Understanding Home Equity Loans
A home equity loan, often referred to as a "second mortgage," allows you to borrow against the difference between your home's current market value and your remaining mortgage balance. Unlike a HELOC (Home Equity Line of Credit), a home equity loan provides a lump sum of cash with a fixed interest rate and a set repayment schedule.
How the Home Equity Calculation Works
Lenders use a metric called the Combined Loan-to-Value (CLTV) ratio to determine how much you can borrow. Most traditional banks limit your CLTV to 80%, though some credit unions may allow up to 90% for borrowers with excellent credit.
The basic formula is:
(Current Home Value × Max LTV Percentage) – Current Mortgage Balance = Your Borrowable Equity
Example Calculation
Imagine your home is worth $500,000 and you still owe $300,000 on your first mortgage. If a lender allows an 80% CLTV:
$500,000 × 0.80 = $400,000 (Maximum total debt allowed)
$400,000 – $300,000 = $100,000 (Max Home Equity Loan amount)
Common Uses for Home Equity Loans
Since home equity loans offer fixed rates and potential tax deductibility (if used for home improvements), they are popular for:
Home Renovations: Increasing the value of your property.
Debt Consolidation: Paying off high-interest credit card debt with a lower-interest loan.
Major Expenses: Funding education, medical bills, or significant life events.
Key Requirements for Approval
To qualify for a home equity loan, lenders typically look for three main factors:
Equity: Usually at least 15% to 20% equity in the home.
Credit Score: A score of 620 or higher, with better rates for scores above 740.
DTI Ratio: A Debt-to-Income ratio below 43% is generally preferred.
