How Home Equity Borrowing Works
Borrowing against equity converts part of your ownership stake into secured debt. The payment, risk, and available amount depend on value, existing debt, rate, and lender rules.

How available equity is screened
Lenders consider property value, the first-mortgage balance, combined loan-to-value, income, credit, and the requested line or loan. An online result is not a credit decision.
Price the full obligation
Include rate changes, origination or annual fees, appraisal, closing costs, and the possibility that the property value falls. Compare a fixed second mortgage with a HELOC before using the funds to consolidate debt.
Keep the collateral risk visible
The debt is secured by your home. Use the calculators as planning tools and review the lender’s disclosures and repayment terms carefully.
