For more than two decades, Kimberly Burnworth has lived in a mobile home in rural West Virginia on a tract her grandfather acquired in the 1960s. A single mother, Burnworth is paid by the government to be a caregiver to her 11-year-old son, David, who has muscular dystrophy. Between food, medicines and a $61,000 mortgage, money is a constant worry. Increasingly, Burnworth is also worried she will be evicted. She has not made a mortgage payment in nearly two years after losing her job. The lender — 21st Mortgage, a company controlled by Warren Buffett’s Berkshire Hathaway — is trying to foreclose on her home. And the federal moratorium on evictions put in place during the pandemic is ending this month.
