Over the past 23 years, 174 low-to-moderate income, single-parent families in 18 cities spread across 11 states have walked for the first time into the first houses they have ever owned, expecting them to be empty. So it is always a surprise for the new homeowners, one which usually moves them to tears, when they discover that the rooms have been fully furnished and decorated, that the cupboards and refrigerators are stuffed with food and cookware, and that the closets and garages brim with cleaning supplies and lawncare equipment. While the furnishings are tailored to the needs of each family, almost all of them have been greeted by the same three things: an oversized check for $5,000 to help with the down payment; the smiling face of the NFL’s 23rd all-time rushing leader; and, in a glass dish on the dining room table, a fresh apple pie.
