A home equity line of credit, often called a HELOC, functions as a revolving credit source that lets homeowners borrow against the value they have built up in their property. The mechanics of the product mirror a credit card, with a lender setting a maximum limit based on the difference between the home’s current market value and the outstanding mortgage balance. This arrangement allows borrowers to access funds as needed, rather than taking out a lump sum all at once, making it a flexible option for covering significant expenses like education, medical bills, or repairs.
The loan operates through two distinct phases. During the initial draw period, which typically lasts ten years, the borrower can tap into the credit line and is usually only required to pay interest on the amount withdrawn. Once that window closes, the repayment period begins, at which point no further funds can be accessed. During this later stage, the entire borrowed balance must be paid back, often over a term that is twice as long as the draw period. This repayment phase is structured either as a lump-sum balloon payment minus the interest already paid or through a standard amortization schedule.
Because the property secures the debt, the maximum borrowing capacity is generally capped at 85% of the home’s equity. Borrowers do not need to use the full available credit, and no interest accrues on the portion of the line that remains untouched. This flexibility means a homeowner might only access a portion of the funds needed for a kitchen remodel or tuition, keeping monthly costs lower until the money is actually spent.

Most HELOCs come with variable interest rates that can shift from month to month, though they often start lower than rates for standard mortgages or personal loans. While the loans typically carry few closing costs, there may be upfront fees, annual charges, or penalties for early termination. Funds are usually withdrawn through online transfers, checks, or a linked credit card.
Historically, the tax-deductibility of the interest made these products appealing, particularly during the real estate boom of the early 2000s. However, after the 2008 financial crisis—which saw HELOCs contribute to the downturn when home values collapsed—the market tightened. In response to the high foreclosure rate that followed, regulations were introduced, and the Tax Cuts and Jobs Act of 2017 changed the rules. Until 2026, the interest on a HELOC is no longer tax-deductible unless the funds are used to buy, build, or substantially improve the home.
From a practical standpoint, this shift shifts the risk directly onto the homeowner. Unlike a standard loan where the bank eats the loss if the collateral loses value, a borrower who takes out a HELOC during a market downturn might find themselves owing more than the house is worth. This creates a difficult financial bind where selling the property won’t cover the debt, forcing the borrower to continue making payments even if the asset has depreciated significantly.
