What to Consider Before Refinancing
Before choosing a lender, keep these in mind:
-
Do you have federal loans? You may lose federal protections (like income-driven repayment and forgiveness programs).
-
What’s your credit score? Better scores mean better interest rates.
-
Can you add a co-signer? If your credit is limited, a co-signer can help.
-
Fixed vs Variable APR: Fixed rates stay the same; variable rates may rise.
Conclusion
Student loan refinancing in 2025 can help you manage your debt smarter — but only if you pick the right lender.

Always compare rates, terms, and borrower protections before committing.
