Home equity loan basics

A home equity loan, often called a second mortgage, pays a lump sum with a fixed rate and fixed payment. It sits behind your first mortgage, so lenders limit the combined loan-to-value (first mortgage + new loan ÷ home value), commonly to 80%–85%.

Worked example

Home worth $400,000, mortgage $200,000, 85% CLTV limit: maximum = $400,000 × 0.85 − $200,000 = $140,000. Borrowing $75,000 brings the combined balance to $275,000, or 68.75% CLTV. At 8.25% for 15 years: $727.61 a month.

Home equity loan or HELOC?

Choose a loan for a single known cost (a roof, a payoff) and a fixed payment. Choose a HELOC for costs spread over time, where you pay interest only on what you draw. Either way the home is collateral.

Example rates are for comparison only, not offers or current quotes. Your rate depends on credit, loan-to-value and lender.
