If you’ve built up significant equity in your home and need cash for a major expense, you don’t have to sell to access it. What is a home equity loan? A home equity loan is a type of second mortgage that lets you borrow a lump sum against the value you’ve built up in your home, repaid over time at a fixed interest rate. This guide explains exactly how a home equity loan works, what it costs, how it compares to a HELOC and a cash-out refinance, and when it actually makes sense to use one.

What is a home equity loan, exactly?
What is a home equity loan? According to the Consumer Financial Protection Bureau, a home equity loan, sometimes called a HEL, allows you to borrow money using the equity in your home as collateral, and you receive the money as a single lump sum with a fixed interest rate that won’t change over the loan term.
Because this type of loan is secured by your property, it’s often called a second mortgage — it sits behind your primary mortgage but still gives the lender a legal claim on your home if you fail to repay. This is exactly what makes it different from an unsecured personal loan or credit card: the lower rate you get comes directly from the risk you’re accepting by putting your home on the line.
How home equity is calculated
Before understanding what this loan type can offer you, it helps to understand what equity actually is. According to Equifax, equity is the difference between your home’s current market value and the remaining balance on your mortgage.
| Component | Amount |
|---|---|
| Current home market value | $450,000 |
| Remaining mortgage balance | $250,000 |
| Total home equity | $200,000 |
Most lenders won’t let you borrow against all of that equity through this loan type. According to Banks.com, a home equity loan is typically capped at 85% of your home’s equity, repayable in equal monthly installments over a 20- to 30-year period.
How a home equity loan actually works
Once approved, this loan type is disbursed as a single lump sum, deposited directly into your bank account. According to U.S. Bank, both the interest rate and monthly payments on this loan type are fixed, ensuring a predictable repayment schedule for the life of the loan.
You then repay that lump sum in fixed monthly installments, just like your primary mortgage, until the loan is paid off. Because it’s a second mortgage, you’ll have two separate monthly payments running simultaneously: your original mortgage payment and your new payment on this loan, both secured by the same property.
A real example with actual math
Let’s walk through a concrete example. Say your home is worth $450,000, you owe $250,000 on your mortgage, giving you $200,000 in equity. You take out an $80,000 loan of this type at a fixed 8% interest rate over a 15-year term to renovate your kitchen and pay off high-interest credit card debt.
| Detail | Amount |
|---|---|
| Loan amount | $80,000 |
| Fixed interest rate | 8% |
| Loan term | 15 years |
| Fixed monthly payment | $765 |
| Total interest paid over 15 years | $57,700 |
This $765 monthly payment is entirely separate from your existing mortgage payment, and it never changes for the full 15 years, regardless of what happens to interest rates in the broader market. That predictability is one of the defining features of this loan type compared to a variable-rate alternative like a HELOC.
Home equity loan vs. HELOC
The most common comparison people make once they understand this loan type involves its close cousin, the Home Equity Line of Credit, or HELOC.
| Home equity loan | HELOC | |
|---|---|---|
| How funds are disbursed | One-time lump sum | Revolving credit line, draw as needed |
| Interest rate | Fixed | Usually variable |
| Payment predictability | Fixed monthly payment | Payment can change as rate or balance changes |
| Best for | One-time expenses with a known cost | Ongoing or uncertain expenses |
| Repayment | Starts immediately | Interest-only draw period, then repayment period |
According to Experian, a home equity loan is a lump sum of money secured by your home and repaid in fixed monthly installments over a term that typically ranges from five to 30 years, while a HELOC functions more like a credit card secured by your home. If you know exactly how much you need and want predictable payments, this loan type is usually the simpler choice; if your expense is ongoing or uncertain, a HELOC’s flexibility may fit better.
Home equity loan vs. cash-out refinance
A cash-out refinance replaces your entire existing mortgage with a new, larger one, giving you the difference in cash. This type of loan, by contrast, leaves your original mortgage completely untouched and simply adds a second loan on top of it.
This distinction matters enormously if your existing mortgage has a low interest rate. Refinancing would mean giving up that low rate on your entire loan balance, while this loan type lets you keep your original mortgage rate intact and only pay the typically higher rate on the new amount you’re borrowing.
Home equity loan vs. a regular mortgage
According to Bankrate, a mortgage lets you purchase a property, while a home equity loan — which is a type of second mortgage — allows you to tap the value of your property to get cash, and you can obtain one either after paying off your original mortgage or while you’re still repaying it.
In other words, a regular mortgage is how you buy a home in the first place, while this loan type is how you access the value you’ve already built up in a home you own. You cannot use this loan type to purchase your primary residence — that’s specifically what a purchase mortgage is for.
What people actually use a home equity loan for
This type of loan can technically be used for almost anything, but certain uses are far more common than others.
- Home renovations and repairs — the single most common reason people take out this loan type
- Debt consolidation — paying off high-interest credit card debt with a lower fixed rate
- Education expenses — covering tuition or other major education costs
- Major medical expenses — funding significant, unplanned healthcare costs
- Large purchases — vehicles or other big-ticket items, though this is riskier given the collateral involved
According to U.S. Bank, homeowners commonly use this type of loan to consolidate debt or pay for large expenses such as home improvements, education, or purchasing a vehicle, precisely because the fixed rate is usually significantly lower than credit card or personal loan rates.
Pros and cons of a home equity loan
| Pros | Cons |
|---|---|
| Fixed rate and predictable payments | Your home is collateral — default risks foreclosure |
| Lower interest rate than credit cards or personal loans | Adds a second monthly payment on top of your mortgage |
| Lump sum ideal for known, one-time costs | Closing costs apply, similar to a first mortgage |
| Interest may be tax-deductible if used for home improvements | Reduces your home equity cushion |
| Doesn’t touch your original mortgage rate | Approval depends on credit, income, and available equity |
How to qualify for a home equity loan
Lenders evaluate an application for this loan type similarly to a first mortgage, focusing on a few key factors.
- Sufficient equity — most lenders require you to retain at least 15-20% equity after the new loan
- Credit score — typically 620 or higher, though better rates require 700+
- Debt-to-income ratio — lenders generally want this under 43-50%
- Stable income and employment history — proof you can handle two simultaneous mortgage payments
- Home appraisal — confirms current market value to calculate available equity accurately
How to get a home equity loan step by step
- Calculate your available equity — current home value minus your remaining mortgage balance
- Check your credit score — know where you stand before applying
- Shop multiple lenders — rates and fees vary meaningfully between banks and credit unions
- Get a home appraisal — most lenders require this to confirm current value
- Compare the fixed rate against a HELOC or cash-out refinance for your specific situation
- Review closing costs — typically 2-5% of the loan amount, similar to a first mortgage
- Close and receive your lump sum — funds are typically disbursed within a few days of closing
The real risks of a home equity loan
The single biggest risk of this loan type is that it’s secured by your home. If you fall behind on payments, the lender can foreclose, just as they could with your primary mortgage. This is fundamentally different from unsecured debt like credit cards, where default damages your credit but doesn’t put your house at risk.
This loan type also reduces the equity cushion you’ve built, which matters if home values decline. Borrowing too aggressively against your equity can leave you owing more than your home is worth if the market shifts, a situation that limits your options if you need to sell or refinance later.
Where the home equity loan came from
Borrowing against home value isn’t a new idea, but the modern, standardized version of this loan type became widespread in the U.S. starting in the 1980s, once tax law changes made interest on this kind of borrowing deductible under certain conditions, unlike most consumer debt. That tax treatment, combined with rising home values through the following decades, made tapping equity an increasingly mainstream financial tool rather than a niche product.
Regulation has tightened considerably since the 2008 housing crisis, when loose lending standards on second mortgages contributed to widespread defaults. Today, lenders apply much stricter equity, income, and credit requirements before approving this type of loan, which has made it a considerably safer product than it was two decades ago.
Why shopping multiple lenders matters so much
Rates and fees on this loan type vary more between lenders than many borrowers expect, even for applicants with identical credit profiles and equity positions. A difference of even half a percentage point on an $80,000 loan can add up to thousands of dollars in extra interest over a 15-year term, simply based on which lender you chose.
Credit unions often offer more competitive rates than large national banks for this kind of secured borrowing, since they typically operate with lower overhead and prioritize member value over profit margins. Getting at least three quotes, and specifically asking each lender to itemize closing costs upfront, is the single most effective way to avoid overpaying.
Alternatives worth considering first
Before committing to this type of secured borrowing, it’s worth weighing a few alternatives that don’t put your home at risk. A 0% introductory APR credit card can cover smaller expenses temporarily without any collateral risk, though it requires paying off the balance before the promotional period ends. Personal loans, while carrying higher rates than a secured option, don’t risk foreclosure if repayment becomes difficult.
For larger renovation projects specifically, some homeowners also explore building a dedicated savings fund over a longer timeline instead of borrowing at all, trading speed for the certainty of not adding any new debt or collateral risk to the picture.
Understanding the tax deduction rules
The potential tax deductibility of interest on this type of borrowing is one of its most misunderstood features. Under current IRS rules, interest is only deductible when the borrowed funds are used to buy, build, or substantially improve the specific home securing the debt — using the money to pay off credit cards, cover a vacation, or fund a car purchase disqualifies that interest from being deducted, even though the loan itself is still perfectly valid for those purposes.
Because the rules changed significantly with the 2017 Tax Cuts and Jobs Act, many homeowners still assume all interest on this kind of secured borrowing is automatically deductible the way it once was. Keeping clear records of exactly how funds were spent, ideally with receipts tied to specific home improvement projects, makes claiming this deduction far easier if you’re ever asked to substantiate it. A qualified tax professional can confirm whether your specific situation qualifies before you file.
Frequently asked questions about home equity loans
What is a home equity loan used for most often?
Home renovations and debt consolidation are the two most common uses. Its fixed, typically lower interest rate makes it especially attractive for paying off high-interest credit card debt or funding a major home improvement project.
Is a home equity loan a good idea?
It can be, especially for a known, one-time expense where you want predictable fixed payments. It’s less ideal for uncertain or ongoing costs, where a HELOC’s flexibility may serve you better, and it always carries the risk of foreclosure if you can’t keep up with payments.
How much can I borrow with a home equity loan?
Most lenders cap this loan type at 80-85% of your total home equity, though the exact amount depends on your credit score, income, and the lender’s specific policies.
Does a home equity loan affect my original mortgage?
No. This loan type is a separate second mortgage that sits behind your original loan. Your existing mortgage rate, term, and payment remain completely unchanged when you take out one of these loans.
Is the interest on a home equity loan tax-deductible?
It can be, if the funds are used to buy, build, or substantially improve the home securing the loan, according to current IRS rules. Interest used for other purposes, like debt consolidation, generally isn’t deductible. Consult a tax professional for your specific situation.
The bottom line on home equity loans
Now that you understand what a home equity loan is, the decision comes down to whether you have a known, one-time expense and want the predictability of a fixed rate over the flexibility of a HELOC. Compare offers from multiple lenders, understand the closing costs involved, and never borrow more than you’re confident you can repay given the collateral at stake.
