Common Questions

HELOC Basics — Answered

A Home Equity Line of Credit (HELOC) lets you borrow against the equity in your home, up to a set credit limit. It works like a credit card — you draw what you need, when you need it, and interest is generally calculated on your outstanding balance rather than the entire credit limit. Draw-period payments, fees, and terms vary by lender. HELOCs typically have a draw period (usually 10 years) followed by a repayment period (usually 20 years).
A home equity loan gives you a fixed lump sum upfront at a fixed interest rate — predictable payments, like a second mortgage. A HELOC is a flexible credit line with a variable rate — you draw as needed. A HELOC may offer flexibility for expenses over time, while a home equity loan may offer more predictable payments. Both involve borrowing secured by your home.
Lenders set their own combined loan-to-value limits, and the amount available depends on your existing secured debt and other underwriting requirements. For example, with a $400,000 home, an assumed 85% combined loan-to-value limit, and $200,000 of existing secured debt, the illustrative remaining capacity is $140,000 before lender-specific conditions and costs. Use our Borrowing Power Calculator to explore an estimate based on your assumptions, not a lender offer.
Many HELOCs have variable interest rates, often linked to a benchmark such as the prime rate. This means your monthly payment can rise or fall over time. Some lenders offer a fixed-rate lock on a portion of your balance — ask your lender about this option if payment predictability matters to you.
HELOC interest may be deductible as home mortgage interest when borrowed funds are used to buy, build, or substantially improve the home securing the loan, subject to IRS rules, applicable debt limits, and itemizing deductions. Interest on HELOC funds used for personal expenses, such as credit card debt consolidation or vacations, generally is not deductible as home mortgage interest. See IRS Publication 936 for details, and consult a qualified tax professional about your circumstances.
