When are guarantors/co-signors important and what is required?

Guarantors and co-signors can substantially fortify a mortgage application, especially when the borrower has a limited credit history or is self-employed.

FRFIs, however, are obligated to conduct a rigorous credit assessment of the guarantor/co-signor. This is a partnership where everyone's financial health matters.

Key Points

  • Lenders will carefully check the credit of anyone who guarantees your mortgage.

  • The more the lender relies on your guarantor, the more thorough the credit check will be.

  • Your guarantor needs to fully understand the legal responsibilities they're taking on.

  • Having a guarantor might help your mortgage qualify as a standard residential loan in some cases.

  • Typically, acceptable guarantors are banks, financial institutions, or insurance companies.
