What is a Guarantor?
A guarantor is someone who agrees to be legally responsible for a mortgage or loan if the primary borrower fails to meet repayment obligations.
Why Guarantors Matter in Real Estate
In Canadian real estate, guarantors help strengthen a mortgage application without necessarily being added to the property's title. Unlike a co-signer, a guarantor usually acts as a financial backup rather than a joint applicant.
Key points include:- Guarantors are liable for the loan in case of default
- Their income and credit are considered in underwriting
- They are not typically owners of the property
Lenders may require a guarantor when the borrower has limited income, thin credit history, or is self-employed. Legal advice is recommended due to the financial risk involved.
Understanding the role of a guarantor helps families and applicants navigate lending support and legal exposure in high-stakes transactions.
Example of a Guarantor in Action
A parent acts as a guarantor for their child’s mortgage, improving approval odds without being added to the home’s title.
Key Takeaways
