Qualifying
What is the minimum credit score for a HELOC?
Most lenders require a minimum credit score of 620 to qualify for a HELOC, though many competitive lenders set the practical floor at 680–700 for their best rates. A higher score unlocks a lower margin above the Prime Rate and a higher credit limit. Your score is one of three key factors — equity and income matter just as much.
The full picture
A Home Equity Line of Credit (HELOC) is a revolving line of credit secured by your home's equity. Because your home is the collateral, the CFPB explains that missed HELOC payments can result in foreclosure — so lenders underwrite HELOCs carefully, looking at credit, equity, and income together. Credit score is the entry ticket, but it's not the only gate.
Credit score requirements: what lenders typically set
Lenders typically require a minimum FICO score of 620 to qualify for a HELOC, the same floor used for conventional mortgages. In practice, most lenders set their best-rate tier at 700 or higher. Borrowers in the 620–679 range may qualify but will often face a higher rate margin above the Prime Rate — sometimes 1%–2% more than a borrower at 720+. Scores below 620 generally disqualify applicants from most HELOC programs; some lenders have higher minimums (660 or 680) as a matter of policy.
- 620–659: Entry-level eligibility at some lenders — higher rate margins, stricter equity requirements.
- 660–699: Mid-tier approval range — standard terms, some rate premium above Prime.
- 700–719: Competitive range — most lenders offer standard pricing.
- 720+: Best available rate margin; maximum credit line access at most lenders.
The equity requirement: combined LTV matters as much as score
Credit score alone won't get you a HELOC — you also need equity. Lenders use Combined Loan-to-Value (CLTV), which adds your first mortgage balance and the new HELOC credit limit, then divides by the home's appraised value. Most lenders cap CLTV at 80%–85%. If your home is worth $400,000 and you owe $300,000 on your mortgage (75% LTV), a lender capping CLTV at 85% would allow a HELOC credit line up to $40,000. The loan-to-value ratio determines how much equity is available — track it before applying.
Income and DTI: the third pillar
HELOCs are second mortgages, and lenders verify that your total debt load — first mortgage, HELOC, plus all other monthly debts — stays within their DTI limits. A back-end DTI below 43% is the general standard for HELOC approval, consistent with qualified mortgage guidelines per the CFPB. Self-employed borrowers will need two years of tax returns; W-2 employees need recent pay stubs and W-2s.
How your credit score affects your HELOC rate
Most HELOCs are variable-rate products priced as Prime Rate plus a lender margin. The margin — typically 0%–2% depending on your creditworthiness — is where your score has a direct dollar impact. With Prime at 6.75% (as of August 2026 per the Federal Reserve H.15 release), a borrower at 720+ might receive Prime + 0.5% = 7.25%, while a borrower at 640 might receive Prime + 2.0% = 8.75%. On a $50,000 balance drawn over a full year, that 1.5% difference is $750 annually. Verify current Prime Rate before modeling your costs. Not every HELOC-adjacent lender uses this floating structure — see our review of the Figure Home Equity Loan, which prices with a fixed APR set at funding instead.
Your home is at risk — qualify carefully
A HELOC is secured by your home. Defaulting on a HELOC can result in foreclosure even if your first mortgage is current. Borrow against home equity only when you have stable income and a clear repayment plan.

Key takeaways
- Most lenders require a minimum 620 credit score for a HELOC; 700+ unlocks the best rate tiers.
- CLTV (first mortgage + HELOC ÷ home value) is capped at 80%–85% at most lenders — equity limits access more than score at high LTVs.
- Your score determines the rate margin above Prime — a 720+ score may save hundreds of dollars annually vs. a 640 score on the same balance.
- Back-end DTI below 43% is the standard income/debt threshold for HELOC qualification.
- Your home is collateral — qualify conservatively, not at the maximum your score permits.
Frequently asked questions
Can I get a HELOC with a 620 credit score?
Often yes — 620 is the minimum most lenders use, the same floor as conventional mortgages. But at 620–659 you'll typically face a higher rate margin above Prime and stricter equity requirements than a borrower in the 700+ range, so it's worth shopping multiple lenders.
What credit score do I need for the best HELOC rate?
700 or higher puts you in most lenders' competitive pricing tier, and 720+ typically unlocks the best available rate margin and maximum credit line access. The gap between a 640 score and a 720+ score can be worth hundreds of dollars a year in interest on the same balance.
Does a good credit score guarantee HELOC approval?
No — credit score is only one of three pillars lenders evaluate. You also need sufficient home equity (lenders cap combined loan-to-value at 80%–85%) and income that keeps your back-end debt-to-income ratio below roughly 43%. A high score with too little equity or too much existing debt still won't qualify.
How much equity do I need for a HELOC alongside my credit score?
Lenders use combined loan-to-value (CLTV): your first mortgage balance plus the new HELOC limit, divided by your home's appraised value. Most cap CLTV at 80%–85%. On a $400,000 home with a $300,000 mortgage balance (75% LTV), an 85% CLTV cap leaves room for roughly a $40,000 HELOC line.
Will a lower credit score cost me money even if I still qualify for a HELOC?
Yes. HELOCs are variable-rate products priced as Prime plus a lender margin, and that margin is where your score has a direct dollar impact — often a 1.5-percentage-point difference between a 720+ borrower and a 640 borrower, which adds up to hundreds of dollars a year on a typical drawn balance.
