who lost homes to foreclosure will qualify for Habitat homes once they rebuild their credit. Habitat for Humanity offers eligible families zero interest mortgages to purchase the dwellings.
