What Is a Home Equity Loan?
A home equity loan is a second mortgage that allows homeowners to borrow against the equity built up in their property. The loan delivers a single lump sum at closing with a fixed interest rate and a fixed monthly payment schedule over a defined term, typically 5 to 30 years. Because the loan is secured by the home, interest rates are substantially lower than unsecured personal loans or credit cards.
The home equity loan is sometimes called a "second mortgage" because in most cases there is an existing first mortgage, and the home equity loan occupies a junior lien position. In the event of foreclosure, the first mortgage lender is paid first from any sale proceeds; the home equity lender receives payment only from remaining funds.
How It Works
Lump sum disbursement: Unlike a HELOC, which functions as a revolving credit line, a home equity loan delivers the full approved amount at closing. The borrower does not have the ability to redraw repaid principal.
Fixed rate and payment: The interest rate is set at closing and does not change over the loan term. Monthly payments are fully amortizing—each payment covers both interest and principal, with the loan fully repaid at term end. This predictability makes home equity loans attractive for borrowers who want certainty in their monthly payment obligations.
Loan term: Terms typically range from 5 to 30 years, with 10 and 15 years being common. Shorter terms reduce total interest paid but increase monthly payments. Longer terms lower monthly payments but increase total interest cost over the loan life.
Closing costs: Home equity loans carry closing costs, typically 2–5% of the loan amount, covering origination fees, appraisal, title, and other charges. Some lenders offer "no closing cost" home equity loans in exchange for slightly higher rates.
Credit Limit and Equity Requirements
The maximum borrowing amount is constrained by the home's value and the existing first mortgage balance. Lenders compute the combined loan-to-value (CLTV) ratio:
CLTV = (First Mortgage Balance + Home Equity Loan) / Appraised Value
Most lenders cap CLTV at 80–85%, though some allow up to 90% for well-qualified borrowers. The calculation:
Max Home Equity Loan = (Appraised Value × Max CLTV%) − First Mortgage Balance
On a $400,000 home with a $220,000 first mortgage at 80% CLTV:
- Maximum combined debt: $400,000 × 0.80 = $320,000
- First mortgage: $220,000
- Maximum home equity loan: $100,000
Home Equity Loan vs. HELOC vs. Cash-Out Refinance
Three primary vehicles exist for extracting home equity. The optimal choice depends on the borrower's needs, market rates, and existing mortgage:
Home equity loan: Best when the borrower has a specific, defined need and wants payment certainty. Preserves the existing first mortgage. Fixed rate eliminates rate risk. Suitable for a one-time expense like a renovation or debt consolidation.
HELOC: Best for ongoing or uncertain funding needs where the borrower wants draw flexibility. Variable rate carries rate risk in rising-rate environments. Draw period payments are interest-only, which lowers short-term cost but defers principal repayment.
Cash-out refinance: Best when the existing first mortgage rate is at or above current market rates, making a complete replacement advantageous. Replaces the first mortgage entirely with a new loan at the current rate. Incurs full refinance closing costs. More appropriate when the equity need coincides with a rate reduction opportunity.
In a low-rate first mortgage environment, a home equity loan preserves the valuable existing rate while accessing equity. Replacing a below-market first mortgage with a cash-out refinance at a higher rate to access equity is often economically inferior.
Common Uses
Renovation and home improvement: Large-scale projects—kitchen remodels, additions, roof replacements, HVAC systems—are well-suited to a home equity loan because the cost is known upfront and the lump sum matches the funding need. See AI tools for homeowners renovation design for planning support.
Debt consolidation: High-rate consumer debt (credit cards, personal loans) can be consolidated into a lower-rate home equity loan. The risk is converting unsecured debt into a mortgage lien; failure to service the consolidated loan puts the home at risk.
Major one-time expenses: Education, medical costs, and other large-but-defined expenses match the lump-sum structure of a home equity loan.
Real estate investment: Investors sometimes use home equity loans on a primary residence or existing investment property to fund down payments or purchase prices on additional properties.
Risk Considerations
Home equity loans add to total mortgage debt and reduce the equity cushion protecting the homeowner in case of value decline. A borrower who takes out a large home equity loan shortly before a market downturn may find themselves with combined debt exceeding their home's value, limiting their ability to sell or refinance.
The fixed payment obligation must be met regardless of income changes. Unlike a HELOC (which allows interest-only minimum payments during the draw period), the home equity loan requires principal-and-interest payments from the first month. Borrowers should stress-test affordability against potential income disruptions.
Common Misconceptions
Home equity loans are the same as HELOCs. The terms are sometimes used interchangeably in casual usage, but they are structurally distinct products. A home equity loan is a closed-end, fixed-rate, lump-sum loan; a HELOC is an open-end revolving credit facility.
You need perfect credit to qualify. While strong credit improves terms, most lenders approve home equity loans at credit scores of 620 and above. Equity, income, and DTI are also significant factors in approval decisions.
The deduction makes home equity loans always tax-advantaged. Post-2017 tax law restricts the interest deduction to qualified home improvement uses. For other purposes, there is no deduction advantage over other borrowing forms.
