Cosigner Helps — But Isn't Always Needed
When a Cosigner Is Required vs Optional
Most of our customers get approved without a cosigner. A cosigner is a tool — one that helps in specific situations, not a standard hurdle every borrower must clear.
⚠ When a cosigner may be requested
- •Credit score below 450
- •Income is borderline for the payment
- •Very recent bankruptcy (less than 6 months discharged)
- •First-time buyer with no credit history and limited income
✓ When a cosigner is NOT needed
- •Stable income above $2,500/month
- •Credit score 500 or higher
- •6 or more months of employment
- •Adequate down payment toward the vehicle
These are general thresholds. Individual lenders vary — which is why submitting through a dealership network of 20+ lenders gives you far more chances at a single-applicant approval than applying to one bank alone.
How a Cosigner Improves Your Deal
Even if you can get approved alone, a cosigner can improve your terms. Lenders evaluate risk — and a stronger combined profile means less risk for them, which translates directly into better outcomes for you.
Lower interest rate
If your cosigner has a credit score of 700 or higher, the lender may place you in a better rate tier — sometimes dropping a full tier. On a $20,000 loan over 72 months, moving from 19.9% to 14.9% saves approximately $4,200 in total interest.
Smaller down payment requirement
A borderline application may require a $3,000 down payment to get approved. Add a cosigner with solid income and that requirement may disappear entirely — freeing up cash you were planning to put toward the vehicle.
Access to newer or more expensive vehicles
Some lenders restrict vehicle age or value for higher-risk single applicants. A cosigner can widen those limits — opening up 2020 vs 2017, or $28,000 vs $18,000 approved amounts.
Longer term options
Subprime-only approvals sometimes cap at 60-month terms. With a cosigner, 72 or 84 months may become available — lowering your monthly payment even if the total cost is higher.
The lender evaluates the stronger of the two profiles — your income and your cosigner's credit combine to produce a blended risk picture that is better than either applicant alone.
Cosigner Responsibilities — What They Need to Know
Be upfront with your cosigner: this is a real financial commitment. It is not a formality. The cosigner is equally responsible for the loan, and the lender does not distinguish between primary and co-applicant when things go wrong.
They are equally responsible for the loan
If you miss payments, the lender can pursue the cosigner for the balance. Their credit score takes the same hit yours does — every missed payment, every collection action, appears on both credit reports simultaneously.
The loan appears on their credit report
From the day the loan funds, it shows up on the cosigner's credit report as an active obligation. Lenders will count this debt when the cosigner applies for anything else — a mortgage, a credit card, their own car loan. This affects their debt-to-income ratio.
Default means they are on the hook for the full balance
If the vehicle is repossessed and sells for $12,000 but $17,000 is still owed, the cosigner is liable for the $5,000 deficiency. This is not hypothetical — it is a clause in every loan contract.
On-time payments benefit them too
The flip side: if you make every payment on time, the cosigner's credit score also benefits. A 12-24 month track record of on-time payments adds positive history to both files. Used correctly, the loan improves the cosigner's credit alongside yours.
The path to releasing your cosigner
Once the loan is paid off or refinanced in your name only, the cosigner is released from all obligations. Many customers use the car loan to build credit for 12-24 months, then refinance solo — getting a lower rate and freeing their cosigner at the same time. It is a common and realistic exit strategy.
Alternatives to Having a Cosigner
No cosigner available? That doesn't close the door. Several levers can strengthen a single-applicant application enough to get approved without bringing anyone else into the deal.
Larger down payment
A down payment of $2,000-$3,000 signals financial commitment to the lender and directly reduces the loan-to-value ratio — one of the primary risk measures. A borderline application with a strong down payment often crosses the threshold without needing a cosigner. Even $1,000 can make a meaningful difference.
Choose a less expensive vehicle
A smaller loan amount is easier for a single applicant to qualify for. If you are approved for $18,000 solo but need a cosigner at $25,000 — and a reliable vehicle exists in your approved range — dropping down is often the cleanest path forward.
Demonstrate strong employment history
Two or more years at the same employer is viewed very favorably, even with a lower credit score. If you have job tenure working in your favour, make sure your application reflects it fully — exact start dates, current pay rate, and employment type all matter.
Show additional income sources
Part-time jobs, freelance income, rental income, and government benefits all count — as long as you can document them. A pay stub from a second job or a screenshot of consistent e-transfer deposits adds to your qualifying income and strengthens your debt-to-income ratio.
Apply through a dealership with 20+ lenders
This is the single biggest factor for single-applicant approvals. Applying to one bank gives you one answer. Submitting through our network reaches 20+ lenders simultaneously — including subprime specialists who focus exclusively on single-applicant deals that mainstream banks decline. More lenders means more chances.

Frequently Asked Questions
Do I always need a cosigner for a car loan with bad credit?
No. Many of our customers with credit scores in the 400-600 range get approved single-applicant. It depends on income, employment stability, and down payment. A cosigner is one tool — not a requirement.
Who can be a cosigner for a car loan?
Any adult with a valid ID, stable income, and willingness to share responsibility. Typically a parent, spouse, sibling, or close friend. They do not need perfect credit — just better credit or income than the primary applicant.
Does being a cosigner affect their credit score?
Yes. The loan appears on their credit report. On-time payments help their score; missed payments hurt it. They should understand this before agreeing — it is a real financial commitment, not a formality.
Can I remove the cosigner later?
Yes, through refinancing. After 12-24 months of on-time payments, your credit may improve enough to refinance the loan in your name only, releasing the cosigner from all obligations.
What if my cosigner also has bad credit?
Two subprime applicants can still strengthen each other's application. Combined income may meet lender thresholds even if neither qualifies alone. We evaluate the full picture — income, stability, and down payment all factor in.
Does the cosigner need to come to the dealership?
No. We send them a secure online application link. They complete it from anywhere in about 2 minutes — no trip to the dealership required.
