A lot of that equity gets accessed through a HELOC. It's a flexible way to borrow against your home for renovations, debt consolidation, or a financial cushion.
This guide walks through how a HELOC actually works, what it costs, how to qualify, and when it makes sense versus other options.
Key Takeaways
- HELOCs give revolving access to home equity—secured by your house, with limits far larger than a typical credit card.
- A draw period allows interest-only payments; a repayment period requires principal plus interest.
- Rates usually track the prime rate and stay variable, though some lenders offer fixed-rate options.
- Approval hinges on equity stake, credit score, and debt-to-income ratio.
What Is a HELOC and How Does It Work?
A HELOC is a revolving line of credit secured by the equity in your home. Because your house backs the loan, lenders treat it as a second mortgage — a second lien sitting behind your primary mortgage, according to the CFPB.
Your available equity is simple math: home value minus what you still owe on your mortgage. If your home is worth $500,000 and you owe $300,000, you're sitting on $200,000 in equity. Lenders won't let you borrow all of it. Most cap combined loan-to-value around 80%–85%, so only part of that equity becomes available credit.
The Draw Period
This is the borrowing phase. You can pull funds through checks, a linked card, or transfers, up to your credit limit. Payments during this stretch are typically interest-only, and the CFPB uses 10 years as a common example length.
The Repayment Period
Once the draw period ends, borrowing stops. You move into repayment, where you owe both principal and interest. The CFPB notes this phase often runs 10 to 15 years, though some lenders build in a balloon payment instead.
Risks and Consumer Protections
Because your home secures the debt, missed payments can lead to foreclosure. That collateral risk is the trade-off for rates that usually beat unsecured credit.
If the HELOC is secured by your primary residence, you get a three-business-day right to cancel, for any reason, without penalty. This rescission window doesn't apply to vacation or second homes.
HELOC Interest Rates and Costs
Most HELOCs carry a variable rate, calculated as the prime rate plus a lender margin. As of late August 2026, the national average HELOC rate sat at 7.30%, based on Bankrate's survey of major home-equity lenders.
Bankrate's example pairs a 6.75% prime rate with a 3% margin, landing at a 9.75% rate. Your actual margin depends on your credit profile and the lender.
Some lenders let you lock in a fixed rate on part or all of your balance for predictable payments. Ask about this option if rate swings make you nervous.
Fees to budget for:
- Application fees: $15–$75, or up to 4.99% of your credit line
- Appraisal fees: charged to confirm your home's current value
- Annual fees: typically $5–$250
- Early closure fees: apply if you pay off and close the line within the first few years
Qualifying for a HELOC
Lenders look at three main factors before approving a HELOC.
Equity requirement. Most lenders want you to keep at least 20% equity after counting your existing mortgage plus the new line—typically a combined loan-to-value (CLTV) of 80% or less. Some will accept as little as 15% remaining equity.
Credit score. Requirements vary by lender:
- Bankrate reports many lenders accept scores in the 600s, with 620 as a common baseline
- Experian cites a more conservative benchmark: 680 or higher
- myFICO notes second mortgages typically look for 620+
Debt-to-income ratio. Most lenders cap DTI around 36%, though some stretch to 45% or 50% depending on other factors like reserves and equity.
Already have a mortgage? That's not a disqualifier. A HELOC sits as a second lien behind your existing mortgage, and lenders evaluate your combined loan-to-value ratio, not just your first mortgage balance.
When you apply, lenders typically ask for paperwork that verifies income, the existing mortgage, and property protections:
- Proof of income (pay stubs, tax returns)
- Current mortgage statement
- Proof of property tax and homeowners insurance payments
Pros and Cons of a HELOC
| Pros | Cons |
|---|---|
| Borrow only what you need, when you need it | Variable rate means payments can rise |
| Interest-only payments during the draw period | Your home is collateral — missed payments risk foreclosure |
| Often lower rates than credit cards | Payment shock when repayment period begins |
| Interest may be tax-deductible for home improvements | Fees add up (application, annual, early closure) |
That tax break is limited. The IRS allows a deduction only when HELOC funds go toward buying, building, or substantially improving the home that secures the loan, and only if you itemize.
Interest used to pay off credit cards or cover living expenses doesn't qualify. The debt limit for deductibility is $750,000 ($375,000 if married filing separately), per IRS Publication 936.
Common Uses and Alternatives
Homeowners typically tap a HELOC for:
- Home renovations and repairs
- Debt consolidation (rolling high-interest credit card debt into a lower-rate line)
- Education costs
- Emergency expenses
- Large purchases such as a vehicle or major appliance
One common misconception: you can't use a HELOC to buy a house directly. A HELOC draws against equity in a home you already own, so it's not structured as purchase financing unless you're borrowing against a different property you already hold.
HELOC vs. Home Equity Loan
The other main way to tap equity is a home equity loan. The difference comes down to structure:
- HELOC: Revolving credit, draw repeatedly up to your limit, usually variable rate
- Home equity loan: One lump sum upfront, fixed or adjustable rate, fixed repayment schedule
- Cash-out refinance: Replaces your current mortgage with a larger loan and pays the difference in cash; one new payment, often a fixed rate
If your need is ongoing or uncertain in amount, a HELOC's flexibility fits better. If you know exactly what you need, a lump-sum home equity loan might simplify things. If you also want to reset your first mortgage rate or term while pulling equity, a cash-out refinance may be the cleaner path.
Before you choose among a HELOC, a home equity loan, or a cash-out refinance, walk through equity, income, and timeline with a mortgage advisor. ClearPoint Mortgage Advisors works with homeowners on that full picture—property value, budget, and goals—and helps determine which equity-access option actually fits.
Frequently Asked Questions
How do you repay a HELOC?
During the draw period, you pay interest only. Once repayment begins, monthly payments cover both principal and interest, typically spread over 10 to 20 years.
What happens at the end of a HELOC draw period?
Borrowing stops and the repayment period starts. Monthly payments increase since you're now paying down principal along with interest.
Can you withdraw cash from a HELOC?
Yes. You can typically access funds through checks, a linked debit or credit card, or an online transfer, up to your approved credit limit.
Can you get a HELOC if you already have a mortgage?
Yes. A HELOC becomes a second lien behind your existing mortgage. Lenders assess your combined loan-to-value ratio across both loans, not just your first mortgage.
Can you use a HELOC to buy a house?
Generally, no. A HELOC is secured by a home you already own, so it fits renovations, consolidation, or other expenses better than a new purchase. The exception is when it's secured against a separate property you already hold.
