Once you have built equity in your home, you can borrow against it with a second mortgage, either a home equity loan or a home equity line of credit (HELOC). Both use your home as collateral, but they work very differently in how you receive and repay the money. Choosing the right one depends on whether you need a fixed lump sum or flexible, ongoing access.
How a home equity loan works
A home equity loan gives you a single lump sum upfront, repaid in fixed monthly installments over a set term, usually at a fixed interest rate. Because the rate and payment are fixed, budgeting is predictable, much like your primary mortgage. This structure suits a one-time expense with a known cost, such as a major renovation or debt consolidation. You start paying principal and interest immediately on the full amount borrowed.
How a HELOC works
A HELOC is a revolving line of credit you can draw from as needed during a draw period, often ten years, similar to a credit card secured by your home. During the draw period you may pay interest only on what you have borrowed, and the rate is usually variable, so payments can rise. After the draw period ends, the line enters a repayment period where you pay back principal and interest, and the payment can jump substantially. HELOCs suit ongoing or uncertain costs where you want flexibility.
Comparing the trade-offs
A home equity loan offers rate certainty and a clear payoff schedule but locks in the full amount and its interest from day one. A HELOC offers flexibility and interest only on what you use, but variable rates make future payments unpredictable and the repayment-period jump can strain budgets. Lenders typically let you borrow up to a combined loan-to-value ratio of around 80% to 85%, counting your first mortgage plus the new debt. Your choice hinges on whether you value predictability or flexibility.
The risk you cannot ignore
Both options are secured by your home, which means defaulting can lead to foreclosure just like your primary mortgage. Borrowing against equity turns your house into collateral for what may be discretionary spending, so the stakes are high. Interest may be tax-deductible only when the funds are used to buy, build, or substantially improve the home, under current tax rules. Treat a second mortgage as seriously as the first, because the same asset is on the line.
You have $200,000 of equity and need $50,000 for a renovation. A home equity loan hands you $50,000 at a fixed 8%, with steady payments over 15 years. A HELOC instead approves a $50,000 line at a variable rate, and you draw only as contractors bill you, paying interest on the drawn balance until the draw period ends and repayment begins.
Key takeaways
- A home equity loan is a fixed-rate lump sum with predictable payments.
- A HELOC is a variable-rate revolving line you draw from during a set draw period.
- Home equity loans suit one-time known costs; HELOCs suit ongoing or uncertain needs.
- Lenders usually cap combined loan-to-value around 80% to 85% across both mortgages.
- Both use your home as collateral, so default can lead to foreclosure.
Common mistakes
- Choosing a HELOC for its low interest-only payments without planning for the repayment-period jump.
- Borrowing against home equity for discretionary spending and putting the house at risk.
- Assuming HELOC interest is always tax-deductible, when it generally is not unless used to improve the home.
FAQ
Can I have a HELOC and a home equity loan at the same time?
Potentially, if your combined loan-to-value stays within the lender's limit, usually around 80% to 85%. Your total borrowing across the first mortgage and any second liens must fit under that cap.
Which has lower closing costs?
HELOCs often have low or no closing costs, while home equity loans may carry costs closer to a mortgage. Compare offers, since terms vary widely by lender.
