Most mainstream banks won't refinance a car loan where you owe more than the car is worth, but credit unions, online lenders, and some subprime auto lenders will consider it

An upside down loan (also called being "underwater") means the amount you owe exceeds what the vehicle is worth. A bank that refinances you takes on that gap as risk—if you stop paying and they repossess the car, they sell it for less than the loan balance and absorb the loss. Most large banks like Chase, Bank of America, and Wells Fargo decline these loans outright. But credit unions, online lenders specializing in bad credit, and some captive finance companies (like Ford Credit or GM Financial) will refinance them, though the terms and rates reflect the higher risk.

The lenders most likely to work with you fall into three categories: credit unions that serve your area or profession, online lenders that advertise "upside down auto refinancing" or "negative equity refinancing," and the manufacturer's own finance arm if you own that brand. Each has different underwriting rules, so rejection from one does not mean rejection from all.

Key Takeaways

  • Credit unions typically offer the best rates for upside down refinancing because they are member-owned and can take longer-term loans; start with your employer's credit union or a community credit union in your state.
  • Online lenders like LendingClub, Upgrade, and LightStream can refinance negative equity loans, though rates are higher than credit unions and depend on your credit score and income.
  • Captive finance companies (Ford Credit, GM Financial, Toyota Financial) will sometimes refinance their own loans with negative equity if you have made payments on time.
  • Expect a higher interest rate than you would for a standard refinance because the lender is absorbing the gap between what you owe and what the car is worth.
  • Some lenders will roll the negative equity into a longer loan term to lower your monthly payment, which costs more in total interest but improves cash flow when ready.

Credit Unions: The most common source for upside down refinancing

Credit unions refinance upside down car loans more often than banks because they operate as nonprofits owned by their members. They can approve longer loan terms (72 to 84 months is common) and accept lower profit margins, which makes negative equity loans manageable. Start by checking whether your employer, union, or professional association runs a credit union—membership is often free or very cheap. If not, search for community credit unions in your state using the CO-OP Network or Shared Branch locator on the Credit Union National Association website.

When you contact a credit union, ask directly whether they refinance upside down loans and what their current rate is for your credit score range. Many credit unions will give you a rate quote over the phone without a hard credit pull. Bring your current loan documents (the promissory note or loan statement showing the balance) and the vehicle's current market value from Kelley Blue Book or NADA Guides. Credit unions often approve within 3 to 5 business days if your income and employment check out.

Online lenders and fintech platforms

Online lenders like LendingClub, Upgrade, and LightStream market themselves as willing to refinance negative equity loans, and they can move faster than traditional banks—some offer same-day or next-day funding. However, their rates are typically 2 to 4 percentage points higher than credit unions for the same credit score, because they carry more risk and have higher operating costs. Check their websites for "upside down auto refinance" or "negative equity" language; if they advertise it, they have already decided to take that risk.

The process process is entirely online. You will enter your loan details, vehicle information, and income. The lender pulls your credit report and may verify employment. Approval usually takes 24 to 48 hours. If approved, the lender pays off your existing loan and sends you new loan documents. Read the terms carefully: some online lenders charge origination fees (1 to 3 percent of the loan amount) or prepayment penalties, which add to your cost.

Captive finance companies: Your current lender's parent company

If you financed your car through Ford Credit, GM Financial, Toyota Financial Services, or another manufacturer's finance arm, that company may refinance your existing loan even if you are upside down—especially if you have made all payments on time. These lenders have a relationship with you already and know your payment history. Call the customer service number on your loan statement and ask whether they offer "negative equity refinancing" or "upside down refinancing" on your account.

Captive finance companies rarely advertise this option publicly, so many borrowers do not know to ask. The approval process is faster than explore to a new lender because they already have your full financial picture. However, their rates are not always competitive; they may offer you a lower rate than you currently have, but not as low as a credit union would. The trade-off is speed and certainty—if you are approved, funding can happen within days.

What to expect: rates, terms, and costs

An upside down refinance will cost more than a standard refinance. If your credit score is 650 to 700, expect rates between 8 and 14 percent, depending on the lender and how far underwater you are. A credit union might offer 8 to 10 percent; an online lender might offer 11 to 14 percent. If your score is below 650, rates climb further. The lender is pricing in the risk that you walk away or default, leaving them with a car worth less than the loan balance.

Lenders typically extend the loan term to 72 or 84 months to keep your monthly payment manageable. This lowers your payment but increases the total interest you pay over the life of the loan. For example, rolling $5,000 of negative equity into a 72-month loan at 10 percent costs you roughly $1,200 more in interest than a 60-month loan at the same rate. Ask the lender for an amortization schedule so you can see the total cost before you sign.

Some lenders charge origination fees, documentation fees, or title transfer fees. These are separate from the interest rate and add to your out-of-pocket cost. Online lenders are more likely to charge these than credit unions. Ask for the total cost of the loan, not just the monthly payment.

How to improve your chances of approval

Lenders want to see stable income and a history of on-time payments. Before you explore, pull your credit report from AnnualCreditReport.com and check for errors or late payments. If you have missed payments on your current car loan, wait until you have made at least three months of on-time payments before refinancing; lenders view recent delinquency as a red flag. If your income is irregular or you are self-employed, gather recent tax returns and bank statements to show income stability.

The smaller the gap between what you owe and what the car is worth, the easier approval becomes. If you are $8,000 underwater on a $15,000 car, that is a harder sell than being $2,000 underwater. If you have the cash to pay down the negative equity before refinancing, doing so dramatically improves your approval odds and lowers your interest rate. Even a $1,000 or $2,000 payment toward the principal makes a difference.

explore to multiple lenders within a two-week window. Multiple credit inquiries from auto lenders within 14 days count as a single inquiry on your credit score, so you will not be penalized for shopping around. Collect rate quotes from at least three lenders—a credit union, an online lender, and your current lender if it is a captive finance company—before you decide.

When refinancing an upside down loan does not make sense

Refinancing costs money and extends your debt. If you are only slightly underwater (less than $1,000) and your current rate is already low (below 6 percent), refinancing may not save you enough to justify the fees and extra interest. Calculate the total cost: take the new monthly payment minus the old monthly payment, multiply by the number of months, and subtract any fees. If the savings are less than $500 over the life of the loan, refinancing is probably not worth it.

If you are planning to sell or trade in the car within the next year or two, refinancing locks you into a longer obligation. You will still owe the negative equity even after you sell the vehicle, and you will be making payments on a car you no longer own. In this case, focus on paying down the principal as fast as you can rather than refinancing.

Frequently Asked Questions

Can I refinance if I have missed payments on my current loan?

Most lenders will decline you if you have missed a payment in the last 12 months. If you missed one payment, wait at least three months of on-time payments before explore. If you have multiple missed payments or a repossession, refinancing becomes much harder; focus on rebuilding your payment history first.

What if no lender will refinance me?

If you are declined everywhere, your options are to pay down the negative equity with cash or a personal loan, wait and build your credit score, or keep making payments on your current loan. Some lenders will reconsider you after six months if your credit improves or your income increases.

Will refinancing hurt my credit score?

The hard credit inquiries will lower your score by a few points temporarily, but the impact fades within a few months. If you are approved and take out the new loan, your score may dip slightly at first because you now have a new account and a higher total debt balance. Over time, on-time payments on the new loan will rebuild your score.

Can I refinance if the car has high mileage or mechanical problems?

Lenders care about your payment history and income, not the car's condition. However, if the car is worth very little because of high mileage or damage, the negative equity gap widens, making approval harder. Get a current market value from Kelley Blue Book or NADA Guides to know how far underwater you are before you explore.

What is the difference between refinancing and a personal loan?

A personal loan is unsecured (the lender has no claim to the car), so rates are higher but you are not locked into the vehicle. An auto refinance is secured by the car, so rates are lower but the lender can repossess if you default. For upside down loans, auto refinancing is usually cheaper than a personal loan, even with the higher rate.
