When applying for a loan, rental agreement, or other financial obligations, you may be asked to provide a guarantor. But what exactly is a guarantor, and how does their role affect both borrowers and lenders?

The role of a guarantor is often pivotal in securing loans, particularly for those who may face difficulties obtaining credit due to a low credit score or insufficient income.
According to a 2020 report by the Federal Reserve, approximately 15% of American adults have a subprime credit score, which is typically below 620. This segment of the population often struggles to obtain loans without additional security measures, such as a guarantor.
In fact, 40% of rental agreements require a guarantor, especially for first-time renters or students. A guarantor is an individual who agrees to pay the debt if the primary borrower defaults. The presence of a guarantor can significantly increase a borrower’s chance of loan approval.
Studies show that borrowers with a guarantor are 40% more likely to secure financing compared to those without one, as it reduces the lender’s risk. However, the role of a guarantor involves substantial responsibility, and understanding the implications is essential for both parties involved.
What is a guarantor?
A guarantor is a person who agrees to repay a borrower’s debt if the borrower fails to meet their financial obligations. Guarantors provide an extra layer of security for lenders by pledging their own assets or income as collateral.
In some cases, individuals may act as their own guarantors if they have sufficient assets to secure a loan. The term “guarantor” is sometimes used interchangeably with “surety.”
Key takeaways
- A guarantor promises to repay a borrower’s debt if the borrower defaults.
- Guarantors pledge their assets or income as collateral.
- They can also help verify an individual’s identity for jobs or passports.
- Unlike a co-signer, a guarantor has no ownership rights over the borrowed asset.
- If the borrower defaults, the guarantor becomes legally responsible for repayment.
How does a guarantor work?
Guarantors are typically:
- Over 18 years old
- Residents of the country where the loan is issued
- Financially stable, with a strong credit history and sufficient income
If the borrower misses payments or defaults, the lender can legally pursue the guarantor for repayment. In some cases, late payments may also result in additional fees or interest charges for the guarantor.

Types of Guarantors

There are several types of guarantors, each with distinct roles and responsibilities. These roles can vary based on the nature of the agreement, the type of loan, or the asset involved.
1. Personal Guarantor
A personal guarantor is an individual, typically a family member, friend, or a close associate of the borrower, who agrees to take responsibility for the debt if the borrower fails to make the required payments. This type of guarantor is most common in personal loans, student loans, or small business financing, particularly when the borrower lacks sufficient creditworthiness or has limited income.
- Student Loans: A parent or guardian may act as a guarantor for a student taking out a loan for education expenses.
- Rental Agreements: Parents often act as personal guarantors for young tenants or students who do not have a stable income or credit history.
2. Corporate Guarantor
A corporate guarantor is a company or business entity that guarantees the loan or debt of another business or individual. This type of guarantee is particularly common in business loans, especially when a smaller company needs financing but lacks sufficient assets or creditworthiness to secure a loan on its own. The parent company of a subsidiary or a corporation may act as the corporate guarantor for the debt of a smaller entity or individual within the same organisation.
- Business Loans: A parent company may act as a guarantor for the loan taken out by a subsidiary that lacks sufficient financial history or resources.
- Commercial Leases: A large corporation may guarantee the lease of a smaller company that is leasing space for the first time.
3. Government Guarantor
A government guarantor involves a government entity or agency that guarantees a loan or debt, typically to encourage economic activity or promote social objectives, such as affordable housing or education. This type of guarantee is often seen in public sector financing or loans intended for individuals or businesses in certain sectors, such as small businesses, students, or first-time homebuyers.
- Federal Housing Administration (FHA) Loans: In the United States, the government may act as a guarantor for home loans made to first-time buyers, particularly those who are unable to meet the traditional credit criteria.
- Student Loan Guarantees: Government-backed student loans where the government guarantees repayment in the event the borrower defaults.
4. Collateral Guarantor
A collateral guarantor is an individual or entity that pledges assets or property to secure a loan. In this case, the guarantor does not necessarily promise to repay the loan themselves but offers their property as collateral to the lender in case the borrower defaults. The collateral may include personal assets such as real estate, vehicles, or other valuable items.
- Secured Loans: A borrower may have a collateral guarantor who provides their own property as security against the loan. If the borrower defaults, the lender may seize the collateral to recover the owed amount.
- Business Financing: A business owner may ask for a collateral guarantor to pledge company assets as security against a loan for business expansion.
When Do You Need a Guarantor?
There are several situations where you might need a guarantor. Here are some common scenarios:
1. When the borrower has poor credit
If a borrower has a poor credit history or has previously defaulted on loans, a lender may require a guarantor to provide additional security. A guarantor can reassure the lender that the loan will be repaid, even if the borrower cannot meet their obligations.
2. For first-time renters
It’s common for first-time renters, such as students, to need a guarantor when signing a lease. This is particularly the case for younger tenants who may not have a strong credit history or a reliable income. Parents or guardians often act as guarantors in these situations, taking responsibility if the tenant fails to pay the rent.
3. For large loans
In the case of larger loans, such as mortgages or business loans, a lender may request a guarantor to reduce their risk. Guarantors in these cases provide extra security for the lender, making it easier for the borrower to qualify for significant amounts of financing.
4. When the borrower has insufficient income
Even with a solid credit history, a borrower may not qualify for a loan if their income doesn’t meet the lender’s criteria. In these cases, a guarantor with sufficient income can help make up for the borrower’s financial shortcomings.
Advantages of having a guarantor
Having a guarantor can provide several benefits, particularly for the borrower:
- Increased loan approval chances: Lenders are more likely to approve loans for borrowers with a guarantor, even if the borrower’s credit history is less than stellar.
- Better loan terms: With the added security of a guarantor, the borrower may be able to access a loan with lower interest rates or higher loan amounts.
- Improved credit history: Borrowers with poor credit may see an improvement in their credit scores if the loan is repaid on time, as long as the guarantor is backing the loan.
Disadvantages of being a guarantor
However, there are several disadvantages associated with being a guarantor:
- Financial liability: If the borrower defaults, the guarantor must repay the debt, which could place a significant financial burden on them.
- Credit score impact: The guarantor’s credit score could suffer if the borrower fails to make timely payments, potentially limiting the guarantor’s ability to obtain credit in the future.
- Limited borrowing power: By agreeing to guarantee a loan, the guarantor may reduce their ability to take out new loans, as the loan they are backing may count against their overall borrowing capacity.
Final thoughts
A guarantor plays a crucial role in many financial agreements by providing lenders with an added layer of security. Whether it’s for a personal loan, business financing, or a rental agreement, having a guarantor can make a significant difference in securing the loan or property. However, becoming a guarantor is not without risks.
Guarantors should carefully assess the financial and personal implications of their commitment before agreeing to take on this responsibility. Understanding the different types of guarantors, the roles they play, and the potential consequences of default is essential for anyone considering becoming a guarantor or requiring one for a loan.
