Getting a HELOC means borrowing against your home's equity, and the process starts with your lender

To get a HELOC, you need to contact a bank, credit union, or mortgage lender, provide proof of your home's value and your equity in it, and let them verify your income and credit. Most lenders require you to own at least 15 to 20 percent of your home outright — meaning you owe that much less than it is worth. The lender will order an appraisal, pull your credit report, and review your debt-to-income ratio. If you pass, you receive a credit line you can draw from as needed, usually during a 10-year "draw period" when you can borrow and repay repeatedly.

The timeline from first contact to having money available typically runs 2 to 6 weeks, depending on how quickly you provide documents and how busy the lender is. You will pay closing costs similar to a mortgage refinance — usually 2 to 5 percent of the credit line amount — though some lenders waive these fees to compete for your business.

Key Takeaways

  • You must have equity in your home — typically at least 15 to 20 percent ownership — before a lender will approve a HELOC.
  • Lenders will order an appraisal, check your credit score, and verify your income and existing debts before deciding whether to approve you.
  • Closing costs for a HELOC usually range from 2 to 5 percent of the credit line amount, though some lenders waive them.
  • Once approved, you enter a draw period (usually 10 years) when you can borrow and repay as often as you want, then a repayment period when you can only pay down the balance.

What documents you need to gather before applying

Start by collecting proof of your home's current value and what you still owe on your mortgage. You will need your most recent mortgage statement, a property tax assessment, or a recent appraisal if you have one. If you have sold a similar home nearby recently, that sale price helps too.

Next, gather income documentation: recent pay stubs (usually the last two months), W-2s or tax returns from the past two years, and a letter from your employer confirming your job and salary. If you are self-employed, bring two years of tax returns and possibly a profit-and-loss statement. You will also need to provide bank statements (usually the last two months) to show you have cash reserves, and a list of your debts — credit cards, car loans, student loans, and any other monthly obligations.

Finally, bring a government-issued ID and be ready to authorize a credit check. Some lenders ask for a utility bill or recent property tax bill to confirm your address.

How lenders calculate how much you can borrow

Lenders use a formula based on your home's appraised value minus what you still owe on your mortgage. If your home is worth $300,000 and you owe $200,000, you have $100,000 in equity. Most lenders will let you borrow 80 to 90 percent of your total equity, meaning you could access $80,000 to $90,000 in this example.

However, the lender also looks at your debt-to-income ratio — your total monthly debt payments divided by your gross monthly income. If you already carry high credit card balances or car loans, the lender may reduce the credit line or deny you altogether. A ratio below 43 percent is generally favorable; above 50 percent makes approval difficult.

Your credit score matters too. Most lenders prefer a score of 700 or higher, though some will work with scores as low as 620. A lower score may mean a smaller credit line or a higher interest rate.

The difference between fixed and variable rate HELOCs

A variable-rate HELOC has an interest rate that moves with the market, usually tied to the prime rate. During the draw period, you typically pay interest only on what you have actually borrowed. When rates rise, your payment rises too. This is cheaper upfront but riskier if rates climb significantly.

A fixed-rate HELOC locks in one interest rate for the life of the line. Some lenders offer a hybrid: a variable rate during the draw period, then a fixed rate during repayment. Fixed rates are usually higher than the starting variable rate, but they protect you from payment shock if rates spike.

Ask your lender what the current prime rate is and what margin they add on top of it. The margin is typically 1 to 3 percentage points and does not change, even if the prime rate does. Also ask whether there is a floor rate — a minimum rate you will pay even if the prime rate falls.

What happens after you are approved

Once the lender approves you, you will sign closing documents similar to a mortgage closing. You will receive a disclosure showing your credit limit, the interest rate or rates, any annual fees, and the terms of the draw and repayment periods. Read this carefully — it is your contract.

After closing, the lender will issue you a checkbook, debit card, or online access to draw from your line. You do not have to use it all at once. During the draw period, you can borrow $5,000 one month and $15,000 six months later. Interest accrues only on what you have borrowed, not on the full credit line.

When the draw period ends (typically after 10 years), you enter the repayment period. At this point, you can no longer borrow new money — you can only pay down what you owe. The repayment period usually lasts 10 to 20 years. Your payment will likely jump because you are now paying both principal and interest, not just interest.

Common reasons lenders deny HELOC applications

The most common reason is insufficient equity. If you owe more than 80 to 85 percent of your home's value, most lenders will not approve you. A recent drop in home values can push you into this position even if you were approved years ago.

High debt-to-income ratio is the second major reason. If your existing monthly payments — mortgage, credit cards, car loans, student loans — already consume 43 percent or more of your gross income, the lender sees you as overextended and will decline.

A low credit score, missed payments in the past two years, or a recent bankruptcy or foreclosure will also result in denial. Some lenders have minimum score requirements of 680 or 700. If your score is below 650, you will have difficulty finding any lender willing to approve you.

Job instability or a recent job change can raise red flags. Lenders want to see at least two years of stable income history. If you changed jobs within the past six months, some lenders will ask for a letter from your new employer or will wait before approving you.

Alternatives if you cannot get a HELOC

A home equity loan (also called a second mortgage) works similarly but gives you a lump sum upfront instead of a credit line. You receive all the money at closing and begin repaying immediately on a fixed schedule. This is easier to get if your credit is weaker, because the lender knows exactly how much you are borrowing and when you will repay it.

A cash-out refinance replaces your existing mortgage with a new, larger one and gives you the difference in cash. This works only if interest rates are favorable or if you have significant equity. You will pay closing costs again and restart your mortgage term, so this is best if you plan to stay in the home long-term.

If your credit score is the barrier, consider spending 6 to 12 months paying down credit card balances and making all payments on time before reapplying. Even a 50-point improvement in your score can change a lender's decision.

Frequently Asked Questions

Do I have to use my HELOC right away?

No. Once approved, you can leave the credit line unused for years. You typically pay no interest or fees on money you have not borrowed. However, some lenders charge an annual fee whether you use the line or not, so read your disclosure carefully.

What happens to my HELOC if my home value drops?

The lender can freeze or reduce your credit line if your home's value falls significantly. This happened to many homeowners during the 2008 housing crisis. The lender may also require you to pay down the balance if you have borrowed money. Check your disclosure to see what circumstances allow the lender to take these actions.

Can I pay off my HELOC early?

Yes, and most lenders do not charge a prepayment penalty. You can pay off the entire balance whenever you want. However, once you pay down the balance, that money becomes available to borrow again — the line does not close unless you request it.

What is the difference between a HELOC and a home equity loan?

A HELOC is a revolving credit line like a credit card — you borrow, repay, and borrow again. A home equity loan gives you one lump sum and a fixed repayment schedule. HELOCs are more flexible but riskier if rates rise; home equity loans are more predictable but less flexible.

Will getting a HELOC hurt my credit score?

A hard inquiry and a new account will temporarily lower your score by a few points, usually 5 to 10. However, if you do not borrow on the line, the account will help your credit over time because it increases your available credit and shows responsible credit management.
