Why This Matters for Your Refinance (The LTV Factor)

  • Loan-to-Value (LTV) is the ratio of your loan to your home's worth.
  • The Watch-Out: With values dipping slightly (-0.7%), your LTV might have ticked up.
  • The Strategy: If you bought recently with a small down payment (e.g., 3%), be careful. You want to ensure you don't owe more than 80% of the home's value if you want the best refinance rates. If you are close to that line, pay down a little extra principal before applying.
