Chris Winiarz, a 31-year-old money manager with a Northwestern MBA, jumped at a student-loan deal of a lifetime.
A startup called SoFi offered to refinance his $45,000 in federal debt, slashing his interest rate to 2.69 percent from 6.55 percent. Winiarz will pay off his obligation three years early, saving about $9,500 and helping pay for an engagement ring for his girlfriend. The company even threw in a free bottle of artisan olive oil.
