He and his daughter live on Social Security and struggle to afford the cost of renovating their home. Medical professionals sometimes tell them they can’t continue living in the home’s rickety front porch ramp and shoebox bathroom and kitchen. The couple have applied for county, state and even federal assistance. Despite the financial challenge, they are determined to remain in their house as long as possible.
