Home Equity Loans and Lines of Credit: How Borrowing Against Your Property Works
Key Takeaways
- Home equity loans provide a fixed lump sum; HELOCs offer a revolving credit line you draw from as needed.
- Both products use your home as collateral, meaning non-payment could lead to foreclosure.
- Interest rates on equity products are generally lower than unsecured loans because of that collateral.
- HELOCs often carry variable interest rates, which means payments can rise if rates increase.
- Lenders typically cap borrowing at 80–85% of your home's appraised value minus what you owe.

Home Equity Borrowing
Home equity borrowing lets homeowners use the portion of their property they own outright — the difference between the home's market value and what they still owe on their mortgage — as collateral for a loan. Two main products exist: a home equity loan, which delivers a lump sum at a fixed rate, and a home equity line of credit (HELOC), which works like a revolving credit account. Both are forms of secured debt, meaning your home is pledged as security and can be at risk if you fail to repay.
Lenders typically require a combined loan-to-value (CLTV) ratio of 80–85% or lower, meaning your outstanding mortgage plus the new borrowing should not exceed 80–85% of the appraised home value.
What Home Equity Actually Means
Equity is the share of your home you truly own. If your property is appraised at $350,000 and your remaining mortgage balance is $210,000, your equity stands at $140,000. That figure represents real financial value — and lenders are willing to extend credit against it.
Equity grows in two ways: as you pay down your mortgage principal over time, and as property values appreciate. Either or both can increase how much a lender will let you borrow. Conversely, falling home values can shrink your equity, sometimes to the point where your property is worth less than you owe — a situation commonly called being "underwater."
Understanding how equity is calculated is the essential starting point. Because these are secured debt products, your home is not just background context — it is the primary protection the lender holds.
Home Equity Loans: The Lump-Sum Structure
A home equity loan — sometimes called a second mortgage — provides the borrower with a fixed amount of money upfront, repaid in equal monthly installments over a defined term, often five to thirty years. The interest rate is typically fixed for the life of the loan, making payments predictable.
This structure suits situations where the total cost is known in advance: a specific home renovation project, a large medical expense, or paying off high-interest debt in one transaction. Because the rate and payment are set from day one, budgeting is straightforward.

Maximum combined loan-to-value ratio most lenders allow
This is the standard industry threshold lenders use to determine how much equity borrowing they will extend relative to a home's appraised value.

ICE Mortgage Technology has reported that tappable home equity — the amount accessible while keeping an 80% LTV — reached record highs in recent years as property values appreciated.
The trade-off is inflexibility. Once the funds are disbursed, you cannot borrow more under the same agreement without taking out an additional loan. If your needs are ongoing or uncertain in size, this structure may be less practical than a line of credit.
HELOCs: A Flexible Revolving Credit Line
A home equity line of credit (HELOC) operates more like a credit card than a traditional loan. Lenders approve a maximum credit limit based on your available equity, and you draw funds as needed during a defined draw period — commonly five to ten years. You pay interest only on what you borrow, not the full limit.
After the draw period closes, a repayment period begins — typically ten to twenty years — during which you repay both principal and interest. Some HELOCs require a balloon payment at the end of the draw period, so reading the full terms carefully is essential. Our guide on key loan agreement clauses explains what to look for before signing.
Most HELOCs carry variable interest rates, often tied to the U.S. prime rate. This means your monthly payment can change when rates move. For a fuller understanding of how rate structures affect total repayment, see our explainer on fixed vs. variable rate loans.
Watch the Variable Rate Risk on HELOCs
Because most HELOCs are tied to a variable benchmark rate, a rising interest rate environment can meaningfully increase your monthly payments. Before opening a HELOC, model what your payment would look like if the rate increased by two or three percentage points. Some lenders offer rate caps or conversion options — ask about these before agreeing to terms.
How These Products Compare to Other Borrowing Options
Because home equity products are secured, their interest rates are typically lower than those on unsecured alternatives like personal loans or credit cards. That cost advantage can be meaningful over a long repayment term. However, an unsecured personal loan does not put your home at risk — a critical distinction for households evaluating their options. Our breakdown of personal loan structure and terms offers a useful comparison point.
The core trade-off is always the same: lower borrowing cost in exchange for pledging your most significant asset as collateral. That trade is worth examining carefully before proceeding.
