Understanding Your HELOC Borrowing Power
A Home Equity Line of Credit (HELOC) functions like a revolving credit card, but it is secured by your home. Unlike a traditional home equity loan that provides a lump sum, a HELOC allows you to withdraw funds as needed, pay them back, and withdraw them again during the "draw period."
How the Calculation Works
Lenders typically use the Combined Loan-to-Value (CLTV) ratio to determine how much you can borrow. The standard calculation follows this logic:
- Determine the Cap: Multiply your home's appraised value by the lender's CLTV limit (usually 80% to 85%).
- Subtract Existing Debt: Deduct your current mortgage balance and any other liens on the property.
- The Remainder: The remaining amount is your potential credit limit.
Real-World Example
Imagine your home is worth $450,000 and you owe $300,000 on your primary mortgage. If a lender offers an 80% CLTV limit:
- 1. $450,000 x 0.80 = $360,000 (Maximum allowable total debt)
- 2. $360,000 – $300,000 = $60,000 (Available HELOC limit)
Factors That Influence Your Approval
While equity is the primary factor, lenders will also evaluate:
- Credit Score: A score of 720+ usually secures the best interest rates.
- Debt-to-Income (DTI) Ratio: Lenders prefer a DTI below 43%.
- Appraisal: A professional appraisal will be required to verify the actual market value of your home.
- Income Stability: Proof of consistent income via W2s or tax returns.
Pro Tip: HELOC interest rates are usually variable, meaning your monthly payments could increase if market interest rates rise. Always factor in a "buffer" for potential rate hikes when planning your budget.
