How to Refinance a Student Loan With Bad Credit

Most student loan refinancing lenders want a credit score somewhere in the mid-600s. With bad credit, that generally leaves three routes: bring in a cosigner, raise your score and apply later, or find one of the few lenders that underwrites distressed loans instead of credit scores.

There is a fourth possibility worth naming early. Refinancing is one instrument, and for some borrowers it is the wrong one — not because they cannot qualify, but because a lower interest rate does not solve the problem they actually have.

A score in the mid-600s is the usual floor. Minimums vary by lender and none of them are obligated to publish one, so treat any specific number you read as a rough marker rather than a rule. What is consistent is that refinancing is priced for borrowers who have already demonstrated they repay debt on time, which is the opposite of the position most people asking this question are in. If you want the detail on where those thresholds sit, we cover the credit score needed to refinance separately.

Your score is not the only input. Lenders also look at income, how stable your employment is, and your debt-to-income ratio — your monthly debt payments measured against your gross monthly income. A thin score with strong, verifiable income is a different application than a thin score with irregular income, and the two do not always get the same answer.

Prequalifying does not affect your credit. Applying does. Most lenders will quote you a rate using a soft credit inquiry, which leaves no mark. The hard inquiry comes when you move to a full application. Know which step you are on before you agree to it, because repeated hard inquiries while you are shopping will work against the score you are trying to protect.

A cosigner is the fastest route, and the one worth thinking hardest about. Adding someone with stronger credit to the application can turn a decline into an approval, and often into a better rate.

The part that usually goes unsaid is what a cosigner needs to be for this to work. A cosigner is equally liable for the whole balance, not a character reference — so the strategy only holds up if that person could actually carry the payment if you could not. Someone willing to cosign for a borrower with damaged credit is frequently not in a strong financial position themselves. When that is the case, the loan does not spread the risk, it doubles the exposure: if payments stop, two credit files take the damage instead of one, neither party is positioned to fund a settlement later, and the relationship absorbs the rest. Ask the lender about its cosigner release terms before you sign, so there is a defined way off.

Raising the score is slower and entirely within your control. On-time payments across every account, lower balances relative to your credit limits, and no new credit applications while you are rebuilding. Pull your reports from all three bureaus and check them for errors first — a paid-off account still reporting a balance is not unusual, and correcting it costs nothing.

Improving your debt-to-income ratio does the same work from the other direction. Paying down other balances or adding income both move the number lenders are actually underwriting.

Credit unions underwrite differently than national lenders. They are member-owned, their criteria vary widely, and a relationship you already have is worth a conversation. It is not a guarantee of a lower bar, but it is a different bar.

This is where most guidance on this topic stops being useful, because the answer changes completely.

Mainstream refinance lenders decline delinquent and defaulted loans outright. No amount of cosigner strength or rate shopping changes that. The loan status is disqualifying on its own.

Federal loans in default cannot be refinanced at all. There is no private refinancing path that replaces a defaulted federal loan while it remains in default. Getting out of default is a different process — rehabilitation or consolidation — and it has to happen first. We cover refinancing a defaulted student loan in full separately.

Private loans in default are the exception. A narrow set of lenders exists specifically to refinance private student loans that are delinquent or already charged off, underwriting the situation rather than the score. Being in default is a qualification there rather than a disqualification. The tradeoff is in the structure of the new loan rather than in the approval, so it is worth understanding what the deal actually costs before you apply — we walk through one of them in our guide to Yrefy student loan refinancing.

Some borrowers can qualify and still should not, and some cannot qualify and have better options than they realize. These are the ones lenders have no reason to raise.

Borrowing against your home is a real option with a bright line through it. Some guidance suggests using home equity or a second mortgage to clear education debt, usually without distinguishing between loan types. The distinction matters more than the advice does.

For federal loans, there is no case for it. The federal system already provides income-driven payment options and forgiveness paths, and no rate is worth putting a house behind a debt that already has affordable structures available to it.

For private loans, it can make sense — those loans have none of those safety valves, and if the rate gap is genuinely large it may be one of the few levers available. The question to carry into that decision is a simple one: why put your property at risk to deal with this debt, unless doing so is one of the very few options you have?

Settlement retires the debt for less than the balance. Private lenders will generally discuss a settlement once a loan has defaulted, because a defaulted balance is worth substantially less to them than its face value. It usually requires money up front, in one payment or over a short schedule, which is the fork — without a lump sum available, this door does not open regardless of how favorable the pricing looks.

It can sometimes make sense before default, too. Borrowers who conclude they will never get ahead of a balance, and who have already repaid more than they originally borrowed, often reach the view that settling is simply the fair resolution at that point. That is a judgment about your own situation rather than a financial calculation, and it is yours to make. We cover how student loan settlement works in more detail.

Bankruptcy is difficult, expensive, and available. Discharging student debt requires proving undue hardship, which is a real standard and not a formality. It is also not the dead end it is often described as, particularly for private loans. If your loans are private and the balance is not survivable, it belongs on the list of things to evaluate rather than off it.

Which of these fits is partly a question of appetite. Two borrowers with nearly identical numbers reasonably choose differently — one will take a cosigner and grind it out, another will let the loan default and negotiate, another will look at bankruptcy. The paths differ in what they cost you, how long they take, and how much uncertainty you are willing to sit with. If you want help thinking through which of these your situation actually supports, we can look at it with you.

Refinancing federal loans into a private loan is permanent, and it gives up the federal system entirely. Income-driven repayment, forgiveness programs, and federal default remedies all go with it. There is no path back.

That tradeoff has become harder to justify rather than easier. Federal repayment rules changed substantially in 2026, and the plans available now are not the ones most articles on this subject were written against. If your loans are federal, work out what your payment looks like inside the federal system before you consider leaving it, because leaving is the one decision here you cannot reverse.

Federal consolidation is a different thing from refinancing, and it does not require a credit check. It combines federal loans into one federal loan and keeps them federal. It will not lower your interest rate, and consolidating now has consequences for progress you have already made toward forgiveness, so it is worth understanding before you file. We cover consolidating with bad credit separately.
