Home Equity Loan

A home equity loan is a fixed-rate second mortgage secured by the borrower’s equity in a primary residence. The lender advances a lump sum based on appraised home value minus outstanding mortgage balance, and the borrower repays in fixed installments over a set term, typically 5–20 years.

Why fixed-rate structure matters

The defining feature of a home equity loan is its fixed interest rate and payment schedule. Unlike a floating-rate bond or adjustable-rate mortgage, the borrower knows the exact payment for the life of the loan. This certainty appeals to risk-averse borrowers and those with tight cash flow. Interest rate increases will never raise your payment. Conversely, if rates fall dramatically, you cannot benefit from refinancing a fixed-rate equity loan without taking out a new one (incurring closing costs). The fixed structure also lends clarity to household budgeting; payments are as predictable as utility bills.

The equity calculation and borrowed amount

A home equity loan is available to homeowners with proven equity—the difference between the home’s current market value and any outstanding mortgage balances. If your home appraised for $500,000 and your first mortgage balance is $300,000, you have $200,000 in equity. Lenders typically allow you to borrow 70–90% of that equity, so a loan of $140,000–$180,000 might be available. Lenders want to maintain a margin of safety; if you default, they will foreclose and sell the home. The equity cushion ensures they recover their principal even if the market softens. Conservative lending standards during downturns shrink this percentage, while competition in booms can push limits toward 90%.

Fixed rate vs. home equity line of credit

A home equity loan differs sharply from its sibling, a home equity line of credit (HELOC). An equity loan is a lump sum borrowed upfront with fixed payments. A HELOC is a revolving credit line, like a credit card but backed by your home, typically with a variable interest rate. Equity loans suit borrowers who need a specific amount for a defined purpose—funding a kitchen remodel, consolidating consumer debt, or a down payment on another property. HELOCs suit those who want flexible access to capital and are comfortable with interest rate risk. During rising rate environments, HELOC holders can face payment shocks; equity loan borrowers are insulated.

Tax deductibility of interest

Interest on home equity loans used to purchase or substantially improve the home—or to consolidate other home-related debt—may be deductible if you itemize deductions. (Interest on equity loans for other purposes is not deductible.) This can materially reduce the effective cost. A $150,000 loan at 7% costs $10,500 annually in interest; in a 24% tax bracket, the after-tax cost is $7,980. This tax advantage is unique to debt secured by a primary residence and represents a subsidy that can make an equity loan more attractive than unsecured borrowing for legitimate home purposes. However, the deduction phases out for high-income earners, and tax law has limited it to $750,000 of acquisition debt (including first and second mortgages combined).

Using equity loans for debt consolidation vs. other purposes

A common use is consolidating high-rate credit card debt. A $50,000 credit card balance at 18% costs $9,000 annually in interest; refinanced as equity loan debt at 7% with a 10-year term, the annual interest drops to $3,500. The catch: you have collateralized your home against what was previously unsecured debt. If you refinanced credit card spending into a mortgage because you over-borrowed, you have not addressed the underlying behavior. Many borrowers who consolidate then re-run credit cards and find themselves deeper in debt. The disciplinary value of equity loans is their tangibility: you cannot simply walk away from a home as you might default on a credit card.

The refinancing option when rates fall

If interest rates drop after you originate a home equity loan, you can refinance to a new loan at the lower rate. This carries closing costs (typically 2–5% of the loan amount), so the rate drop must be substantial enough to justify the expense. A drop from 8% to 7% on a $150,000 loan saves $1,500 a year in interest; if closing costs are $4,500, you break even in three years. For borrowers planning to stay in the home, this is sensible; for those unsure, it may not be. Some lenders offer rate-and-term refinancing with minimal costs, reducing the barrier to action.

Risk: the second mortgage position in foreclosure

Home equity loans are senior claims to unsecured creditors but junior to the first mortgage. If you default on both, the first mortgage holder forecloses and sells the home. Proceeds first satisfy the first mortgage; the equity loan gets what remains. If the home sells for less than both mortgages combined—an increasingly common scenario in downturns—the equity lender may suffer a loss and pursue a deficiency judgment against you. This risk structure incentivizes equity lenders to be selective about lending. It also means that home equity loans are not appropriate for frivolous borrowing; the collateral cost is your home.
