Home Equity Line of Credit (HELOC): What It Is & How It Works

Updated 2026-09-05 · By Michael Chen, CPA

Learn what a Home Equity Line of Credit (HELOC) is, how it works, and key factors like credit score and lender requirements. A balanced guide for US borrowers.

A Home Equity Line of Credit (HELOC) is a revolving credit account secured by your home’s equity—the difference between your property’s current market value and what you still owe on your mortgage. In simple terms, a HELOC lets you borrow against your home’s value, similar to a credit card, but with a draw period (typically 5–10 years) during which you can access funds as needed, followed by a repayment period (often 10–20 years) when you must pay back the balance. This is general educational information, not financial advice; your personal situation may vary.

How a HELOC Works

A HELOC works like this: a lender approves you for a maximum credit limit based on your home equity, credit history, and debt-to-income ratio. During the draw period, you can borrow money up to that limit, make interest-only payments or begin paying down principal, and reuse the credit as you repay it. After the draw period ends, you enter the repayment phase, where you must repay the remaining balance (usually in fixed monthly installments). Because the loan is secured by your home, the lender may perform a hard inquiry on your credit report during the application. A soft inquiry might be used for prequalification.

  • Draw Period: Typically 5–10 years; borrow, repay, and re-borrow.
  • Repayment Period: Usually 10–20 years; fixed monthly payments.
  • Interest Rate: Variable rate tied to a prime index rate, meaning payments can change over time.
  • Credit Impact: Your credit utilization on a HELOC can affect your credit score, especially if you carry a high balance relative to your limit.

Key Requirements for a HELOC

Lenders evaluate several factors when deciding whether to approve a HELOC. While exact criteria vary, general guidelines include:

RequirementTypical Minimum
Credit Score620–680 (higher scores often get better terms)
Equity in HomeAt least 15–20% equity after the HELOC
Debt-to-Income RatioUsually below 43%–50%
Credit HistoryOn-time payments, low utilization, no recent bankruptcies

These are general estimates; always confirm with your specific lender. Your credit report and credit history are crucial—lenders will review both to assess your risk.

HELOC vs. Home Equity Loan: Key Differences

Both HELOCs and home equity loans let you tap into home equity, but they work differently. A home equity loan is a lump-sum payment with a fixed interest rate and fixed monthly payments for a set term. A HELOC offers a revolving line of credit with a variable rate and flexible draw periods. For example, if you need ongoing access to funds for renovations over several years, a HELOC may be more suitable. If you want a single sum for a one-time expense, a home equity loan might be better. This is general guidance; your choice depends on your financial goals.

How a HELOC Affects Your Credit

When you apply for a HELOC, the lender will likely perform a hard inquiry on your credit report, which can temporarily lower your credit score by a few points. After approval, your utilization on the HELOC is reported to credit bureaus—carrying a high balance relative to your credit limit can increase your utilization ratio, potentially lowering your score. On the other hand, making on-time payments and keeping your balance low can help build a positive credit history over time. Monitoring your credit report regularly is always a good practice.

Important Risks to Consider

Because a HELOC is secured by your home, failing to repay can lead to foreclosure—this is a serious risk. Variable rates mean your monthly payment can increase if interest rates rise. Some HELOCs also have balloon payments or require a lump-sum repayment at the end of the draw period. Always read the fine print with your lender.

Frequently Asked Questions

What credit score do I need to qualify for a HELOC?

Most lenders look for a credit score of at least 620 to 680, though some may accept lower scores with additional requirements. A higher score can improve your terms and interest rate. This is a general guideline; specific lender requirements may differ.

How much can I borrow with a HELOC?

Your borrowing limit is typically based on your home equity—often up to 85% of your home’s appraised value minus your current mortgage balance. Your lender will also review your credit history, debt-to-income ratio, and other financial factors.

Is a HELOC considered a second mortgage?

Yes, a HELOC is a form of second mortgage because it uses your home as collateral, just like your primary mortgage. It is secured by your property, so defaulting could lead to foreclosure.
