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 only pay interest on the amount you use. 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. HELOCs suit ongoing projects or emergencies; home equity loans suit one-time large expenses where you want payment certainty.
Most lenders allow you to borrow up to 80–90% of your home's value, minus what you still owe on your mortgage. For example: a $400,000 home with an 85% LTV limit and a $200,000 mortgage balance gives you a maximum HELOC of $140,000. Use our Borrowing Power Calculator to get your exact figure.
Almost all HELOCs have variable interest rates tied to the prime rate (which moves with Federal Reserve decisions). 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 is only tax-deductible if the funds are used to buy, build, or substantially improve the home that secures the loan. Interest on a HELOC used for debt consolidation, a holiday, or general expenses is not deductible. Always consult a tax professional for advice specific to your situation.
