HELOC & Your Credit Score: How a Home Equity Line of Credit Can Help or Hurt You

If you own a home, you've probably heard of a HELOC — a Home Equity Line of Credit. It's a revolving line of credit secured by your home's equity, and it can be a powerful financial tool. But before you apply, you need to understand exactly how a HELOC affects your credit score — for better and for worse.

What Happens to Your Credit When You Apply for a HELOC?

The moment you submit a HELOC application, the lender pulls a hard inquiry on your credit report. This temporarily lowers your score by a few points — typically 5 to 10 points — and stays on your report for two years. If you're shopping around with multiple lenders, try to do it within a 14-to-45-day window, as credit scoring models often treat multiple inquiries for the same type of loan as a single inquiry.

Once approved, the HELOC appears on your credit report as a new revolving account. This can initially lower your average account age, which may cause a small, temporary dip in your score. Don't panic — this is normal and recovers over time.

How a HELOC Can Actually Boost Your Credit Score

Here's the good news: a HELOC, used wisely, can be a credit-building asset. Because it's a revolving line of credit (similar to a credit card), it factors into your credit utilization ratio — the percentage of available revolving credit you're using. If you open a HELOC with a $50,000 limit and only use $5,000, your utilization on that account is just 10%, which is excellent.

Practical steps to use a HELOC to improve your credit: 1. Keep your balance low. Aim to use no more than 30% of your HELOC limit at any time — ideally under 10%. 2. Make on-time payments every month. Payment history is 35% of your FICO score. Even minimum payments count, but paying more reduces your balance faster. 3. Don't close it prematurely. Keeping the account open (even with a zero balance) adds to your available credit and can improve your utilization ratio. 4. Avoid maxing it out. A maxed-out HELOC signals financial stress to lenders and can significantly hurt your score.

The Risks: How a HELOC Can Hurt Your Credit

A HELOC is secured by your home — meaning if you default, you could lose it. Beyond that serious risk, here's how it can damage your credit:

• High utilization: Using a large portion of your HELOC limit raises your utilization ratio and lowers your score.
• Missed payments: Late or missed payments are reported to the bureaus and can drop your score significantly.
• Closing the account: If you close a HELOC, you lose that available credit, which can spike your utilization ratio overnight.

The Bottom Line

A HELOC is neither inherently good nor bad for your credit — it's all about how you manage it. Used strategically, it can diversify your credit mix, lower your utilization, and demonstrate responsible credit management. Used carelessly, it can drag your score down and put your most valuable asset at risk.

Before opening a HELOC, make sure your credit score is in good shape (most lenders want 620+, but 700+ gets you the best rates), your debt-to-income ratio is healthy, and you have a clear plan for how you'll use and repay the funds.

Your action step today: Check your home equity and current credit score. If you're considering a HELOC, get pre-qualified with at least two lenders to compare rates — and remember, smart borrowing is the foundation of lasting credit health.
