HELOC Complete Guide 2026: How to Use a Home Equity Line of Credit

A Home Equity Line of Credit gives you access to your home's equity as a revolving credit facility — draw what you need, repay it, and draw again within the draw period. For homeowners who want flexible access to equity without the commitment of a full cash-out refinance, a HELOC is a powerful tool.

How a HELOC Works

A HELOC has two phases. The draw period — typically 10 years — allows you to borrow up to your credit limit, repay, and borrow again. Payments during this period are typically interest-only on the outstanding balance.

The repayment period — typically 20 years following the draw period — requires principal and interest repayment on whatever balance remains. Your payment increases substantially when the repayment period begins.

How Much Can You Borrow

Most lenders allow a combined loan-to-value — your first mortgage plus the HELOC — of up to 80 to 90% of your home's appraised value. If your home is worth $500,000 and you owe $300,000, an 80% CLTV allows a HELOC of up to $100,000. Some lenders go to 90% CLTV for well-qualified borrowers.

Rate Structure

HELOCs carry variable rates tied to Prime Rate plus a margin. As Prime Rate changes — driven by Fed actions — your HELOC rate and interest payment changes accordingly. Some lenders offer fixed-rate conversion options for some or all of the outstanding balance.

Best Uses for a HELOC

Home renovation projects where you want to draw funds in phases. A ready reserve for real estate investment down payments. Short-term bridge financing situations. Education costs or significant variable expenses over a multi-year period.

When a HELOC Is Not the Right Tool

If you need a large lump sum, want rate certainty, or are not comfortable with variable rate risk, a cash-out refinance to a fixed rate may serve you better.
