If you've owned your home for a few years and property values have risen, you're probably sitting on a meaningful chunk of equity. On a home you bought for $350,000 that's now worth $500,000 with a $250,000 mortgage balance, you have $250,000 in equity—money you can borrow against at rates far lower than credit cards or personal loans. The two main tools for tapping that equity are a Home Equity Line of Credit (HELOC) and a Home Equity Loan. They sound similar, work very differently, and suit different needs.
Choosing the wrong one can cost thousands in interest, expose you to rate shocks, or—worst case—put your home at risk of foreclosure. This guide breaks down how each product works, when each makes sense, and how to decide.
What is a HELOC?
A HELOC is a revolving line of credit secured by your home, structured much like a credit card. You're approved for a maximum credit limit (typically up to 80–85% of your home's value minus your first mortgage), and you can draw against it as needed during the draw period—usually 10 years. You pay interest only on the amount you've actually borrowed. Monthly payments fluctuate based on your balance and the interest rate.
After the draw period ends, you enter the repayment period—usually 15–20 years—during which you can no longer borrow and must pay off the remaining balance, principal plus interest, over the remaining term.
HELOC example
Say you have a home worth $500,000 and a first mortgage balance of $300,000. At 80% LTV, you can borrow up to $100,000 ($500,000 × 80% − $300,000). You're approved for a $100,000 HELOC at Prime + 1% (currently 9.5% with Prime at 8.5%).
You draw $30,000 to renovate a kitchen. Your minimum monthly payment during the draw period is interest only: $30,000 × 9.5% ÷ 12 = $237.50/month. If you pay only interest for 10 years and then repay principal over the next 20, your total cost is enormous—perhaps $50,000+ in interest alone. HELOCs reward disciplined borrowers who pay more than the minimum.
What is a home equity loan?
A home equity loan (sometimes called a second mortgage) is a lump-sum loan with a fixed interest rate and a fixed repayment term—usually 5–30 years. You receive the entire amount up front, make equal monthly payments of principal and interest, and the loan is paid off at the end of the term.
Home equity loan example
Using the same $500,000 home with $300,000 first mortgage, you borrow $50,000 as a home equity loan at 8.25% for 15 years. You receive the full $50,000 at closing. Your monthly payment is fixed at $483.25—every month, for 180 months. Total interest over 15 years is about $37,000. The payment never changes regardless of what happens to interest rates.
HELOC vs home equity loan: side-by-side
| Feature | HELOC | Home Equity Loan |
|---|---|---|
| Funding structure | Revolving credit | Lump sum |
| Interest rate | Variable (Prime + margin) | Fixed |
| Draw period | 10 years typical | None (lump sum at closing) |
| Repayment period | 15–20 years after draw | 5–30 years from start |
| Monthly payment | Variable, often interest-only during draw | Fixed principal + interest |
| Closing costs | $0–$1,000 (often waived) | 2–5% of loan amount |
| Best for | Ongoing or uncertain expenses | One-time known expenses |
| Risk profile | Rate can rise; payment shock at repayment | Fixed; predictable |
Qualification requirements
Both products require equity, decent credit, and sufficient income. Lenders evaluate three primary factors:
Loan-to-value (LTV) and combined LTV (CLTV)
Most lenders cap CLTV (first mortgage + second lien ÷ home value) at 80–85% for HELOCs and 80–90% for home equity loans. A handful of aggressive lenders go to 90–95% but at higher rates and stricter credit requirements. Use our Home Worth Estimator to estimate current value, then calculate CLTV before applying.
Credit score
Most lenders want 680+ for HELOCs and home equity loans. The best rates require 740+. Below 660, options narrow significantly and rates rise.
Debt-to-income (DTI) ratio
Lenders cap DTI (all monthly debt payments ÷ gross monthly income) at 43–50% for second mortgages, depending on the lender and loan type. Add the new HELOC/loan payment to your existing monthly debts and divide by gross income to estimate your post-loan DTI.
When a HELOC makes sense
HELOCs shine when you need flexible access to funds over time, when you're not sure how much you'll need, or when you can repay quickly. Common uses:
- Ongoing home renovations—pay contractors as work progresses, only paying interest on what's drawn
- Emergency reserve—keep a $50,000 HELOC open with $0 balance as a low-cost backup to your emergency fund
- College tuition—draw each semester rather than borrowing a lump sum upfront
- Bridge financing—fund a down payment on a new home before selling the old one (risky but doable)
- Small business cash flow—cover seasonal gaps with a draw, repay when receivables come in
The key advantage: if you don't draw on the line, you pay nothing. A $100,000 HELOC sitting unused costs $0/month—no interest, no payments. This makes it a powerful tool for "just in case" funding.
When a home equity loan makes sense
Home equity loans shine when you have a specific, one-time expense and want payment certainty. Common uses:
- Major renovation with a fixed budget—a $40,000 kitchen remodel with signed contractor quotes
- Debt consolidation—pay off $30,000 in credit card debt at 22% with a home equity loan at 8%
- Large purchase—buying a car, paying for a wedding, covering medical bills
- Investment property down payment—fixed terms make it easier to model rental returns
- Education expenses—when you know the total cost up front
The fixed rate protects you from rising rates, and the fixed payment makes budgeting predictable. If you're worried about variable-rate risk, a home equity loan is the safer choice.
Interest rate dynamics
HELOC rates are variable, tied to the Prime rate (which tracks the federal funds rate). When the Fed raises rates, your HELOC payment rises within 30–60 days. A $50,000 balance at 6% costs $250/month interest-only; the same balance at 9% costs $375/month. If the Fed cuts rates, your HELOC payment falls too.
Home equity loan rates are fixed at origination and don't change for the life of the loan. In a falling-rate environment, you might refinance to lower your rate—but you'll pay closing costs again. In a rising-rate environment, the fixed rate protects you.
Historically, HELOC rates have averaged 1–2% below comparable home equity loan rates because the lender isn't taking rate risk. In 2023–2024, with rates elevated, the spread narrowed—but HELOCs still typically start lower than fixed-rate seconds.
Tax deductibility after the TCJA
The 2017 Tax Cuts and Jobs Act changed the rules for home equity debt. Interest on up to $750,000 of combined mortgage and home equity debt is deductible only if the proceeds are used to buy, build, or substantially improve the home securing the loan. This applies to both HELOCs and home equity loans.
Implications:
- Use HELOC/home equity loan proceeds for renovation → interest is deductible (subject to the $750K cap)
- Use proceeds to pay off credit cards, buy a car, or fund college → interest is not deductible
- Loans originated before December 15, 2017 are grandfathered under the old $1M cap
Keep detailed records of how you used the funds. Commingling deductible and non-deductible uses creates audit headaches. Consult a tax professional before relying on deductibility.
The risk you can't ignore: foreclosure
Both HELOCs and home equity loans are secured by your home. If you stop paying, the lender can foreclose—even if you're current on your first mortgage. Second-lien holders are behind the first mortgage in foreclosure proceeds, so they're more aggressive about pursuing defaults on smaller balances.
Using home equity to pay off unsecured debt (credit cards, personal loans) trades dischargeable debt for non-dischargeable debt secured by your home. If you later face financial hardship, you can't walk away from a home equity loan in bankruptcy the way you can from credit cards. This is the single biggest risk of tapping equity—convert with caution.
Refinancing as a third option
A cash-out refinance replaces your first mortgage with a larger loan and gives you the difference in cash. This often makes sense when:
- Your current first mortgage rate is higher than today's rates
- You want a single payment instead of two
- You need more than 85% LTV (cash-out refinances go to 80% LTV on conventional)
Cash-out refinance closing costs are higher (2–5% of total loan amount, not just the cash), but the rate is usually lower than a HELOC or home equity loan. Compare using our Refinance Calculator—sometimes a cash-out refinance beats both second-lien options.
HELOC conversion features
Many modern HELOCs offer a "fixed-rate advance" option that lets you lock all or part of your variable-rate balance into a fixed-rate sub-loan within the line. This hybrid appeals to borrowers who want HELOC flexibility for drawing but fixed-rate certainty for repayment. A typical scenario: draw $50,000 at variable Prime + 1% to fund a renovation, then convert that $50,000 to a fixed 7.5% rate with a 15-year repayment schedule. You keep the remaining credit line variable for future draws.
Not all HELOCs offer conversion, and terms vary. Some charge a conversion fee ($50–$500), limit how often you can convert (annually, typically), or require a minimum balance to convert. Read the HELOC agreement carefully before relying on this feature. If rate certainty is essential from day one, a home equity loan is the cleaner choice; if you want flexibility with a fixed-rate escape hatch, a convertible HELOC may suit you better.
Common mistakes to avoid
- Using a HELOC like free money. Interest-only payments during the draw period are seductive but dangerous. Without disciplined repayment, you enter the repayment period with the full balance—and a payment that can double or triple.
- Treating your home like an ATM. Repeatedly tapping equity to fund lifestyle spending erodes the wealth-building power of homeownership. Reserve equity for investments that build value: renovations, education, business.
- Ignoring rate risk on HELOCs. A HELOC at 5% can become 9% in 18 months. If you can't afford the payment at +3%, don't take the line.
- Borrowing more than you need with a home equity loan. A lump sum tempts spending what you don't need. If you're not sure of the total cost, choose a HELOC and draw only what's required.
- Forgetting closing costs. HELOCs often waive closing costs but charge early-closure fees if you close the line within 2–3 years. Home equity loans charge 2–5% in closing costs—budget for them.
- Skipping the appraisal. Some HELOCs use automated valuations; home equity loans almost always require full appraisals. A low appraisal can shrink your credit limit or kill the loan.
Frequently asked questions
Can I have both a HELOC and a home equity loan?
Yes, but most lenders won't extend both simultaneously on the same property, and total CLTV caps still apply. If you have a HELOC and want a fixed-rate portion, ask about a "fixed-rate advance" feature—some HELOCs let you lock in a fixed rate on a portion of your balance while keeping the rest variable.
What happens to a HELOC when I sell the house?
The full outstanding balance must be paid off at closing from sale proceeds. Your title company handles this automatically. Plan for it—failure to disclose the HELOC to your closing agent can delay or kill the sale.
Can a HELOC be frozen?
Yes. Lenders can freeze or reduce a HELOC if your home value declines significantly, your credit score drops, or you miss payments on other debts. This happened widely during the 2008–2010 housing crash. Don't rely on a HELOC as your only emergency fund.
Are HELOC rates tax deductible?
Only if the proceeds are used to buy, build, or substantially improve the home securing the loan, and your total mortgage debt is under the $750,000 cap. See IRS Publication 936 or consult a tax professional.
Which is better for debt consolidation?
A home equity loan's fixed rate and payment make it safer for debt consolidation—you know exactly when you'll be debt-free. A HELOC's variable rate can rise and undo your savings. Either way, fix the spending behavior that created the debt, or you'll be back in the same place with a fresh lien on your home.
