How do lenders assess the creditworthiness of co-signers and guarantors?

Lenders thoroughly evaluate the financial stability of co-signers and guarantors to mitigate mortgage default risks.

FRFIs prioritize verifiable income sources to prevent fraud and ensure long-term financial stability. For example:

Key Points

  • Lenders will want solid proof of your co-signer or guarantor's income, like tax returns.

  • Lenders look for steady income, considering what might happen if income stops.

  • If your co-signer or guarantor is self-employed, they'll need to provide tax documents and business records.

  • It can be tricky to use income earned outside of Canada, so lenders will be extra careful.

  • Mortgage insurance can help lower the risk for the lender.
