What is the Loan-to-Value (LTV) ratio, and how does it impact my ability to refinance?

The (/glossary/loan-to-value) (LTV) ratio plays a critical role in the refinancing process.

Key Points

  • Your (/glossary/loan-to-value) (LTV) shows how much of your home's value you're borrowing, and it affects your interest rate.

  • Lenders set limits on how high your LTV can be for different mortgages, and they keep a close eye on these limits.

  • Lenders will look at things that might affect your home's value when figuring out your LTV for a refinance.

  • Your LTV is recalculated whenever you refinance your mortgage.

Generally, a lower LTV (indicating more equity) translates to more favorable refinancing terms. OSFI mandates that FRFIs maintain dynamic LTV ratio frameworks. The LTV is recalculated whenever you refinance and at any other time it's deemed prudent, considering shifts in a borrower's risk profile or delinquency status, using a suitable valuation or appraisal method.

If you have a Home Equity Line of Credit (HELOC), the maximum combined LTV (including mortgage and HELOC) is typically up to 80% of your home's value.
