As part of our "Buy Now, Pay Later" series — produced in partnership with Next Avenue, a nonprofit news platform for older adults produced by Twin Cities PBS — we'll hear firsthand from 70-year-old Loreli Taylor, a Social Security beneficiary who took out student loans decades ago and still has debt to pay down. She's not alone; the number of student loan borrowers 62 and older is up sharply. Also, borrowing rates are rising.
