What it is: You pay what you owe — missed payments plus fees and costs — and the loan goes back to normal, as if you never fell behind.
When it fits: The hardship was temporary. A job loss that's over, a medical bill that's paid, a rough patch that's behind you — and you can put together the full amount.
How it works: Ask your lender for a reinstatement quote. That gives you the exact number and a deadline. Get it in writing.
Watch out for: The number is often bigger than people expect once fees stack up, and it usually has to be paid in one lump sum.
