A home equity loan is a closed-end loan that provides a lump sum and uses the borrower’s home as collateral. It is sometimes called an equity loan or second mortgage. The borrower repays principal and interest under an agreed schedule, and failure to meet the loan terms can expose the home to foreclosure.
Home equity is the property’s estimated market value minus mortgage balances and other claims against it. Equity is not cash, and having equity does not guarantee loan approval or establish how much a lender will offer.
Key Takeaways
- A home equity loan normally advances one amount at closing rather than creating a revolving credit line.
- The loan may be junior to an existing first mortgage, but lien position depends on the title record and transaction structure.
- Available borrowing is commonly constrained by property value, existing liens, the lender’s combined loan-to-value policy, borrower capacity, and credit standards.
- A lower rate than unsecured credit does not make the transaction low risk: the borrower converts the home into collateral for the new obligation.
- Compare annual percentage rate, fees, term, payment schedule, lien terms, and total dollars paid rather than the monthly payment alone.
How a Home Equity Loan Works
A lender underwrites both the borrower and the property. The process can include:
- an application and income, debt, credit, and occupancy review;
- a property valuation or other acceptable value evidence;
- a title search for existing mortgages, tax liens, judgments, or other claims;
- calculation of the proposed combined loan-to-value ratio;
- disclosure and review of rate, APR, fees, term, payment, default, and lien provisions; and
- closing, funding, and recording or perfection of the lender’s security interest as required.
The resulting loan is separate from an existing first mortgage unless the transaction refinances or replaces that debt. A borrower with two loans must account for both payment schedules, maturity dates, and default provisions.
Home Equity and Borrowing Capacity
Basic home equity is:
$$
\text{Home Equity} = \text{Property Value} - \text{Existing Property Debt}
$$
That amount is not the same as available loan proceeds. A lender applying a maximum combined loan-to-value ratio may estimate capacity as:
$$
\text{Maximum New Loan} =
(\text{Property Value} \times \text{Maximum CLTV})
- \text{Existing Lien Balances}
$$
This is an underwriting illustration, not a universal limit or an offer. A lender may use a lower value, exclude part of the equity, account for amounts available under an existing line, or approve less based on income, credit, property type, lien position, or policy.
Worked Example
Assume a homeowner has:
| Input | Amount |
|---|
| Appraised property value | $500,000 |
| Existing first-mortgage balance | $250,000 |
| Illustrative maximum CLTV | 80% |
The homeowner’s gross equity is:
$$
\$500{,}000 - \$250{,}000 = \$250{,}000
$$
But the illustrative capacity under the CLTV constraint is:
$$
(\$500{,}000 \times 80\%) - \$250{,}000 = \$150{,}000
$$
The correct interpretation is not “the lender advances 80% of equity.” The lender in this example permits total mortgage debt equal to 80% of property value. Closing costs, another lien, or a lower approved amount could reduce net cash received.
If the new loan were $100,000, total property debt would be $350,000 and CLTV would be:
$$
\frac{\$250{,}000 + \$100{,}000}{\$500{,}000} = 70\%
$$
Home Equity Loan vs. HELOC and Cash-Out Refinance
| Feature | Home equity loan | HELOC | Cash-out refinance |
|---|
| Funding | One lump sum | Repeated draws up to a limit during the draw period | New larger mortgage replaces the existing mortgage |
| Credit structure | Closed-end installment loan | Open-end revolving line | Closed-end mortgage loan |
| Rate | Can be fixed or adjustable | Commonly adjustable; some plans permit fixed-rate conversions | Depends on the new mortgage product |
| Existing first mortgage | Usually remains in place | Usually remains in place | Repaid and replaced |
| Typical lien result | Often a second or junior lien | Often a second or junior lien | Commonly becomes the new first lien |
| Main comparison risk | Added payment and junior-lien costs | Variable payments, draw controls, and repayment-period change | Refinancing the entire existing balance and paying new closing costs |
The best comparison uses actual offers for the same amount and time horizon. A cash-out refinance can lower or raise the rate on the entire first-mortgage balance, while a home equity loan prices only the additional borrowing. A HELOC may provide flexibility but can introduce variable-rate and draw-period risk.
Interest Rate, APR, and Total Cost
The note rate determines interest under the contract, but it is not the full comparison. Review:
- annual percentage rate and how it was calculated;
- origination, application, appraisal, title, recording, and closing charges;
- whether fees are paid in cash or added to the balance;
- fixed or adjustable rate terms and any index, margin, cap, or floor;
- amortization term, maturity, and any balloon payment;
- late charges, default provisions, and prepayment terms; and
- optional products or services bundled with the loan.
A long term can reduce the scheduled payment while increasing the time debt remains outstanding. Using a mortgage secured by the home to repay shorter-term debt can also extend repayment and increase total interest even when the new rate is lower.
Lien Position and Foreclosure Risk
When an existing first mortgage remains, a home equity lender commonly takes a junior lien. Junior position means the claim generally receives collateral proceeds after senior claims and relevant costs, subject to applicable law and the governing documents.
The borrower still risks the home. A junior lender’s lower expected recovery does not remove its contractual remedies. Lien Priority should be verified through title records, loan documents, subordination agreements, and local law rather than inferred from the product name.
Risks and Limitations
- Property risk: A lower market value can reduce or eliminate the borrower’s remaining equity.
- Payment risk: The new loan adds a required payment alongside taxes, insurance, maintenance, and existing debt.
- Foreclosure risk: The home secures repayment and may be subject to enforcement after default.
- Lien risk: Existing tax, judgment, association, or mortgage claims can reduce collateral protection and borrowing capacity.
- Cost risk: Fees can make a relatively small or short-lived loan expensive.
- Rate risk: An adjustable-rate loan can produce higher interest and payments.
- Term-extension risk: Consolidating short-term debt into a longer mortgage can increase total borrowing cost.
- Behavior risk: Paying off revolving debt does not improve the balance sheet if the borrower runs those balances up again.
- Tax risk: Interest deductibility depends on current law and individual facts; secured-by-home status alone does not establish a deduction.
How to Evaluate an Offer
- Confirm the property’s supported value and every existing lien or credit-line limit.
- Calculate the proposed CLTV using the lender’s definitions.
- Reconcile gross loan amount, financed fees, payoffs, and net cash received.
- Compare rate, APR, payment, term, and total cost across equivalent loan amounts.
- Stress the payment for income interruption or an adjustable-rate increase where applicable.
- Read the note, mortgage or deed of trust, closing disclosures, and any appraisal or title documents.
- Understand default, foreclosure, prepayment, and maturity provisions before signing.

FAQs
Is a home equity loan the same as an equity loan?
In consumer mortgage usage, equity loan often means home equity loan. Because the shorter phrase can be ambiguous, verify that the loan is secured by a home, whether it is closed-end, and which lien position it will occupy.
Is a home equity loan always a second mortgage?
No. It is commonly a second mortgage when an existing first mortgage remains, but it could be the only or senior lien in another transaction. The recorded documents and applicable law establish lien position.
Does available home equity equal the amount a borrower can receive?
No. A lender can limit total property debt to a percentage of supported value and approve less based on repayment capacity, credit, property, lien, or policy factors. Fees and required payoffs can also reduce net proceeds.
