How does OSFI impact LTV and FRFI loan decisions?

OSFI (Office of the Superintendent of Financial Institutions) sets guidelines for Financial Institutions (FRFIs) concerning mortgage underwriting, especially LTV ratios.

Key Points

  • Lenders have limits on how much they can loan you based on the value of your home.

  • These limits can change, so lenders regularly review them.

  • If you refinance or your financial situation changes, your (/glossary/loan-to-value) ratio will be recalculated.

  • Lenders consider location and market trends to estimate your home's value when deciding on your loan.
