HELOC Requirements: Credit, Equity and Income Rules

To qualify for a HELOC you generally need a credit score of 620 or higher, at least 15 to 20 percent equity in your home, a debt-to-income ratio of 43 to 50 percent or lower, steady verifiable income, and a qualifying property with an appraisal and homeowner's insurance. Lenders weigh all five together — strength in one area can partly offset weakness in another, but no single factor carries an application alone.

Credit Score Requirements

Your credit score is the lender's quickest read on how reliably you repay debt, and it directly affects both approval and pricing. Many lenders set 620 as a typical minimum for a HELOC. Approval at 620 is possible but not guaranteed, and the terms reflect the added risk: a higher margin over the index, which means a higher rate, and possibly a lower credit limit.

Scores of 680 and above open meaningfully better terms — lower margins, larger limits, and access to more lenders. At 740 and above, borrowers generally see the best pricing a lender offers. If your score sits just below a threshold, even a small improvement can change your rate: paying down credit card balances to lower your utilization and ensuring every payment is on time for several months are the two fastest levers most borrowers have.

Note that each lender sets its own minimums and pricing tiers, so a 640 score that one bank declines might be workable at a credit union with different guidelines. Comparing lenders matters as much as improving your score. See our step-by-step guide to how to get a HELOC for how to shop lenders effectively.

Equity Requirements and CLTV

Equity is the foundation of a HELOC — it is the collateral, so lenders protect it carefully. Most lenders require you to keep at least 15 to 20 percent of your home's value as equity after the line is in place. They express this as a maximum combined loan-to-value (CLTV) ratio of 80 to 85 percent: your mortgage balance plus your full HELOC credit limit, divided by your home's appraised value, must stay at or below that cap.

That cap determines your maximum line with a simple formula:

Maximum line ≈ (home value × maximum CLTV) − mortgage balance

Worked example: how much equity do you need?

Take a home appraised at $400,000 with a $250,000 mortgage balance, at a lender with an 80 percent CLTV cap:

$400,000 × 0.80 = $320,000 maximum secured debt
$320,000 − $250,000 mortgage = $70,000 maximum HELOC

The homeowner keeps $80,000 of equity untouched (20 percent of the home's value), satisfying the lender's cushion. If the same lender allowed 85 percent CLTV, the line could reach $90,000. A low appraisal shrinks the line the same way a high mortgage balance does — both reduce the equity available above the cap.

All figures are estimates for illustration only — not financial advice. Your actual terms will differ; confirm with your lender.

Borrowers sometimes ask whether they can get a HELOC with little equity. A few lenders go above 85 percent CLTV, but those products are rarer, carry higher rates, and often come with mortgage insurance-like costs. For most borrowers, 15 to 20 percent equity is the realistic entry point.

Debt-to-Income Ratio (DTI)

Your debt-to-income ratio measures your total monthly debt payments against your gross monthly income. Lenders typically want a DTI of 43 to 50 percent or lower for a HELOC. The calculation includes your mortgage payment (principal, interest, taxes, and insurance), the projected payment on the new HELOC, car loans, student loans, credit card minimums, and any other recurring debts.

For example, with $8,000 in gross monthly income and $3,600 in total monthly debts including the projected HELOC payment, your DTI is 45 percent — within most lenders' limits. At $4,400 in debts, the same income gives a 55 percent DTI, which most lenders would decline. Paying off a car loan or a credit card balance before applying is often the fastest way to bring a borderline DTI into qualifying range.

Income and Employment Requirements

Lenders must verify you can afford the payments, so steady, documentable income is a core requirement. Acceptable income generally includes wages and salaries, self-employment earnings, retirement and pension income, Social Security, and consistent investment income. What matters is that it is stable and provable with documents: pay stubs, W-2s or 1099s, tax returns, and bank statements.

Self-employed borrowers face closer scrutiny and usually need one to two years of tax returns plus profit-and-loss statements, since lenders average variable income rather than taking a single good year at face value. Borrowers between jobs, with large unexplained deposits, or with income the lender cannot document should expect delays or denials until the paper trail is clean. There is no way around this requirement with most mainstream lenders — unverifiable income is one of the most common denial reasons.

Property Requirements

The home itself must qualify as collateral. Lenders generally require:

• A qualifying property type. Most HELOCs are offered on primary residences — single-family homes, and often condos and townhomes. Second homes and investment properties are harder: fewer lenders offer them, and those that do usually demand higher credit scores, lower CLTV caps, and higher rates.
• A current appraisal or valuation. The lender needs a credible current value to compute your equity. This may be a full in-person appraisal, a drive-by appraisal, or an automated valuation, depending on the lender and loan size.
• Adequate condition. A home in serious disrepair may fail to qualify, since the lender's collateral must hold its value. Major structural issues or safety hazards found during appraisal can stall or kill an application.
• Homeowner's insurance. Lenders require the property to be insured for at least the loan amounts, and in flood zones they typically require flood insurance as well.
• Clear title. Liens, judgments, or ownership disputes uncovered in the title search must be resolved before closing.

Common Disqualifiers

Even borrowers who meet the headline numbers get denied for avoidable reasons. Watch for these: a recent bankruptcy or foreclosure still inside the lender's waiting period; a credit report with active disputes, which many lenders require resolved before underwriting; an appraisal that comes in below expectations; unpermitted additions or zoning issues that cloud the property's value; and applying for a line far larger than your income can support, which inflates the projected payment in the DTI calculation. If you are denied, the lender's adverse action notice names the specific reasons — treat it as a repair checklist, not a final verdict.

How to Improve Your Odds Before Applying

Give yourself two to three months of preparation and work this checklist in order of impact. First, pull your credit reports and dispute errors — this is free and sometimes moves your score within weeks. Second, pay down revolving balances to get credit utilization under 30 percent, ideally under 10 percent. Third, avoid opening new credit or making large purchases on credit before applying. Fourth, pay down installment debts that inflate your DTI. Fifth, gather every document on the application checklist so underwriting never waits on you. Finally, get a realistic sense of your home's value from recent comparable sales so the appraisal holds no surprises. Borrowers who do this groundwork close faster and on better terms.
