A HELOC lets you borrow against your home equity as needed — like a credit card secured by your house, but at a fraction of the interest rate. This guide covers how HELOCs work, what they cost, who qualifies, and when a HELOC is (and isn’t) the right choice.
What Is a HELOC?
| Feature | HELOC | Home Equity Loan | Cash-Out Refinance |
|---|---|---|---|
| Type | Revolving credit line | Fixed lump sum | New mortgage |
| Rate | Variable | Fixed | Fixed (usually) |
| Draw period | Set by lender (10 years, for example) | None | None |
| Repayment | Set by lender, often over ten or more years after the draw period | Set by lender | New mortgage term |
| Access | Draw as needed | One-time | One-time |
| Closing costs | Some lenders waive some or all | Varies by lender | Generally higher than a HELOC |
| Interest-only option | Yes (during draw period) | No | No |
How Much Can You Borrow?
Lenders set a maximum combined loan-to-value (CLTV), and it varies by lender. The table shows what 80% and 90% would allow:
| Home Value | Existing Mortgage | Available Equity (80% CLTV) | Available Equity (90% CLTV) |
|---|---|---|---|
| $300,000 | $200,000 | $40,000 | $70,000 |
| $400,000 | $250,000 | $70,000 | $110,000 |
| $500,000 | $300,000 | $100,000 | $150,000 |
| $600,000 | $350,000 | $130,000 | $190,000 |
| $750,000 | $400,000 | $200,000 | $275,000 |
Formula: (Home Value × CLTV %) - Existing Mortgage Balance = HELOC Limit
Current HELOC Rates (October 2026)
Your HELOC rate is the prime rate plus or minus a margin your lender sets. The prime rate was 7.00% as of October 13, 2026. Lenders price the margin by credit score, loan-to-value and other factors, and they change it often, so this guide doesn’t list a rate by credit tier. Ask each lender for its margin, its introductory rate (if any) and what the rate becomes afterward.
| Component | Value |
|---|---|
| Prime rate (October 13, 2026) | 7.00% |
| Margin | Set by the lender |
| Your HELOC rate | Prime + margin |
HELOC rates move with the prime rate.
HELOC Payment Examples
During the draw period (interest-only):
| Balance | Rate | Monthly Interest-Only Payment |
|---|---|---|
| $25,000 | 7.0% | $146 |
| $50,000 | 7.0% | $292 |
| $75,000 | 7.0% | $438 |
| $100,000 | 7.0% | $583 |
| $150,000 | 7.0% | $875 |
During the repayment period (principal + interest, 20-year):
| Balance | Rate | Monthly P&I Payment |
|---|---|---|
| $25,000 | 7.0% | $194 |
| $50,000 | 7.0% | $388 |
| $75,000 | 7.0% | $581 |
| $100,000 | 7.0% | $775 |
| $150,000 | 7.0% | $1,163 |
Examples use 7.0%, about the prime rate as of October 13, 2026 (a zero margin), for illustration only.
Payment shock warning: When the draw period ends, your payment can rise as principal repayment begins. In these examples it goes up about 33% (for instance from $583 to $775 on $100,000).
Qualification Requirements
Each lender sets its own minimums, so ask for them before you apply. They generally look at:
- Credit score and history
- Combined LTV and the equity you keep in the home
- Debt-to-income ratio: different loan products and lenders have different DTI limits, according to the CFPB
- Verified income and employment history
- Property type: usually your primary residence; some lenders allow second homes
HELOC Phases
| Phase | Duration | What Happens | Payment Type |
|---|---|---|---|
| Draw period | Set by lender; 10 years, for example | Borrow, repay, re-borrow up to limit | Interest-only (minimum) |
| Repayment period | Set by lender; often over ten or 20 years | No new borrowing, pay down balance | Principal + interest |
Best Uses for a HELOC
| Use Case | Good Idea? | Why |
|---|---|---|
| Home renovations | ✅ | Adds value, may be tax-deductible |

| Day-to-day expenses | ❌ No | Sign of living beyond means |
Tax Deductibility
HELOC interest is tax-deductible IF proceeds are used to “buy, build, or substantially improve” the home:

| New roof or HVAC | ✅ Yes | Substantial improvement |
| Home addition | ✅ Yes | Building onto the home |
| Debt consolidation | ❌ No | Not home improvement |

Comparing HELOC Lenders
This page does not rank lenders or list their terms, because rates, fees and minimum draws change often and are set by each lender. Ask every lender for the same things in writing: the margin over prime, any introductory rate and what it becomes afterward, the rate cap, and the fee schedule. HELOCs are priced as prime plus or minus a margin; prime was 7.00% as of October 13, 2026.
How to Choose a HELOC Lender
| Factor | What to Look For |
|---|---|
| Interest rate | Compare APR, not just advertised rate — factor in margin over prime |
| Closing costs | Some lenders waive some or all up-front costs; others charge fees |
| Annual fee | Ask whether an annual or maintenance fee applies, even if you don’t use the line |
| Fixed-rate option | Some lenders let you lock a fixed rate on part of your balance |
| Draw period length | Set by lender; 10 years, for example |
| Early closure fee | Ask whether you owe a fee or waived costs if you close the line early |
| Minimum draw | Some plans require a minimum amount each time you borrow |

HELOC Application Process
Applying for a HELOC is similar to applying for a mortgage, and the timeline depends on the lender.
Steps to Apply
| Step | Timeline | What’s Needed |
|---|---|---|
| 1. Check credit score | Before applying | Pull free report at AnnualCreditReport.com |
| 2. Estimate home value | Before applying | Zillow/Redfin estimate, or get appraisal |
| 3. Calculate available equity | Before applying | (Home value × CLTV%) − Mortgage balance |
| 4. Compare lenders | Before applying | Rate, fees, draw period, minimum draw |
| 5. Submit application | Day 1 | Tax returns, pay stubs, mortgage statement |
| 6. Home appraisal | Varies | Lender orders it; you may pay a fee |
| 7. Underwriting review | Varies | Lender verifies income, credit, property value |
| 8. Closing | 1 day | Sign documents; 3-day right of rescission |
| 9. Access funds | After the rescission period | Draw period begins |
Total timeline: varies by lender; ask yours for an expected closing date.
Documents Required
| Document | Purpose |
|---|---|
| 2 years federal tax returns | Income verification |
| 2 most recent pay stubs | Employment and current income |
| Most recent mortgage statement | Existing lien documentation |
| Proof of homeowner’s insurance | Required at closing |
| Government-issued ID | Identity verification |
| Bank statements (2-3 months) | Asset verification |
Managing HELOC Rate Risk
Because HELOCs use variable rates tied to the prime rate, your payment can change significantly when the Fed raises or cuts rates. In 2022-2023, the prime rate rose from 3.25% to 8.5% — borrowers with $100,000 HELOC balances saw monthly interest payments jump from $271 to $708.
Strategies to Manage Rate Risk
| Strategy | How It Works | Best For |
|---|---|---|
| Fixed-rate lock | Some lenders let you lock a portion of your balance at a fixed rate | Large, specific-expense draws |
| Pay down principal aggressively | Reduce balance during draw period to lower payment risk | Conservative borrowers |
| HELOC to home equity loan refinance | Convert variable balance to fixed-rate loan | When rates are rising |
| Cash-out refinance | Replace variable HELOC with new fixed first mortgage | High HELOC balance relative to home value |
| Rate monitoring | Set alerts for Fed rate decisions | Everyone with a HELOC |
Quick Reference Table

| Draw period | Set by lender; 10 years, for example (borrow as needed) |
| Repayment period | Set by lender; often over ten or 20 years |
| Min credit score | Set by lender |
| Min equity | Set by lender |
| Closing costs | Varies; some lenders waive some or all |
| Tax deductible? | Only if used for home improvement |
| Max borrowing | Lender’s CLTV limit minus mortgage balance |
The Bottom Line
A HELOC is one of the cheapest ways to borrow money — but it turns unsecured debt into debt secured by your home. Use it for home improvements (which add value and may be tax-deductible) or as an emergency backstop. Never use it for vacations, everyday spending, or speculative investments. If you need a fixed amount for a known expense, a home equity loan may be simpler. If your current mortgage rate is high (7%+), a cash-out refinance may give you a better single-rate deal. Always compare all three options before deciding. Use the free home equity calculator to model your specific situation, and consider consulting a HUD-approved housing counselor if you’re unsure about the impact on your overall financial picture.
