What is a HELOC?

A Home Equity Line of Credit (HELOC) lets you borrow against your home's equity. It works like a credit card with a variable interest rate and a credit limit based on your equity. HELOCs provide flexible access to funds when you need them.

Calculating Available Equity

Available Equity = (Home Value x Max LTV) - Current Mortgage Balance. Most lenders allow 75-85% LTV. Example: $400,000 home value, $250,000 mortgage, 80% max LTV. Available = ($400,000 x 0.80) - $250,000 = $320,000 - $250,000 = $70,000.

HELOC vs Home Equity Loan

HELOC: Variable rate, Revolving credit (borrow as needed), Interest-only option during draw period, Flexible access. Home Equity Loan: Fixed rate, Lump sum disbursement, Fixed monthly payments, Predictable costs. Choose HELOC for flexibility; Home Equity Loan for one-time needs.

Best Uses for HELOC

Good: Home improvements (may be tax-deductible), Debt consolidation at lower rate, Emergency fund backup, Education expenses. Risky: Vacations, Luxury purchases, Investment speculation. Remember: Your home is collateral. Defaulting can result in foreclosure.
