HELOC vs. Home Equity Loan: Key Differences Explained

Two Paths Into Your Home's Value

American homeowners held a combined $11.5 trillion in tappable home equity as of early 2024, according to Black Knight data. Two products dominate the market for accessing that wealth: the home equity line of credit (HELOC) and the home equity loan. They share a common collateral — your house — but differ in structure, risk profile, and cost in ways that matter enormously over a decade of repayment.

How a HELOC Works

A HELOC is a revolving credit line secured by your home. The lifecycle has two distinct phases. The draw period typically runs 10 years, during which you can borrow, repay, and reborrow up to your credit limit. Many lenders require interest-only payments during this phase, which keeps monthly costs low but leaves principal untouched. After the draw period closes, the repayment period begins — usually 20 years — and full principal-plus-interest payments kick in. That payment reset can shock borrowers who only budgeted for the interest phase.

HELOC rates are almost always variable, tied to the prime rate (currently the federal funds rate plus 3%). When the Fed raised rates 525 basis points between March 2022 and July 2023, HELOC holders saw their rates surge in lockstep. Some lenders cap the lifetime rate increase at 18%, but even a 400 basis-point increase on a $100,000 HELOC adds $333 per month in interest.

HELOC Freeze Risk

Lenders can freeze or reduce a HELOC if your home value drops, your creditworthiness deteriorates, or the lender faces its own financial stress. During the 2008–2009 housing crisis, major banks including JPMorgan Chase and Countrywide froze hundreds of thousands of HELOC lines. Borrowers who relied on the line for planned expenses — a home renovation mid-project, for instance — were stranded. Federal law (12 CFR Part 226) permits freezes under these conditions; lenders must give written notice within three business days.

How a Home Equity Loan Works

A home equity loan delivers a single lump sum at closing, repaid over a fixed term (typically 5 to 30 years) at a fixed interest rate. There is no draw period — you receive all the money upfront and start repaying immediately. This structure suits borrowers with a defined, one-time need: a roof replacement, debt consolidation, or college tuition payment.

Fixed rates provide certainty. If you borrow $80,000 at 8.5% for 15 years, your payment is exactly $787.84 per month every month until payoff, regardless of what the Fed does. That predictability costs something — fixed rates typically run 0.25 to 0.75 percentage points higher than the initial rate on a comparable HELOC in a stable rate environment.

The CLTV Limit: How Much Can You Borrow?

Both products are governed by the combined loan-to-value (CLTV) ratio — the total of your existing mortgage balance plus the new equity product, divided by your home's appraised value. Most lenders cap CLTV at 85%. A home worth $400,000 with a $250,000 mortgage balance leaves a maximum combined debt of $340,000, so the equity product cannot exceed $90,000.

Some credit unions extend CLTV to 90% or even 100%, but rates climb sharply above 85% to compensate for lender risk. A 90% CLTV product on a falling-value property can quickly go underwater if prices decline 10%.

Tax Deductibility Rules

The Tax Cuts and Jobs Act of 2017 (TCJA) fundamentally changed home equity interest deductibility. Interest on both HELOCs and home equity loans is deductible only if the proceeds are used to buy, build, or substantially improve the home securing the debt. The IRS formalized this in Notice 2018-32.

• Using a HELOC to remodel your kitchen: interest is deductible (acquisition debt)
• Using a HELOC to pay off credit cards: interest is not deductible (personal use)
• Using a home equity loan to fund a vacation: not deductible
• Total mortgage debt eligible for the deduction caps at $750,000 for loans originated after December 15, 2017 ($1 million for older loans)

Borrowers must itemize deductions on Schedule A to claim the benefit. Given the TCJA's higher standard deduction ($29,200 for married filing jointly in 2024), fewer taxpayers benefit even when the use qualifies.

Side-by-Side Comparison

Choosing Between Them

The choice reduces to two questions: Do you know exactly how much you need? And how much rate risk can you absorb?

• Choose a HELOC if you need flexible access over time — funding a multi-year renovation, having an emergency buffer, or managing a business with variable cash needs. Accept that rising rates will raise your cost.
• Choose a home equity loan if you have a specific, known expense and want payment certainty. The higher initial rate is the price of that certainty.
• Consider neither if you plan to sell within 3 years — closing costs (typically 2–5% of the loan) eat into any savings, and proceeds must repay both obligations at closing.

Many borrowers overlook a third alternative: downsizing. Selling a $600,000 home and buying a $400,000 replacement unlocks $200,000 in equity with no ongoing debt obligation, no CLTV limit, and no freeze risk. The calculus depends on transaction costs, relocation willingness, and life stage — but it deserves a place in any equity-access analysis.
