What are the critical mortgage underwriting principles for FRFIs?

Guideline B-20 underscores five key principles for robust residential mortgage underwriting, steering FRFIs toward judicious lending decisions and effective risk management.

Key Points

  • Lenders look at your whole financial picture when you apply for a mortgage.

  • Your ability to manage and pay off debt is the most important thing to lenders.

  • Lenders have a detailed set of rules they follow when deciding whether to give you a mortgage.

  • Lenders regularly review their mortgage rules to make sure they're still comfortable with the level of risk.
