Use this calculator to estimate your potential First Lien Home Equity Line of Credit (HELOC) and initial monthly payments. A First Lien HELOC replaces your primary mortgage, allowing you to access home equity while consolidating your first mortgage into a flexible line of credit.
Understanding First Lien HELOCs
A First Lien Home Equity Line of Credit (HELOC) is a unique financial product that allows you to replace your existing primary mortgage with a flexible line of credit. Unlike a traditional second mortgage HELOC, a first lien HELOC becomes the primary lien on your home, often offering a way to consolidate debt, access significant equity, and potentially lower your overall monthly payments by utilizing interest-only payments during the draw period.
How it Works
With a first lien HELOC, the lender determines a maximum credit line based on your home's appraised value and their Loan-to-Value (LTV) limits. This credit line is then used to pay off your existing first mortgage, and any remaining available credit can be drawn upon as needed. You only pay interest on the amount you've actually drawn, not the entire credit line. Payments during the draw period are often interest-only, providing flexibility, but principal repayment typically begins during the subsequent repayment period.
Key Benefits
Flexibility: Access funds as needed, up to your credit limit, and only pay interest on what you borrow.
Potential for Lower Payments: Interest-only payments during the draw period can significantly reduce your monthly outlay compared to a traditional mortgage.
Consolidation: Can be used to pay off an existing first mortgage and other high-interest debts.
Access to Equity: Unlock a substantial portion of your home's equity for various needs like home improvements, education, or other large expenses.
Considerations
Variable Interest Rate: Most HELOCs have variable rates, meaning your monthly payments can fluctuate with market changes (e.g., Prime Rate).
Draw and Repayment Periods: Understand the terms of both periods. The draw period allows you to borrow, while the repayment period requires principal and interest payments.
Risk of Foreclosure: As it's secured by your home, failure to make payments can lead to foreclosure.
Closing Costs: Like traditional mortgages, first lien HELOCs can come with closing costs, though some lenders may offer promotions.
Always consult with a financial advisor and compare offers from multiple lenders to ensure a first lien HELOC is the right financial solution for your specific situation.
