HELOC Explained: How Home Equity Lines of Credit Work
How a HELOC Works: Two Phases
| Phase | Duration | What Happens |
|---|---|---|
| Draw period | 5–10 years | Borrow up to your limit, make interest-only payments (minimum). Can repay and reborrow freely. |
| Repayment period | 10–20 years | No more borrowing. Pay back principal + interest in fixed monthly installments. |
During the draw period, most HELOCs require only interest payments on what you’ve borrowed. This means low monthly costs while you have access to funds — but be aware that payments jump significantly when the repayment period starts and you begin paying principal.
HELOC Key Terms
| Feature | Details |
|---|---|
| Rate type | Variable (tied to prime rate + margin) |
| Typical APR | 7–12% (varies with prime rate) |
| Credit limit | Up to 80–85% of home equity |
| Draw period | 5–10 years |
| Repayment period | 10–20 years |
| Minimum payment (draw period) | Interest only on outstanding balance |
| Annual fee | $0–$75 (some lenders) |
| Tax deductible | Yes — if used for home improvements |
HELOC vs. Home Equity Loan
| Factor | HELOC | Home Equity Loan |
|---|---|---|
| Rate | Variable | Fixed |
| Access to funds | Draw as needed (revolving) | Lump sum at closing |
| Interest paid on | Only what you borrow | Full loan amount |
| Monthly payments | Vary with balance and rate | Fixed, predictable |
| Best for | Ongoing expenses, uncertain costs | One-time large expense |
| Rate risk | Payments rise if rates increase | No rate risk |
Best Uses for a HELOC
Home renovations are the sweet spot — especially phased projects where costs unfold over months. You draw what you need when you need it, pay interest only on what’s outstanding, and the interest may be tax-deductible.
A HELOC can also serve as an emergency backup credit line — better than credit cards at 20%+ APR. Some homeowners maintain a HELOC with zero balance as a financial safety net alongside their emergency fund.
Payment Shock: The Repayment Phase Trap
The biggest HELOC risk isn’t the variable rate — it’s the transition from draw to repayment period. During the draw period, minimum payments are interest-only. When repayment starts, you suddenly owe principal + interest. On a $50,000 HELOC balance at 8%, monthly payments can jump from $333 (interest only) to roughly $580 (fully amortizing over 15 years). Plan for this from day one.
Key Takeaways
- A HELOC is a revolving credit line secured by your home with a draw period (5–10 years) and repayment period (10–20 years).
- You pay interest only on what you borrow — not the full credit limit.
- Variable rates mean your payments can increase; stress-test your budget for a 3% rate hike.
- Best for phased home improvements or as an emergency backup line — not for discretionary spending.
- Make principal payments during the draw period to avoid “payment shock” when repayment begins.
Frequently Asked Questions
Can I convert a HELOC to a fixed rate?
Some lenders offer a fixed-rate lock option that converts part or all of your HELOC balance to a fixed rate. This eliminates rate risk on the locked portion. Ask about this feature when shopping — it provides the flexibility of a HELOC with the stability of a home equity loan.
What happens if I sell my house with a HELOC?
The HELOC balance must be paid in full at closing, just like your primary mortgage. The proceeds from the sale pay off both loans. If the sale price doesn’t cover both balances, you’d need to bring cash to closing.
Can I use a HELOC for debt consolidation?
You can, and the lower interest rate (vs. credit cards) saves money. But you’re converting unsecured debt into debt secured by your home — if you can’t repay, you could lose your house. Make sure you have a budget in place to prevent running up new credit card debt after consolidating.
Is there a minimum draw amount on a HELOC?
Most HELOCs have a minimum initial draw (often $10,000–$25,000) and minimum subsequent draws ($300–$500). Some have no minimum after the initial draw. Check your lender’s terms — you don’t want to borrow more than you need just to meet a minimum.
What credit score do I need for a HELOC?
Most lenders require 680+ for a HELOC, though some accept 620+. Higher scores (720+) get the best rates and highest credit limits. Your debt-to-income ratio and available equity also factor into approval and terms.
