When it comes to obtaining a mortgage, some individuals may find it challenging to meet the lender’s requirements on their own. In such cases, having a co-signer can be beneficial. A co-signer is an individual who agrees to take on the responsibility of the mortgage alongside the primary borrower. This article will explore who can co-sign a mortgage and the implications of doing so.

Who can co-sign a mortgage?

Family members: One common option for a co-signer is a family member. This could include parents, siblings, or even grandparents. Lenders often prefer family members as co-signers because they are more likely to have a vested interest in the borrower’s success.

Spouse or domestic partner: If you are married or in a domestic partnership, your spouse or partner can co-sign the mortgage. This is a common arrangement, as both parties are typically invested in the property and its success.

Friends: In some cases, close friends may be willing to co-sign a mortgage. However, it is important to carefully consider this option, as financial arrangements with friends can sometimes strain relationships.

Employers or colleagues: In unique circumstances, an employer or colleague may be willing to co-sign a mortgage. This is more common in situations where the employer has a vested interest in the borrower’s success, such as when the borrower is relocating for work.

Other individuals: While less common, there may be other individuals who are willing to co-sign a mortgage. This could include mentors, business partners, or even charitable organizations.

Implications of co-signing a mortgage

Shared responsibility: When someone co-signs a mortgage, they are equally responsible for the debt. This means that if the primary borrower defaults on the loan, the co-signer is legally obligated to repay it. It is crucial for both parties to understand the implications and potential risks involved.

Impact on credit: Co-signing a mortgage can have an impact on the credit of both the primary borrower and the co-signer. If the primary borrower makes late payments or defaults on the loan, it will negatively affect both credit scores. On the other hand, if the primary borrower makes timely payments, it can positively impact both credit scores.

Difficulty obtaining future credit: Co-signing a mortgage may impact the co-signer’s ability to obtain credit in the future. Lenders will consider the co-signed mortgage as a liability when assessing the co-signer’s creditworthiness for future loans.

Potential strain on relationships: Co-signing a mortgage can put a strain on relationships, especially if there are financial difficulties or disagreements regarding the property. It is essential to have open and honest communication and establish clear expectations before entering into a co-signing arrangement.


In summary, a variety of individuals can co-sign a mortgage, including family members, spouses or domestic partners, friends, employers or colleagues, and other individuals. Co-signing a mortgage comes with shared responsibility, potential credit implications, and the possibility of strain on relationships. It is crucial for both the primary borrower and the co-signer to carefully consider the implications and potential risks before entering into such an arrangement.
