What Is a Home Equity Loan and How Does It Work?
A home equity loan — sometimes called a second mortgage — lets you borrow a lump sum of money using the equity you’ve built in your home as collateral. Equity is simply the difference between what your home is worth and what you still owe on your mortgage.
For example, if your home is worth $400,000 and you owe $220,000 on your mortgage, you have $180,000 in equity. Most lenders will let you borrow up to 80% to 85% of your home’s appraised value, minus what you owe. In this scenario, that could mean access to roughly $100,000 to $120,000.
Unlike a HELOC (Home Equity Line of Credit), which works like a revolving credit card, a home equity loan gives you one fixed lump sum, repaid over a set term — typically 5 to 30 years — at a fixed interest rate. Your monthly payment stays the same from day one to the last payment. That predictability is one of its biggest advantages.
This type of loan is available through banks, credit unions, and online lenders. Because your home secures the debt, lenders take on less risk — which usually translates into lower interest rates compared to personal loans or credit cards.
Key Benefits of a Home Equity Loan
According to the Federal Reserve’s 2025 consumer finance data, the average homeowner in the U.S. holds over $300,000 in home equity — a historically high figure driven by years of home price appreciation. For many Americans aged 35 to 65, that equity represents their single largest financial asset.
Here’s why a home equity loan can be a powerful financial tool when used responsibly:
- Lower interest rates: Home equity loan rates have generally ranged between 7% and 9% in recent years — far below the average credit card APR of over 21%, according to Bankrate. That spread can save you thousands of dollars in interest.
- Fixed payments: You’ll always know exactly what you owe each month, making budgeting straightforward.
- Potentially tax-deductible interest: Under current IRS rules (IRS Publication 936), interest on a home equity loan may be deductible if the funds are used to buy, build, or substantially improve the home securing the loan. Consult a CPA to confirm your eligibility.
- Large borrowing amounts: Depending on your equity and creditworthiness, you could access six figures — far more than most unsecured loan options.
- Lump-sum structure: Ideal for one-time, large expenses where you know the exact cost upfront.
Common legitimate uses include home renovations, paying off high-interest credit card debt, funding education, or covering major medical expenses. Using the proceeds wisely — especially for home improvements — can even increase the value of your property.
How to Get a Home Equity Loan: Step-by-Step
Getting approved for a home equity loan follows a structured process. Here’s what to expect, step by step:
- Check your equity position. Request a recent mortgage statement and get an estimate of your home’s current market value. Online tools like Zillow or Redfin can give you a ballpark, but a formal appraisal will be required by the lender.
- Review your credit score. Most lenders require a minimum credit score of 620, but to qualify for the best rates, you’ll want a score of 700 or higher. Pull your free credit report at AnnualCreditReport.com before applying.
- Calculate your combined loan-to-value (CLTV) ratio. This is: (current mortgage balance + desired loan amount) ÷ home’s appraised value. Most lenders cap CLTV at 80%-85%. If yours is higher, you may not qualify.
- Shop multiple lenders. Don’t accept the first offer. Compare at least three to five lenders — your current bank, a credit union, and an online lender like LendingTree or Better.com. Rates, fees, and terms vary significantly.
- Gather your documents. Lenders will ask for recent pay stubs, W-2s or tax returns for the past two years, your current mortgage statement, homeowner’s insurance proof, and a government-issued ID.
- Submit your application. Once you choose a lender, submit your application. Expect a hard credit inquiry at this stage, which can temporarily lower your credit score by a few points.
- Get your home appraised. The lender will order an official appraisal — expect to pay $300 to $600 for this. The appraised value determines how much you can borrow.
- Review your loan estimate and close. You’ll receive a Loan Estimate document within three business days of applying. Review all fees carefully before signing. Closing typically takes 2 to 4 weeks and includes closing costs of 2% to 5% of the loan amount.
Costs, Fees, and Risks You Must Understand
A home equity loan can be a smart financial move — but it comes with real costs and serious risks that you should never underestimate.
Upfront and Ongoing Costs
- Closing costs: Typically 2% to 5% of the loan amount. On a $50,000 loan, that’s $1,000 to $2,500 out of pocket at closing.
- Origination fees: Some lenders charge 1% to 2% of the loan to process your application.
- Appraisal fee: Usually $300 to $600, paid upfront.
- Prepayment penalties: Some lenders charge a fee if you pay off the loan early. Always check the fine print before signing.
The Biggest Risk: You Can Lose Your Home
This is not a metaphor. Because your house is the collateral, defaulting on a home equity loan can result in foreclosure. If your income drops, you lose your job, or a financial emergency hits, missing payments on a home equity loan is far more serious than missing a credit card payment.
Variable Market Risk
Home values don’t always go up. If your home’s value drops significantly after you take out the loan, you could end up underwater — owing more than the home is worth. That can make it very difficult to sell or refinance.
Interest Rate Context
While home equity loan rates are fixed, the rate you lock in depends on market conditions at the time you borrow. In a high-rate environment, even a “cheap” secured loan can still carry a meaningful cost over 10 to 20 years.
Common Mistakes to Avoid With Home Equity Loans
Many homeowners make costly errors when tapping into their equity. Here are the most common — and how to sidestep them:
Mistake #1: Borrowing for Lifestyle Expenses
Using a home equity loan to fund vacations, luxury purchases, or everyday expenses is a high-risk move. You’re converting unsecured consumer debt risk into secured debt backed by your home. If the spending doesn’t generate lasting value, you’ve put your property at risk for nothing.
Mistake #2: Not Shopping Around for Rates
NerdWallet research consistently shows that borrowers who compare at least three lenders save an average of $1,500 or more over the life of a loan. Many people go straight to their existing bank and accept the first offer — leaving money on the table.
Mistake #3: Ignoring the Total Cost of Borrowing
A $80,000 home equity loan at 8.5% over 15 years means you’ll repay over $141,000 total. Always use a loan amortization calculator before you sign to understand the true cost — not just the monthly payment.
Mistake #4: Forgetting About Closing Costs
Some borrowers focus only on the interest rate and forget to account for 2% to 5% in closing costs. Those costs are often rolled into the loan balance, meaning you’re paying interest on them for years.
Mistake #5: Not Having a Clear Repayment Plan
Before borrowing, you should know exactly how you’ll repay the loan. Factor in both your current income and a “worst case” scenario — job loss, reduced hours, or unexpected expenses. If your budget doesn’t comfortably support the new payment, reconsider.
Alternatives to a Home Equity Loan
A home equity loan isn’t the right tool for every situation. Here are three alternatives worth evaluating:
1. HELOC (Home Equity Line of Credit)
A HELOC gives you access to a revolving line of credit based on your equity — similar to a credit card. You draw what you need, when you need it, and only pay interest on what you borrow. Rates are typically variable, which can work in your favor if rates drop — but also means your payment can rise. A HELOC is better suited for ongoing expenses like a multi-phase home renovation rather than a one-time lump-sum need. Learn more about managing your tax strategy if you’re weighing multiple borrowing options simultaneously.
2. Cash-Out Refinance
With a cash-out refinance, you replace your existing mortgage with a larger one and pocket the difference in cash. This can make sense if current mortgage rates are lower than your existing rate — but in a high-rate environment, refinancing your primary mortgage to access equity could significantly increase your total interest costs over time.
3. Personal Loan
If your borrowing need is smaller — say, under $25,000 — an unsecured personal loan might be worth considering. You won’t put your home at risk, and top-tier borrowers can find rates in the 9% to 12% range. The tradeoff is a higher interest rate and shorter repayment terms.
Frequently Asked Questions
How much can I borrow with a home equity loan?
Most lenders allow you to borrow up to 80% to 85% of your home’s appraised value, minus your current mortgage balance. For example, if your home is worth $350,000 and you owe $200,000, the maximum you could borrow is approximately $97,500 (85% of $350,000 minus $200,000).
Is the interest on a home equity loan tax deductible?
It can be, but only if the funds are used to buy, build, or substantially improve the home that secures the loan — per IRS Publication 936. If you use the money for other purposes, such as paying off credit cards or a vacation, the interest is generally not deductible. Always consult a CPA for your specific situation.
How long does it take to get a home equity loan?
The process typically takes 2 to 4 weeks from application to funding, depending on the lender’s workload, how quickly your appraisal is completed, and how fast you submit documentation.
What credit score do I need?
The minimum is generally 620, but borrowers with scores below 680 may face significantly higher rates or stricter equity requirements. A score of 700 or above gives you access to the most competitive rates.
Can I get a home equity loan if I’m self-employed?
Yes, but it’s more complex. Lenders will typically require two years of tax returns, profit and loss statements, and may scrutinize your income more carefully than they would for a W-2 employee. Make sure your documented income — not just your gross revenue — is strong enough to support the additional debt payment.
The Bottom Line
A home equity loan can be one of the most cost-effective ways to access a large sum of money — especially for homeowners who’ve built substantial equity over the years. The fixed rate, predictable payments, and potentially significant interest savings compared to credit cards make it genuinely useful for the right purpose.
But the stakes are real. Your home is on the line. The smartest approach is to borrow only what you need, have a clear repayment plan before you sign, and shop multiple lenders to ensure you’re getting a competitive rate.

Before you tap your equity, ask yourself: does this use of funds genuinely improve my financial position — or just my current comfort? If the answer is the former, a home equity loan might be exactly the right move.
