What a HELOC is and how to start one

A HELOC (home equity line of credit) is a loan where your home serves as collateral, and you borrow against the equity you have built up in it. Unlike a lump-sum home equity loan, a HELOC works like a credit card: the lender sets a credit limit based on your home's value and your equity, and you draw money as you need it, paying interest only on what you actually borrow.

To start a HELOC, you contact a bank, credit union, or mortgage lender, provide financial documents, and let them appraise your home. The lender checks your credit, income, and how much equity you have. If approved, you receive a line of credit you can tap into during the "draw period," which typically lasts five to ten years. After that, the "repayment period" begins, and you pay back what you borrowed plus interest.

The process usually takes two to four weeks from process to funding, though it can be faster with some lenders if you already bank there. You will need to be prepared with tax returns, pay stubs, bank statements, and a recent mortgage statement showing your current loan balance.

Key Takeaways

  • A HELOC lets you borrow money using your home as collateral, and you only pay interest on the amount you actually use.
  • Lenders will order a home appraisal, review your credit score and income, and verify how much equity you own in your home.
  • You will need recent tax returns, pay stubs, bank statements, and your mortgage statement to move forward with an process.
  • The draw period (when you can borrow) typically lasts five to ten years, followed by a repayment period when you must pay back the full balance.
  • Interest rates on HELOCs are usually variable, meaning your monthly payment can change if the market rate changes.

How much equity you need to have

Most lenders require you to have at least 15 to 20 percent equity in your home before they will open a HELOC. Equity is the difference between what your home is worth and what you still owe on your mortgage. If your home is worth $300,000 and you owe $240,000, you have $60,000 in equity, or 20 percent.

The amount of equity you have directly affects how much you can borrow. Lenders typically let you borrow up to 80 or 85 percent of your home's total value, minus what you still owe on your first mortgage. So if your home is worth $300,000 and you owe $240,000 on your mortgage, a lender might let you borrow up to $240,000 total (85 percent of $300,000), meaning you could access $0 in new funds because you are already at that limit with your mortgage. If you owed only $180,000, you could borrow up to $60,000 through a HELOC.

The lender will order a professional appraisal of your home to confirm its current value. This appraisal typically costs $300 to $500 and is usually paid by you upfront, though some lenders waive this fee if you meet certain income or credit requirements.

Credit score and income requirements

Most lenders want to see a credit score of at least 620, though many prefer 680 or higher. A higher score often means a lower interest rate. The lender will pull your credit report and look at your payment history, how much debt you carry, and how long you have had credit accounts open.

You will also need to show stable income. Lenders typically want to see two years of tax returns and recent pay stubs (usually the last two months). If you are self-employed, you may need to provide additional documentation like profit-and-loss statements or business tax returns. Some lenders have minimum income requirements, though these vary widely by institution.

Your debt-to-income ratio matters too. This is the percentage of your monthly income that goes toward debt payments. Most lenders want this ratio to be 43 percent or lower, meaning if you earn $5,000 per month, your total monthly debt payments (mortgage, car loans, credit cards, student loans, and the new HELOC payment) should not exceed about $2,150.

Documents you will need to gather

Before you contact a lender, collect these items so the process moves faster:

  • Two years of personal tax returns (1040 forms and all schedules)
  • Recent pay stubs, typically the last two months
  • Recent bank statements, usually the last two to three months
  • Your current mortgage statement showing the loan balance and interest rate
  • A recent property tax bill or homeowners insurance statement (to confirm you own the home)
  • Photo identification (driver's license or passport)
  • If self-employed: profit-and-loss statements or business tax returns
  • If you have changed jobs recently: an offer letter or employment verification letter

Having these ready before you explore speeds up the underwriting process. Some lenders let you upload documents through an online portal; others ask you to bring them in person or mail them. Ask your lender which method they prefer.

The appraisal and underwriting process

Once you submit your process, the lender orders a home appraisal. A licensed appraiser visits your home, measures it, photographs the interior and exterior, and compares it to similar homes that have sold recently in your area. The appraisal determines your home's current market value, which the lender uses to calculate how much you can borrow.

While the appraisal is underway, the lender's underwriting team reviews your financial documents. They verify your income by contacting your employer or reviewing tax returns, check your credit report in detail, and confirm that you have no recent late payments or collections. They also run a title search to make sure there are no liens or claims against your home other than your mortgage.

This stage typically takes one to two weeks. If the underwriter finds issues—such as a gap in employment, a recent late payment, or a discrepancy in your income—they will ask you to explain or provide additional documents. Once everything checks out, you move to the final approval stage.

Closing and funding your HELOC

After underwriting approves your HELOC, you will schedule a closing appointment. At closing, you sign the promissory note (the legal promise to repay the loan), the security agreement (which pledges your home as collateral), and other disclosure documents. You will also receive a Truth in Lending Act (TILA) disclosure that spells out the interest rate, any fees, and the terms of the draw and repayment periods.

Closing typically happens at a title company, your lender's office, or sometimes online with an electronic notary. The process usually takes 30 minutes to an hour. You may be asked to bring a cashier's check or arrange a wire transfer to cover closing costs, which typically range from $0 to $1,500 depending on your lender and state.

After closing, the lender records the HELOC as a second lien against your home (your mortgage is the first lien). Once recorded, you receive access to your credit line. Most lenders provide a checkbook, a debit card, or online access so you can draw funds whenever you need them during the draw period.

Interest rates and how HELOC payments work

HELOC interest rates are almost always variable, meaning they change based on the prime rate set by the Federal Reserve. Your rate is typically the prime rate plus a margin set by your lender (usually 1 to 3 percentage points). If the prime rate goes up, your rate goes up, and your monthly payment increases. If the prime rate drops, your payment decreases.

During the draw period, you typically pay interest-only on the amount you have borrowed. If you borrow $10,000 and your rate is 8 percent, you pay about $67 per month in interest. Once you stop borrowing and enter the repayment period, you begin paying principal and interest, and your payment rises significantly.

Some lenders offer a fixed-rate option on part or all of your HELOC, which locks in a rate for a set time. This protects you from rate increases but usually comes with a slightly higher rate than the variable option. Ask your lender whether this option is available and what it costs.

Frequently Asked Questions

Can I get a HELOC if I have bad credit?

It is harder but not impossible. Some lenders work with borrowers who have credit scores as low as 600, though you will likely face a higher interest rate and may need to put down a larger down payment or show more income stability. Credit unions sometimes have more flexible standards than banks. Start by contacting lenders directly to ask about their minimum credit score requirements.

What happens to my HELOC if my home value drops?

If your home's value falls significantly, your lender may freeze or reduce your credit line. During the 2008 housing crisis, many lenders froze HELOCs when home values dropped. Your existing balance is still owed, but you may not be able to borrow more. This is a real risk of using a HELOC.

Can I pay off my HELOC early without a penalty?

Most HELOCs have no prepayment penalty, so you can pay off the balance whenever you want. However, some lenders charge a small fee if you close the line of credit within a certain time frame (often three to five years). Check your loan documents or ask your lender about their prepayment policy before you sign.

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

A home equity loan gives you a lump sum upfront and you repay it on a fixed schedule with a fixed interest rate. A HELOC is a revolving line of credit where you borrow as needed and pay interest only on what you use. Home equity loans are better if you need a large amount all at once; HELOCs are better if you need money over time.

Do I have to use my HELOC right away?

No. Once your HELOC is open, you can leave it untouched for years. You only pay interest on money you actually borrow. However, some lenders charge an annual fee to keep the line open even if you do not use it. Ask about this before you sign.
