Understanding Home Equity Loans

A home equity loan, often referred to as a "second mortgage," allows homeowners to borrow against the value of their property. The loan is secured by the equity you have built up in your home—the difference between the current market value of your home and the remaining balance on your mortgage.

How to Calculate Your Borrowing Power

Lenders typically use a Loan-to-Value (LTV) ratio to determine how much they are willing to lend. Most lenders limit your total combined debt (primary mortgage + home equity loan) to 80% or 85% of your home's appraised value.

Example Calculation:
If your home is worth $400,000 and your lender allows an 85% LTV, your total borrowing limit is $340,000. If you currently owe $250,000 on your mortgage, you could potentially borrow up to $90,000 in home equity ($340,000 – $250,000).

Key Benefits of Home Equity Loans

  • Fixed Interest Rates: Unlike HELOCs, standard home equity loans usually offer fixed rates and predictable monthly payments.
  • Lump Sum Funding: Receive all the cash at once, making it ideal for large expenses like home renovations or debt consolidation.
  • Potential Tax Deductions: If the funds are used to "buy, build, or substantially improve" the home that secures the loan, the interest may be tax-deductible (consult a tax advisor).

Important Considerations

Because your home serves as collateral, failure to make payments can lead to foreclosure. It is crucial to use a Home Equity Loan Calculator to ensure the new monthly payment fits comfortably within your budget alongside your existing financial obligations.

Factors That Affect Your Rate

While our calculator uses a standard interest rate input, your actual rate will be determined by:

  1. Credit Score: Higher scores typically unlock lower interest rates.
  2. LTV Ratio: Borrowing a smaller percentage of your home's value reduces the lender's risk.
  3. Debt-to-Income (DTI) Ratio: Lenders look at your monthly income versus your total monthly debt payments.
