What a home equity line of credit actually is

A home equity line of credit, or HELOC, is a loan where your home serves as collateral and you can borrow against the equity you have built up in it. Unlike a traditional loan where you get all the money at once, a HELOC works more like a credit card — you have a maximum amount available to borrow, and you draw from it as you need the money. You pay interest only on what you actually borrow, not on the full credit line.

The lender looks at how much your home is worth, subtracts what you still owe on your mortgage, and that difference is your equity. If your home is worth $300,000 and you owe $200,000 on your mortgage, you have $100,000 in equity. Most lenders will let you borrow somewhere between 70 and 85 percent of that equity, though the exact amount depends on your credit score, income, and how stable your employment looks.

A HELOC typically has two phases: a draw period (usually 5 to 10 years) when you can borrow and repay as needed, and a repayment period (usually 10 to 20 years) when you can no longer borrow and must pay back what you owe. Interest rates on HELOCs are usually variable, meaning they move up and down with the market — this is different from a fixed-rate home equity loan, where the rate stays the same for the life of the loan.

Key Takeaways

  • A HELOC lets you borrow against your home's equity and draw money as you need it, paying interest only on what you use.
  • Lenders typically allow you to borrow 70 to 85 percent of your equity, but the exact amount depends on your credit score and income.
  • You will need recent pay stubs, tax returns, bank statements, and a current mortgage statement to start the process.
  • The lender will order an appraisal to confirm your home's value, which usually costs $300 to $500 and takes one to two weeks.
  • Interest rates on HELOCs are variable and can increase during the repayment phase, so your monthly payment may rise over time.

How much equity you need to have

Before you approach a lender, you need to know how much equity is actually in your home. Pull your most recent mortgage statement — it will show your current loan balance. Then find your home's current value. You can use online estimates from Zillow or Redfin, but lenders will order their own appraisal to verify the number, so those estimates are just a starting point.

Most lenders require you to have at least 15 to 20 percent equity remaining after the HELOC is issued. This means if you want to borrow $50,000 against $100,000 in equity, you would still have $50,000 left untouched. Some lenders are stricter and require 30 percent equity to remain. The reason is straightforward: if your home value drops or you fall behind on payments, the lender wants a cushion before they lose money.

If you have less equity than you thought, you have a few options. You can wait and let your mortgage balance drop naturally as you make payments, which builds equity over time. You can make a large lump-sum payment toward your mortgage principal to increase equity faster. Or you can look into a home equity loan instead, which some lenders offer more flexibly than a HELOC.

Documents you will need to gather

Lenders treat a HELOC process like a mortgage process in miniature. You will need to prove your income, show your assets, and demonstrate that you pay your bills on time. Start by gathering the following documents before you contact a lender:

  • Two recent pay stubs (usually from the last 30 days)
  • Two years of tax returns (personal and business if self-employed)
  • Two months of recent bank statements
  • Your current mortgage statement
  • A recent property tax bill or homeowners insurance statement
  • Proof of homeowners insurance

If you are self-employed or have income from multiple sources, be ready to provide additional documentation like profit-and-loss statements or 1099 forms. If you have changed jobs recently, bring an employment verification letter from your new employer. The lender will also pull your credit report, so you do not need to provide that yourself — they will see your credit score and payment history directly.

The appraisal and underwriting process

Once you submit your process, the lender will order an appraisal of your home. An appraiser will visit your property, measure it, look at its condition, and compare it to similar homes that have sold recently in your area. The appraisal usually costs $300 to $500 and takes one to two weeks to complete. You typically pay this fee upfront, though some lenders roll it into closing costs.

While the appraisal is happening, the lender's underwriting team reviews your documents. They verify your income by contacting your employer, check your credit report in detail, and calculate your debt-to-income ratio — the percentage of your monthly income that goes toward debt payments. Most lenders want this ratio to be below 43 percent, though some go up to 50 percent depending on your credit score and savings.

If the appraisal comes back lower than you expected, your available credit line shrinks. If it comes back higher, your available credit line grows. The underwriter may also ask for additional documents or explanations if something on your credit report looks unusual, like a late payment or a recent collection account. This back-and-forth usually takes one to three weeks.

Interest rates and how they work on a HELOC

Most HELOCs have a variable interest rate, which means the rate changes over time based on a market index — usually the prime rate set by the Federal Reserve. Your actual rate is the prime rate plus a margin that the lender adds on top. If the prime rate is 8 percent and the lender's margin is 1 percent, your rate is 9 percent. When the prime rate moves, your rate moves with it.

Some lenders offer a promotional rate period at the beginning, where your rate is fixed for a set time — often six months to a year. After that period ends, the rate becomes variable. A few lenders offer a fully fixed-rate option, but it usually comes with a higher starting rate and fewer lenders offer it.

During the draw period, you typically pay interest-only on what you have borrowed. Once you enter the repayment period, your payment jumps because you are now paying both principal and interest. If you borrowed $50,000 and your rate is 7 percent, your interest-only payment might be around $290 per month during the draw period. When repayment starts, that payment could jump to $500 or $600 per month depending on how many years you have to repay it. This is why it is important to understand what your payment will look like after the draw period ends.

Comparing a HELOC to a home equity loan

A home equity loan is different from a HELOC in important ways. With a home equity loan, you borrow a lump sum all at once and receive it as a single payment. You then repay that amount over a fixed period — usually 5 to 15 years — at a fixed interest rate. Your payment stays the same every month for the entire life of the loan.

A HELOC gives you flexibility: you borrow only what you need, when you need it, and your payment changes based on how much you have borrowed and what interest rates do. This makes a HELOC better if you are not sure exactly how much money you need or if you want to borrow gradually over time. A home equity loan is better if you need a specific amount upfront and want the certainty of a fixed payment that never changes.

Home equity loans also typically have lower interest rates than HELOCs because the rate is fixed and the lender knows exactly how much you are borrowing. HELOCs carry more risk for the lender because rates can move and you might borrow more later, so lenders charge a slightly higher rate to compensate. Both are secured by your home, meaning if you stop paying, the lender can foreclose.

Closing costs and fees to expect

A HELOC comes with closing costs similar to a mortgage. These typically include an appraisal fee ($300 to $500), a title search and insurance ($200 to $400), underwriting and processing fees ($300 to $800), and attorney fees if your state requires it ($150 to $400). Some lenders charge an annual fee to maintain the line of credit, usually $25 to $100 per year, though many waive this if you use the line.

Total closing costs usually range from $1,000 to $3,000, depending on your location and the lender. Some lenders offer no-closing-cost HELOCs, but they typically do this by charging a higher interest rate instead — you are paying the cost over time rather than upfront. Compare the total cost of both options before deciding.

You will also receive a Truth in Lending disclosure that shows your APR, the terms of the draw and repayment periods, and what your payment might look like. Read this carefully and ask questions if anything is unclear. This is a legal document designed to help you understand the full cost of borrowing.

Where to find lenders and what to compare

Banks, credit unions, and online lenders all offer HELOCs. Start by checking with your current mortgage lender — they already have your information and may offer a discount or faster processing. Then contact at least two or three other lenders to compare rates and terms. Call your local credit union if you are a member; credit unions often offer lower rates than banks.

When you compare, look at the interest rate, the margin above the prime rate, any promotional rate period, the draw period length, the repayment period length, closing costs, and any annual fees. Ask each lender what happens to your rate when the promotional period ends and what the maximum rate could be if interest rates rise significantly. Some HELOCs have a rate cap that limits how high the rate can go; others do not.

Get a written quote from each lender that shows all these terms. Do not rely on phone conversations — written quotes are binding and let you compare apples to apples. Most lenders will hold a rate quote for 30 to 45 days, giving you time to decide.

Frequently Asked Questions

Can I get a HELOC if I have a low credit score?

Most lenders require a credit score of at least 620, though many prefer 680 or higher. If your score is below 620, some credit unions and online lenders may still work with you, but you will pay a higher interest rate. The best move is to spend a few months paying down debt and making all payments on time to raise your score before you explore.

What happens to my HELOC if my home value drops?

If your home value falls significantly, the lender can reduce your available credit line or freeze it entirely. They cannot force you to repay what you have already borrowed, but they can prevent you from borrowing more. This happened to many homeowners during the 2008 housing crisis. To protect yourself, avoid borrowing the maximum amount available — keep some cushion in case your home value dips.

Can I use a HELOC for anything I want?

Yes, legally you can use the money for anything — home renovations, debt consolidation, education, or a vacation. However, remember that your home is collateral. If you cannot repay the money, you risk losing your home. Use a HELOC only for expenses that are worth the risk, like home improvements that increase your home's value or consolidating high-interest debt.

What if I cannot pay back the HELOC during the repayment period?

Contact your lender when ready and ask about options. Some lenders will extend the repayment period, lower your payment temporarily, or convert the HELOC to a fixed-rate loan. If you do nothing, the lender will eventually foreclose on your home. Do not wait until you are behind on payments — call as soon as you know you are in trouble.

How long does the whole process take from process to receiving money?

The typical timeline is four to six weeks. process and document review take one to two weeks, the appraisal takes one to two weeks, underwriting takes one to three weeks, and closing takes a few days. Some lenders are faster, especially if you are an existing customer. Ask the lender for a timeline estimate when you explore.
