Can You Get a HELOC with a Cosigner? What Lenders Actually Allow

Getting a HELOC when your credit or income isn't quite there is frustrating. You might be thinking: "Can I just add a cosigner like I did for my car loan?"

Here's the complicated truth: Yes and no. Most HELOC lenders don't accept traditional cosigners—they require co-borrowers instead. And that distinction matters more than you might think.

The Cosigner vs Co-Borrower Confusion

Let's clear up terminology that trips up most borrowers:

Cosigner: Signs for the debt but isn't on the property title. They guarantee repayment but don't own the home.

Co-borrower (Co-applicant): Signs for the debt AND is on the property title. They're part-owners of the home.

Here's why this matters for HELOCs: A HELOC is a secured debt. Your home is the collateral. If you don't repay, the lender can foreclose.

Most lenders require co-borrowers—not just cosigners—because only someone on the title can legally offer the property as collateral. A cosigner who doesn't own your home can't pledge it as security.

Why Lenders Prefer Co-Borrowers

Think about it from the lender's perspective:

1. Collateral clarity. If both borrowers are on the title, there's no question about who owns the collateral.
2. Foreclosure rights. Lenders need clear legal authority to foreclose if necessary.
3. Liability alignment. Co-borrowers have skin in the game—they own the home too.

Some lenders will allow a non-title cosigner, but they're the exception. And even then, they'll still pull the cosigner's credit and include their income and debts in the qualification.

Cosigner/Co-Borrower Requirements

If you're adding someone to your HELOC application, here's what lenders typically require of them:

The co-borrower's income and debts get combined with yours. This helps if they have high income and low debt. It hurts if they have existing debt obligations.

Which Lenders Allow What

Lender policies vary significantly:

Bottom line: If you need help qualifying, expect most lenders to require that person to be on your property title.

The Risks Your Co-Borrower Faces

Before asking someone to co-sign or co-borrow, they need to understand what they're agreeing to:

1. Their Home Is at Risk

If your co-borrower goes on title and you default, they could lose their ownership interest in a foreclosure.

2. Full Liability for the Debt

Co-borrowers are 100% responsible for the entire balance—not just half. If you stop paying, the lender can pursue them for everything.

3. Credit Score Impact

Every payment (and missed payment) appears on their credit report. Late payments hurt both of you.

4. Reduced Borrowing Capacity

The HELOC counts in their DTI for future loans. This could affect their ability to get a mortgage, car loan, or other credit.

Alternatives If You Can't Qualify Solo

If adding a co-borrower isn't feasible, consider these options:

Build Your Credit First

A few months of credit improvement can make a significant difference:

• Pay down credit card balances below 30% utilization
• Dispute any errors on your credit report
• Avoid opening new accounts

Timeline: 3-6 months to see meaningful improvement

Apply for a Smaller Amount

Lower loan amounts are easier to qualify for. If you need $80,000 but can only qualify for $50,000, you might:

• Start with the lower amount
• Request a credit line increase after 12 months of on-time payments

Consider a Home Equity Loan Instead

Fixed-rate home equity loans sometimes have slightly different underwriting. You might qualify for one even if a HELOC is out of reach.

Try Different Lenders

HELOC requirements vary. Credit unions often have more flexible qualification criteria than big banks. Shop around before giving up.

Frequently Asked Questions

Can my spouse cosign if they're not on the title?

In most states, your spouse may need to sign certain documents (like a deed of trust) even if they're not on title. But for HELOC qualification purposes, they'd typically need to be added to the title to count as a co-borrower.

Can my parent cosign for my HELOC?

Only if they're willing to be added to your property title. A parent signing as a traditional cosigner (not on title) is rarely accepted for HELOCs.

Will a cosigner's income help me qualify?

Yes—if they're accepted as a co-borrower. Their income gets added to yours when calculating DTI. But their debts count too.

What credit score does a cosigner need?

Most lenders want 680-720+ for co-borrowers. The higher their score, the better terms you may both get.

The Bottom Line

The word "cosigner" means something different for HELOCs than it does for unsecured debt like auto loans. Most HELOC lenders require co-borrowers—people who are on your property title—not just someone willing to guarantee the debt.

Before asking someone to help you qualify, make sure they understand:

• They'll likely need to be added to your property title
• They're accepting full responsibility for the debt
• Their credit and borrowing capacity will be affected

If that's not workable, focus on improving your own qualifications or finding a lender with more flexible terms.
