For many Canadians, owning a home is a significant milestone, often seen as a symbol of financial stability and personal success. However, with the rising costs of real estate in major cities and even rural areas, achieving homeownership on one’s own can feel increasingly out of reach. For those who find themselves priced out of the market, one solution is gaining traction: co-mortgages. But what exactly is a co-mortgage, and how can it help people buy homes together? This post will explore the concept of a co-mortgage, its benefits, the process involved, and considerations for anyone thinking about entering into such an agreement.
1. What is a Co-Mortgage?

A co-mortgage, also known as joint ownership, occurs when two or more people come together to purchase a property. Instead of one person being responsible for the mortgage, multiple parties share the mortgage, equity, and ownership of the home. These co-buyers could be friends, family members, business partners, or even strangers who have been introduced through co-buying platforms, such as Co Buy Canada. Each party contributes to the down payment, monthly mortgage payments, property taxes, and other expenses related to the home.
Co-mortgages can be a powerful tool for individuals who might not otherwise qualify for a mortgage on their own or for those who want to share the financial responsibility of owning a home. This method of co-ownership allows people to pool their financial resources and achieve homeownership in a more affordable and sustainable way.
2. The Legal Structure of a Co-Mortgage

In a co-mortgage agreement, all parties involved are co-owners of the property. In Canada, there are generally two types of co-ownership structures:
- Joint Tenancy: In this arrangement, all co-owners have an equal share of the property. If one owner passes away, their share of the property automatically transfers to the surviving co-owner(s). This structure is most common among married couples or close family members.
- Tenants in Common: This structure allows for unequal shares of the property to be assigned. For instance, one co-buyer could own 60% of the home while the other owns 40%. In the event of an owner’s death, their share does not automatically transfer to the other co-owner(s) but can be passed on to a designated beneficiary in their will. Tenants in common arrangements are popular for non-relatives or friends purchasing property together, as they allow for more flexibility in ownership stakes.
When entering a co-mortgage, it’s crucial to have a legal agreement in place that outlines each party’s responsibilities, ownership shares, and what happens in the case of a sale, death, or other significant life events. A co-ownership agreement is typically drawn up by a real estate lawyer to protect all parties involved.
3. The Benefits of a Co-Mortgage
There are several key benefits to co-buying a property through a co-mortgage, especially for those who are unable to buy a home on their own.
a) Increased Buying Power
One of the most significant advantages of a co-mortgage is the ability to pool resources, which can increase buying power. Instead of qualifying for a smaller mortgage individually, co-buyers can combine their income and assets to secure a larger mortgage, which allows them to purchase a more desirable property in a better location.
b) Shared Financial Responsibility
A co-mortgage allows for shared financial responsibility. Co-buyers split the costs of the down payment, mortgage payments, property taxes, insurance, and maintenance. This arrangement can make homeownership more affordable and accessible, particularly in markets where real estate prices are high. It can also reduce the financial burden on individuals who may struggle to maintain a home on their own.
c) Access to Homeownership Sooner
For many Canadians, saving for a down payment can take years, particularly in urban markets like Vancouver, Toronto, or Montreal. A co-mortgage enables people to enter the housing market sooner by allowing them to split the cost of the down payment and other upfront expenses. This can be especially beneficial for first-time homebuyers or those who may not have access to large sums of savings.
d) Building Equity Faster
By entering the housing market sooner through a co-mortgage, co-owners can start building equity faster. As the property appreciates in value over time, each co-owner benefits from the appreciation, allowing them to build wealth more quickly than if they had waited to buy a property on their own.
e) Flexibility in Ownership
As mentioned earlier, the tenants in common structure allows for flexibility in ownership shares. This flexibility can be beneficial for co-buyers who may want to contribute different amounts to the down payment or monthly expenses. It also allows for the possibility of adding or removing co-owners over time, depending on the needs and circumstances of the parties involved.
4. The Process of Securing a Co-Mortgage

Securing a co-mortgage involves several key steps, each of which requires careful planning and communication between the co-buyers. Here’s a brief overview of the process:
a) Assessing Financial Readiness
Before entering into a co-mortgage, each co-buyer should assess their financial readiness. This includes checking their credit score, determining how much they can contribute to the down payment, and estimating monthly mortgage payments. It’s also essential to have open and honest discussions about financial goals, as all parties will be legally responsible for the mortgage.
b) Securing Pre-Approval
Once the co-buyers have assessed their financial readiness, the next step is to seek mortgage pre-approval. This process involves submitting financial documents to a lender to determine how much the co-buyers can borrow collectively. Since multiple people are applying, the lender will evaluate each person’s credit history, income, and debt levels to assess the overall risk.
c) Choosing a Property
With pre-approval in hand, co-buyers can begin searching for a property that meets their needs and budget. It’s essential to consider each person’s priorities and preferences when selecting a home, as co-ownership requires collaboration and compromise.
d) Finalizing the Co-Mortgage Agreement
Before finalizing the purchase, the co-buyers should work with a real estate lawyer to create a co-ownership agreement. This agreement should outline the financial contributions of each party, how the property will be maintained, and how any disputes will be resolved. It’s also important to address what happens in the event that one co-buyer wants to sell their share or if there is a major life event, such as a marriage, divorce, or death.
e) Closing the Deal
Once the co-ownership agreement is in place, the co-buyers can proceed with the closing process. This involves signing the necessary legal documents, transferring funds, and taking possession of the property. From that point forward, each co-buyer is responsible for their share of the mortgage payments and property upkeep.
5. Considerations and Risks
While a co-mortgage can offer many benefits, it also comes with potential risks. It’s essential to consider these risks before entering into such an arrangement:
- Shared Financial Responsibility: If one co-buyer defaults on their mortgage payments, the other party(ies) will be responsible for covering the shortfall. This could lead to financial strain or damage to credit scores if not handled properly.
- Differing Priorities: Co-buyers may have different goals or timelines for selling the property, which could create tension down the road. It’s essential to have a clear exit strategy in place from the beginning.
- Potential Legal Complications: If disputes arise between co-buyers, resolving them may require legal intervention, which can be costly and time-consuming.
Conclusion

A co-mortgage offers a viable solution for Canadians looking to enter the housing market by pooling resources and sharing financial responsibility. While there are challenges and risks involved, careful planning, clear communication, and a well-drafted co-ownership agreement can help co-buyers navigate the process successfully. If you’re considering co-buying a home in Canada, platforms like Co Buy Canada provide valuable tools and resources to help you every step of the way.
