VA loans make homeownership more accessible for Veterans by minimizing costs like down payments and PMI. Still, some Veterans face hurdles qualifying on their own, whether due to lower credit scores or insufficient income.
That’s where co-borrowers and co-signers come into play, providing added financial stability and helping you secure the home you want.
This article breaks down the differences between co-borrowers and co-signers, explains how both roles work within the VA loan framework, and guides you through potential benefits, risks, and important steps.
With this knowledge, you’ll be empowered to make an informed decision about your homebuying journey.

What Is a VA Loan Co-Borrower?
A co-borrower on a VA loan is someone who shares full ownership of the home and equal legal responsibility for the mortgage. They are on the title, appear on the mortgage note, and are liable for repayment. Most commonly, a co-borrower is a spouse or another eligible Veteran.
- Full Ownership: Both names are on the deed. Co-borrowers jointly own the home and must coordinate on any refinancing or sale.
- Shared Liability: Each party is 100% responsible for on‑time payments. Missed payments damage both credit scores.
- Credit Use: Lenders may use the lower of two middle FICO scores or average them, depending on policy.
- Combined Income: Both incomes count toward your loan approval. This can help meet VA loan income requirements more easily.
What Is a VA Loan Co-Signer?
A co-signer agrees to repay the loan if you default but holds no ownership or title interest. Co-signers don’t live in the home and gain no equity, yet they assume the full risk if you can’t pay.
- Not on Title: Co-signers aren’t listed on the deed and don’t share ownership benefits.
- Full Legal Liability: The lender can pursue them for payment, collections, or foreclosure if the borrower defaults.
- Credit Strength: Most lenders prefer co-signers with excellent credit (700+ FICO) and low DTI.
- Family Preferred: Lenders typically approve parents or close relatives faster than friends or acquaintances.

Why Use a Co-Borrower or Co-Signer?
Adding a co‑borrower or co‑signer helps you overcome common VA loan hurdles like low income, high DTI, or limited credit.
- Higher Loan Limits: A combined monthly income of $6,000 can qualify you for a loan $150K higher than $3,000 alone. See how income affects VA loan income eligibility.
- Better Rates: A stronger average credit score can drop your interest rate by 0.5% or more, saving you thousands over the life of the loan.
- Lower DTI: A second income offsets existing debts, keeping your DTI under 41%—a common lender benchmark. Use our DTI ratio calculator to estimate your standing.
- Residual Income Boost: VA guidelines require enough income left after expenses. A co‑borrower increases your residual income buffer.
Who Can Be a VA Loan Co-Borrower?
The VA permits co‑borrowers in select categories, with spouses always allowed. Two eligible Veterans can combine entitlements for a higher loan limit. Some lenders also accept non‑Veteran partners, though this usually requires a significant down payment to cover the portion not guaranteed by the VA:
- Spouses: Always permitted. Their full income and credit profile are included in underwriting.
- Veterans: Two Vets may combine VA entitlements. This can unlock larger loan amounts—but also ties up both benefits until the loan is repaid or refinanced.
- Non‑Veteran Partners: Allowed by some lenders but often triggers a down payment on the unguaranteed portion. For a $400K loan split 50/50 with a non‑Vet, expect to pay about $50K down.

Who Can Be a VA Loan Co-Signer?
VA loan co‑signers are usually non‑occupant family members like parents, siblings, or adult children who have solid credit and reliable income. Friends or roommates are rarely accepted unless there’s a proven financial tie. Some borrowers also turn to trusted advisors or business partners, subject to lender approval.
- Parents, Siblings, Adult Children: Strong credit and steady income make them ideal co‑signers.
- Friends or Roommates: Rarely approved unless a deep financial connection can be demonstrated.
- Trusted Advisors: Some borrowers use trusted mentors or business partners—though lender acceptance varies.
Keep in mind that co‑signers do not use or affect your VA entitlement.
How Co-Borrowers and Co-Signers Help You Qualify
Co‑borrowers and co‑signers can make a powerful difference in VA loan approval. By increasing total household income, improving overall credit strength, lowering your debt‑to‑income (DTI) ratio, and helping meet the VA’s residual income requirements, they can help you qualify for larger loan amounts and better interest rates.
1. Boosting Income
Let’s say you earn $3,200/month and need $5,500/month to qualify. A spouse or Veteran friend earning $2,500/month can bridge the gap instantly—boosting your max loan from $275K to $450K.
2. Improving Credit
If your credit is 620 and your co‑borrower has a 750 score, you may qualify for better terms and rates. Some lenders average scores, others take the lowest middle—ask upfront.
3. Reducing DTI Ratio
More income and fewer debts lower your DTI ratio. This metric is central to approval—and a co‑borrower’s income may push you under key thresholds.
4. Meeting Residual Income
VA uses a formula based on family size and location. Add a second income and subtract minimal debts to exceed the required residual income amount.
Risks of Using a Co-Borrower or Co-Signer
Adding a co‑borrower or co‑signer can strengthen your VA loan application, but it also introduces serious financial and legal risks. These risks don’t just affect the primary borrower—they apply equally to everyone listed on the loan. Understanding the downsides helps you avoid costly surprises if your situation changes down the road.
- Joint Credit Damage: If the mortgage is paid late, every borrower’s credit report takes a hit. A single 30‑day late payment can lower FICO scores by 70 to 100 points. This impacts your ability to qualify for future loans, credit cards, or even certain jobs—especially for service members with security clearance.
- Entitlement Lock: When two eligible Veterans combine their VA loan entitlements, both benefits are tied to the loan. Until the mortgage is paid off, refinanced, or the property is sold and entitlement is restored, neither Veteran can reuse their benefit. This can limit future flexibility if either Veteran plans to buy again.
- No Equity for Co-Signers: Co‑signers often assume financial risk without receiving ownership benefits. Unless they’re named on the deed or title, they gain no equity, no share of appreciation, and no tax advantages. Yet they’re still legally responsible for the full mortgage if the borrower defaults.
- Legal Disputes: Unmarried co‑borrowers—such as friends, siblings, or dating partners—should create a written agreement outlining ownership percentages, exit terms, and decision‑making protocols. Without it, refinancing or selling can turn into legal battles. A real estate attorney can help draft a co‑ownership agreement that protects everyone involved.
VA Loan Rules for Co-Borrowers and Co-Signers
The VA sets core rules for occupancy, entitlement, and underwriting—but individual lenders may enforce stricter standards. Understanding these requirements is essential for structuring your application correctly and avoiding avoidable setbacks during the approval process.
- Occupancy Requirement: The primary Veteran borrower must intend to live in the home as their primary residence, usually within 60 days of closing. Co‑borrowers generally must also occupy the home. Co‑signers, however, are not required to live in the property—they simply guarantee the loan.
- Entitlement Limitations: Non‑Veteran co‑borrowers do not contribute to the VA loan guarantee. This means any part of the loan not covered by VA entitlement may require a down payment. For example, a $400,000 loan split with a non‑Veteran could require a $50,000 down payment to meet lender requirements.
- Credit Score Requirements: The VA itself doesn’t enforce a hard minimum credit score, but most lenders set their threshold around 620 FICO. Some may apply overlays—stricter rules on top of VA guidelines. You can learn more in our full article on VA loan credit score minimums.
- Residual Income Standards: Residual income is the amount left over each month after major expenses. It’s a core VA metric tied to family size and geographic region. Meeting this standard is non‑negotiable. You can check your regional income threshold in the VA’s underwriting manual.
Legal Considerations Before You Apply
If you’re buying with someone other than your spouse, it’s crucial to get legal clarity before applying. Even with family or close friends, financial partnerships can turn contentious without documented agreements in place.
- Document Ownership Shares: If multiple people are contributing financially or named on the mortgage, specify in writing who owns what portion of the property. This clarity can avoid confusion and legal conflict later—especially when refinancing or selling the home.
- Define Payment Responsibilities: Agree in advance who will pay what. Will payments be split 50/50? What happens if one person loses income or wants to stop contributing? Define roles clearly and put them in writing to prevent misunderstandings or financial strain.
- Plan for Future Exit Scenarios: Life situations change—someone may want to move, cash out, or buy solo later. Create a buyout clause or trigger for refinancing so that everyone knows what happens if one party wants out. These agreements reduce risk and preserve relationships.
- We recommend involving an attorney, especially for joint VA loans between unmarried individuals.

FAQs About VA Loan Co-Borrowers and Co-Signers
Can a non‑Veteran be a co‑borrower on a VA loan?
Yes, but only the Veteran’s portion of the loan is guaranteed by the VA. Most lenders will require a down payment to cover the non‑Veteran’s share of the loan risk.
Is the co‑signer legally responsible for the full loan?
Yes. A co‑signer is just as liable as the primary borrower. If the borrower defaults, the lender can pursue the co‑signer for the full balance.
Can I use a co‑borrower for a VA refinance?
Yes. If both parties were on the original loan, they can be included in a VA IRRRL refinance. For a cash‑out refinance, standard underwriting applies.
Does a co‑borrower impact the VA funding fee?
No. The funding fee is based only on the Veteran’s eligibility status and whether they are exempt due to disability or other factors.
Can a co‑signer live in the home?
Typically no. Co‑signers are not owners and are not expected to occupy the home. They exist solely to strengthen the application.
What happens if a co‑borrower dies?
Ownership and loan responsibility typically transfer to the surviving borrower. The deceased’s estate may still be involved depending on title structure.
Can I add a co‑borrower after closing?
No. Co‑borrowers must be added at the time of loan origination. Changes after closing require a refinance.
How does the VA calculate residual income for co‑borrowers?
VA lenders consider combined income minus total debts. Residual income requirements vary by region and family size.
What kind of credit score does a co‑signer need?
Lenders prefer co‑signers with scores of 680+. While the VA doesn’t set a minimum, most lenders have internal overlays.
How does a VA loan with a co‑borrower compare to a conventional loan?
VA loans offer no PMI, $0 down, and flexible credit—making them more affordable than conventional loans, even with a co‑borrower.
