What is a HELOC (Home Equity Line of Credit)
A HELOC (Home Equity Line of Credit) is a revolving line of credit secured by your home's equity — working similarly to a credit card, allowing you to borrow, repay, and reborrow up to a set limit during the draw period.
A HELOC (Home Equity Line of Credit) is a type of revolving credit that uses your home equity as collateral. Unlike a home equity loan (which delivers a lump sum), a HELOC works like a credit card — you're approved for a maximum credit limit and can draw from it as needed, repay it, and draw again during the draw period.
HELOCs are popular for home renovations, large expenses spread over time, and emergency funds because they offer flexibility — you only pay interest on what you actually borrow, not the entire credit line.
How a HELOC Works
A HELOC has two distinct phases:
Draw Period (typically 5–10 years)
During this phase, you can borrow money up to your credit limit at any time. You're typically required to make interest-only payments on the outstanding balance. Your monthly payment fluctuates based on how much you've borrowed and the current interest rate (most HELOCs have variable rates).
Repayment Period (typically 10–20 years)
The credit line closes, and you can no longer draw. Your outstanding balance converts to a fully amortized loan — meaning monthly payments now include both principal and interest. For borrowers who borrowed heavily during the draw period, this transition can significantly increase their monthly payment — a phenomenon known as "payment shock."
HELOC Interest Rates
Most HELOCs have variable interest rates tied to the prime rate (the benchmark rate set by major U.S. banks, which tracks the federal funds rate). When the Federal Reserve raises rates, your HELOC rate rises. When rates fall, the rate drops.
Some lenders offer a fixed-rate option that lets you convert all or part of the outstanding balance to a fixed rate — useful if you want payment predictability on a large draw.
How Much Can You Borrow?
HELOCs are generally limited to 80–85% of your home's value, minus your existing mortgage balance.
Example:
- Home value: $500,000
- Existing mortgage: $240,000
- Maximum HELOC (at 80% LTV): ($500,000 × 0.80) − $240,000 = $160,000 credit line
Lenders also evaluate your credit score, income, and debt-to-income ratio before approving the line.
HELOC vs. Home Equity Loan vs. Cash-Out Refinance
| HELOC | Home Equity Loan | Cash-Out Refi | |
|---|---|---|---|
| Funds access | Revolving line | Lump sum | Lump sum at closing |
| Rate type | Variable (usually) | Fixed | Fixed or ARM |
| Monthly payment | Interest-only during draw | Fixed | Fixed (PITI) |
| Affects first mortgage | No | No | Yes — replaces it |
| Best for | Ongoing/flexible expenses | One-time large expense | Large sum + rate improvement |
Uses and Risks
Common uses:
- Home renovations and additions (can increase home value)
- Education expenses
- Emergency fund backup (open a HELOC when your credit is strong, don't use it unless needed)
- Bridging financing between selling one home and buying another
Risks:
- Your home is the collateral — failure to repay can lead to foreclosure
- Variable rates mean payments can increase significantly if the Fed raises rates
- During the repayment period, higher payments can strain cash flow
- "Available credit" temptation — borrowing against equity for non-essential expenses can erode wealth
A HELOC is generally best for disciplined borrowers who have a specific, well-defined plan for the funds and the financial cushion to handle potential rate increases.
