Lenders cap total borrowing (mortgage + HELOC) at a percentage of your home's value — the combined loan-to-value (CLTV) ratio. Most allow 80–85%; some credit unions go to 90%. Actual approval also depends on credit score, income, and debt-to-income ratio. Your home secures the line: missed payments risk foreclosure.
