Savi primarily works with federal student loan programs and, unfortunately, private loans do not qualify for federal Income-Driven Repayment plans or for federal student loan forgiveness. The only loan types eligible for these programs are federal Direct loans or other federal loans that have been consolidated to Direct Consolidation Loans.
The only thing we could recommend for you to explore at this point is refinancing your private loan. There may be some benefits to refinancing your loans, such as reducing your interest rates or repayment amount. Savi is not a loan provider or bank, and this type of action is not something we service at this time.
