If you have paid down your mortgage or your home has gained value, you may be sitting on a powerful source of low-cost borrowing. A home equity line of credit, or HELOC, lets you tap that equity as you need it for home renovations, large expenses, or paying off higher-interest debt. Because it is secured by your home, a HELOC usually carries a lower rate than credit cards or personal loans.
In this guide, you will learn how a HELOC works, how much you can borrow, how to qualify, and the steps to get one with the best terms.
What Is a Home Equity Line of Credit?
A HELOC is a revolving line of credit secured by your home. It works much like a credit card: you get a credit limit, borrow what you need, repay it, and borrow again. You only pay interest on the amount you actually use.
The Two Phases of a HELOC
- Draw period: Usually around 10 years. You can borrow freely, and many lenders allow interest-only payments during this time.
- Repayment period: Often 10 to 20 years. You can no longer borrow, and you repay both principal and interest, so monthly payments usually rise.
Most HELOCs have variable interest rates tied to the prime rate, so your payment can change as rates move. Some lenders let you lock a portion of your balance at a fixed rate.
HELOC vs Home Equity Loan vs Cash-Out Refinance
- HELOC: Flexible, revolving credit with a variable rate. Best for ongoing or uncertain costs, like a remodel paid in stages.
- Home equity loan: A lump sum with a fixed rate and fixed payments. Best when you know the exact amount you need.
- Cash-out refinance: Replaces your current mortgage with a larger one and pays you the difference. Can make sense when new mortgage rates are lower than your existing rate.
How Much Can You Borrow With a HELOC?
Lenders typically let you borrow up to 80% to 85% of your home’s value, minus what you still owe on your mortgage. This is called the combined loan-to-value ratio, or CLTV.
Example: Your home is worth $400,000 and you owe $220,000 on your mortgage.
- 85% of $400,000 = $340,000
- $340,000 − $220,000 = $120,000 potential HELOC limit
Your actual limit depends on your credit score, income, and the lender’s guidelines.
HELOC Requirements
While requirements vary, most lenders look for:
- At least 15% to 20% equity in your home
- A credit score of around 680 or higher, with the best rates often reserved for 740+
- A debt-to-income ratio generally at or below 43%, though some lenders go higher
- Verifiable, stable income
- A solid payment history on your existing mortgage
Your debt-to-income ratio is one of the first numbers an underwriter checks. If you are unsure where you stand, follow our guide on how to calculate your debt-to-income ratio before you apply.
How to Get a HELOC: Step by Step
Step 1: Estimate Your Home Equity
Look at recent sales of similar homes in your area or use an online value estimator, then subtract your mortgage balance. This gives you a rough idea of available equity before a lender orders an appraisal.
Step 2: Define Your Purpose and Budget
Decide how much you need and how you will repay it. Using a HELOC to add value to your home, such as a kitchen remodel or new roof, is generally a smarter use than funding vacations or everyday spending. Remember that your home is the collateral.
Step 3: Check Your Credit
Review your credit reports and fix any errors. Paying down revolving balances before applying can raise your score and help you qualify for a lower margin over prime.
Step 4: Compare Multiple Lenders
Get quotes from your current mortgage lender, local banks, credit unions, and online lenders. Compare:
- The starting APR and how it is calculated (prime plus a margin)
- Introductory or teaser rates and when they expire
- Rate caps limiting how high your rate can go
- Closing costs, appraisal fees, and annual fees
- Early closure fees if you close the line within a few years
- Minimum draw requirements and fixed-rate lock options
Step 5: Gather Your Documents
Prepare recent pay stubs, W-2s or tax returns, bank statements, your current mortgage statement, homeowners insurance details, and a government ID. Self-employed borrowers usually need two years of tax returns.
Step 6: Apply and Complete the Appraisal
After you apply, the lender verifies your information and orders a home appraisal or automated valuation to confirm your equity.
Step 7: Close and Use the Rescission Period
At closing, you sign the loan documents. For a HELOC on your primary residence, federal law generally gives you three business days to cancel without penalty. After that, you can access funds by check, online transfer, or a linked card.
Pros and Cons of a HELOC
Pros
- Lower interest rates than most unsecured debt
- Borrow only what you need, when you need it
- Interest-only payment options during the draw period
- Interest may be tax-deductible when funds are used to buy, build, or substantially improve the home securing the loan
Cons
- Your home is collateral, so missed payments can lead to foreclosure
- Variable rates can increase your payments
- Payment shock when the repayment period begins
- Falling home values could lead a lender to freeze or reduce your line
Smart Tips for Using a HELOC Responsibly
- Pay principal during the draw period, not just interest, to avoid a large jump in payments later.
- Borrow less than your full limit to keep a safety cushion.
- Watch rate changes and consider locking part of the balance at a fixed rate if rates are rising.
- Avoid funding depreciating purchases, such as luxury items, with home equity.
- Talk to a tax professional about whether your interest is deductible.

Frequently Asked Questions
How long does it take to get a HELOC?
Most HELOCs close in roughly two to six weeks, depending on the lender and appraisal timeline. Some online lenders move faster.
Does opening a HELOC affect my credit score?
The application causes a hard inquiry and a small temporary dip. Using a large share of the line may also affect your score, while on-time payments help it over time.
Can I get a HELOC on a rental property?
Some lenders offer HELOCs on investment properties, but they typically require more equity, stronger credit, and charge higher rates.
Final Thoughts
A home equity line of credit can be a flexible, low-cost way to fund major projects or replace high-interest debt. The key is borrowing with a plan: know your equity, compare several lenders, understand how your rate can change, and repay principal early. Treat your HELOC as a strategic tool, not extra spending money, and it can help you build wealth rather than put your home at risk.
