Yes, a Home Equity Line of Credit (HELOC) can affect your credit score both positively and negatively. Initially, applying for a HELOC will cause a small, temporary drop in your score due to a hard inquiry, but responsible use over time can actually improve your credit profile.
How It Affects Your Score (Step-by-Step Breakdown)
UpstartWhat Happens Immediately: The Hard Inquiry
When you apply for a HELOC, the lender will perform a hard credit check to review your credit history and determine your eligibility. This hard inquiry will be recorded on your credit report and typically causes a temporary drop of 5 to 10 points in your FICO® Score. The inquiry remains on your credit report for two years, but its impact on your score usually fades after about six months. If you are rate shopping among multiple lenders, FICO scoring models generally treat multiple mortgage-related inquiries within a 14- to 45-day window as a single inquiry, minimizing the negative impact.
Short-Term Impact: New Account and Credit Age
Once your HELOC is approved and opened, it appears as a new tradeline on your credit report. This new account lowers the average age of your credit history, which accounts for 15% of your FICO® Score. A lower average credit age can cause a slight dip in your score. However, adding a HELOC also increases your total available credit. Depending on how the lender reports the HELOC (as a revolving account or an installment loan), it may affect your credit utilization ratio. Interestingly, FICO® Scores generally exclude HELOCs from revolving credit utilization calculations, meaning a high balance won't necessarily tank your FICO score the way maxing out a credit card would. However, VantageScore® models may factor HELOC utilization into their calculations.
Long-Term Impact: Payment History and Credit Mix
In the long run, a HELOC can be a powerful tool for building a stronger credit profile. Payment history is the most significant factor in your credit score, making up 35% of the total. Consistently making on-time payments on your HELOC demonstrates financial responsibility and will steadily improve your score over time. Additionally, a HELOC can improve your "credit mix" (which accounts for 10% of your score) by adding a different type of secured debt to your profile, especially if you primarily have unsecured debt like credit cards. If you use your HELOC to consolidate and pay off high-interest credit card debt, you can significantly lower your revolving credit utilization, leading to a substantial boost in your credit score.
Impact Table (Timeline × Impact Type)
| Timeline | Action | Credit Score Impact | Why It Happens |
|---|---|---|---|
| Immediate | Submitting an application | -5 to -10 points | Lender performs a hard credit inquiry. |
| Short-Term (1-3 months) | Opening the account | Slight decrease | Lowers the average age of your credit accounts. |
| Ongoing | Making on-time payments | Positive increase | Builds a strong payment history (35% of FICO score). |
| Ongoing | Missing a payment (30+ days late) | Significant drop | Late payments severely damage your credit profile. |
| Strategic | Paying off credit cards with HELOC | Significant increase | Lowers revolving credit utilization ratio. |
| Long-Term | Closing the HELOC | Neutral to Slight Decrease | May reduce credit mix or available credit (depending on scoring model). |
How to Minimize Negative Impact
While some negative impact is unavoidable when applying for new credit, you can take strategic steps to protect your score:
- Shop for Rates Within a Short Window: To minimize the impact of hard inquiries, complete all your HELOC applications within a 14- to 45-day period. Credit scoring models will group these inquiries together and treat them as a single event.
- Look for Prequalification Options: Some lenders offer prequalification using a soft credit check. This allows you to see estimated rates and your likelihood of approval without any impact on your credit score.
- Keep Your Balance Manageable: Even though FICO® may not count HELOC utilization, other scoring models might. Borrow only what you need and have a clear plan for repayment to avoid becoming overextended.
- Set Up Automatic Payments: Payment history is the most critical factor in your credit score. Set up autopay to ensure you never miss a payment, as a payment that is 30 days late can cause a severe drop in your score.
- Don't Close Old Accounts: When you open a new HELOC, keep your older, zero-balance credit cards open. This helps maintain a longer average credit age and a lower overall credit utilization ratio.
