Why This Matters for Your Refinance (The LTV Factor)

  • Loan-to-Value (LTV) is the ratio of your loan to the home's value.
  • The Appraisal Gap: In Illinois, older homes vary wildly in condition. This affects your LTV heavily.
  • The Strategy: Before refinancing, ensure your home shows well. Small cosmetic fixes can ensure your appraisal comes in high enough to keep your LTV below 80%, helping you avoid PMI.
