How to apply for a home equity line of credit (HELOC)

If you’ve built equity and want flexible access to funds, a home equity line of credit (HELOC) could help you cover renovations, tuition, debt consolidation, and more. While Rocket Mortgage doesn’t currently offer HELOCs, here’s how to apply for a HELOC in 6 simple steps, plus the requirements, costs, and pros and cons to consider before you decide.

What is a HELOC?

A home equity line of credit is a second mortgage that uses your home as collateral for a line of credit.

You can draw on this line of credit up to your limit as needed during your HELOC's draw period, which usually lasts about 10 years. You usually can access your HELOC with a card, checks, or online transfers.

After the draw period, you can no longer draw on the line of credit and make payments until you pay off the balance.

You’ll only pay interest on the amount you spend, not the full amount you’re approved for.

Most HELOCs have a variable mortgage interest rate, which means your rate and monthly payment can fluctuate depending on market conditions. If interest rates increase, your borrowing costs could increase, too.

HELOC requirements

While HELOC requirements vary from lender to lender, there are common requirements.

• Reliable income: Most lenders will ask for proof of income to make sure you can afford the loan.
• Good credit: Lenders will run your credit and may require you to meet a minimum credit score.
• Sufficient equity: You should have at least 15% – 20% home equity. Your lender usually won't allow you to borrow all your equity.
• Responsible payment history: Lenders will review your payment history to ensure you've paid your bills and debts on time.
• Manageable debt load: The lower your debt-to-income (DTI) ratio, the better. DTI shows how much of your income is required to pay your monthly debts. Lenders usually want to see a DTI below 43%.
• Home appraisal: The lender usually requires a professional home appraisal to confirm its fair market value and how much equity you have.

How to get a HELOC loan in 6 steps

You'll want to figure out how much equity you have, as this will determine how much you can borrow with a HELOC.

To do this, calculate your loan-to-value (LTV) ratio. Divide your current mortgage balance (found on your most recent mortgage statement) by your home’s current appraised value. Then, multiply by 100 to get the percentage.

So, if you owe $300,000 on your mortgage and your home is worth $500,000, the LTV calculation would look like this:

$300,0000 / $500,000 x 100 = 60%

If your LTV is 60%, that means your home equity is 40%. You can also use an online LTV calculator if you prefer not to do the math manually.

Your LTV is important because it affects how much you can borrow against your home’s equity. Many lenders require an LTV no higher than 80%. If your LTV is 75%, it typically means you can access 5% of your equity for a HELOC.

Some lenders allow higher LTV limits for borrowers with strong creditworthiness. This is one reason to check your credit and address any negative factors or errors before applying.

You also can use the home equity calculator from Rocket Mortgage.

Now, let’s look at how to take out a HELOC.

1. Find a lender

Just like when you’re looking for the best deal on a car or plane ticket, shopping for a HELOC is vital. Different lenders offer different terms and rates. A key thing that varies is that some lenders offer interest-only payments during the draw period, which means you pay nothing toward the principal.

An important question is whether the HELOC has a balloon payment. This means that the lender may require a large lump-sum payment at the end of your loan term. This can be difficult to afford if you’re not prepared.

Also ask your mortgage lender about fees, the monthly payment amount, interest rates, loan types (such as adjustable versus fixed-rate loans), and potential credit qualifications. 

2. Gather documents and apply

It’s best to gather your financial documents before submitting your HELOC application to avoid delays. You usually will need to provide proof of income documents, such as bank statements, W-2 forms, recent pay stubs, and income tax returns.

3. Get an appraisal

An appraisal provides the most accurate estimate of your home's fair market value. Professional appraisals use recent sales of comparable nearby properties – usually called comps – and consider your home’s specific features. Don’t forget to make your home look as good as you can on appraisal day. Poor upkeep, clutter, disrepair, unkempt lawns, unfinished renovations, and other negatives can affect your home appraisal.

4. Close on your new line of credit

Following the appraisal, which the lender will see, the lender will tell you how much you qualify for, the interest rate they’re offering, and other important terms.

If you accept the terms, you’ll sign the paperwork – sometimes online, sometimes in-person – and receive your HELOC. You should expect to pay closing costs on your line of credit. Some lenders allow these fees to be rolled into the loan amount.

5. Start the draw period

The draw period is when you can borrow from your HELOC. Most lenders offer a 10-year draw period. You can withdraw up to your approved limit.

Some lenders have a minimum draw amount or require you to maintain a minimum balance. Others may require an initial withdrawal when the credit line is opened.

Monthly payments during the draw period usually cover interest and may include a small principal payment. However, in many cases, those payments won't be sufficient to fully repay the loan by the end of the term. Some plans only require interest payments during the draw period, which means your principal balance won't go down at all until repayment begins.

6. Pay back the HELOC

Once the draw period ends, you’ll enter the repayment period, which could be up to 20 years. You can no longer borrow funds from your HELOC. This time is specifically for repayment.

If you have a fixed-rate HELOC, your monthly payment will remain the same. If you have an adjustable-rate HELOC, your payments may fluctuate as your interest rate adjusts. Your HELOC may have rate caps that limit how much your rate can adjust. These will be explained in your loan documents and should be checked and understood before signing.

HELOC vs. home equity loan: What’s the difference?

Home equity loans and HELOCs are both second mortgages that let you borrow your home’s equity, but there are key differences.

HELOCs are lines of credit, and you can borrow as little or as much as you want, as often as you want, up to the credit limit you qualify for.

A home equity loan is a more traditional loan. You're paid a lump sum when you close on the loan and then make payments. Typically, a home equity loan has a fixed interest rate, while a HELOC has an adjustable-rate.¹

Both use your home’s equity for collateral. This is important because if you default on your HELOC or home equity loan, the lender can foreclose on your home to recover its money.

Should you apply for a HELOC?

Here are a few questions to consider before getting a home equity line of credit:

• Do I have a clear purpose for the funds? Make sure you know how you plan to use the money. Whether it’s for home improvements, consolidating debt, or something else, having a well-defined purpose can help you borrow responsibly.
• Do I meet the basic requirements? Check that you’re in a good position to qualify. If not, it may be worth spending some time strengthening your finances.
• How much do I really need to borrow? A HELOC's flexibility can be helpful, but it also can make it easy to borrow more than you intended. Go in with a firm estimate so you only borrow what you need.
• Can I comfortably repay what I borrow? It’s essential to be sure you can afford a HELOC. Missing payments could hurt your credit and put your home at risk.
• Have I explored other options? A home equity loan or a cash-out refinance is also worth considering, depending on your goals and financial situation.

The bottom line: How do I apply for a HELOC?

A HELOC lets you borrow your equity as needed up to your limit, making it a flexible way to borrow money. Before applying for a HELOC, you'll want to shop around for the best terms, gather your financial documents, get an appraisal, and close on your new loan. You'll then have a draw period where you can access your HELOC as needed, followed by a repayment period. Typically, HELOCs have an adjustable interest rate; however, fixed-rate HELOCs are available.
