A Guide to Assumable Mortgages

by | March 7, 2026

An assumable mortgage is a financing option that allows an outstanding mortgage to be transferred from the current owner to a buyer. While assumable mortgages are not very common in Canada, most fixed-rate mortgages can be assumed, while variable-rate and home equity lines of credit cannot. It’s important to weigh the pros and cons before deciding if an assumable mortgage is the right fit for you.

Key Takeaways:

  • An assumable mortgage allows the transfer of an existing mortgage from the seller to the buyer.
  • Fixed-rate mortgages are usually assumable, while variable-rate mortgages and home equity lines of credit are not.
  • Consider the advantages and disadvantages of assumable mortgages before making a decision.
  • Assumable mortgages can provide benefits for both sellers and buyers.
  • Discuss with a mortgage broker to understand the requirements and options available to you.

Pros of Assumable Mortgages

If you’re the seller and willing to have someone assume your mortgage, you may reap the benefits of assumable mortgages. Not only can you potentially secure a better price for your home, but you’ll also have access to a wider pool of potential buyers. This increased demand can be a significant advantage when it comes to selling your property.

Another advantage of assumable mortgages is that they can help you avoid prepayment fees. If you’re considering downsizing before your mortgage term ends, an assumable mortgage allows you to transfer the loan to the buyer. By doing so, you can save on costly prepayment penalties that would otherwise apply if you paid off your mortgage early.

On the other hand, if you’re the buyer and current interest rates are higher than the rate on the existing mortgage, assuming the loan could be highly beneficial. By taking over the mortgage, you can lock in a lower interest rate, potentially saving you thousands of dollars over the life of the loan.

Buyers also stand to benefit from fewer costs associated with assumable mortgages compared to obtaining a new mortgage. Assuming a mortgage means you won’t need to secure new financing or pay for expensive out-of-pocket expenses, especially if the equity in the home is low.

Cons of Assumable Mortgages

While assumable mortgages offer certain advantages, it’s essential to consider the potential drawbacks before deciding whether this financing option is right for you. Here are the cons of assumable mortgages that you should be aware of:

1. Higher Down Payment Requirements

If you’re the buyer and the seller has a significant amount of equity in the home, you may need to make a large down payment or secure a second mortgage for the balance not covered by the existing mortgage. This can pose challenges if the two lenders don’t cooperate or increase the risk of default.

2. Potential Liability for Sellers

Sellers should be cautious when opting for an assumable mortgage as they may remain responsible for repaying the lender if the new borrower defaults on the loan. This potential liability can create financial risks for sellers even after transferring the mortgage to a new buyer.

3. Risk of Home Value Depreciation

Additionally, if the condition of the home deteriorates over time and its resale value is affected, the original borrower may be held liable for the difference. This means that even after transferring the mortgage, sellers can still be financially responsible for any decrease in the home’s value.

4. Release Request Requirement

To release the seller from any ongoing obligations, it’s crucial to have a release request approved by the lender. Failing to obtain this approval may result in the seller continuing to be responsible for the mortgage, even if ownership has been transferred.

5. Banks May or May Not Do Assumables

Banks don’t like Assumable Mortgages. Considering that about 60% of Canadians get the mortgages from a bank, the option of Assuming a mortgage is not possible if the person selling the home doesn’t have a mortgage attached to it that can be assumed.

However, Scotiabank presently does allow assumable mortgages. The process is handled at the branch level. Clients can contact their servicing branch or the 1-800 Scotia service line for more information.

In comparison, TD does not allow assumable mortgages.

CIBC does allow assumable mortgages under certain conditions on some of their products. There may be administrative fees involved in processing the assumption.

However, alternate lenders, many credit unions, and monoline lenders are more likely to allow their mortgage products to be Assumed.

Overall, assumable mortgages come with some potential downsides that everyone involved should carefully consider. Sellers must be aware of their ongoing financial obligations and potential liabilities, while buyers need to assess the feasibility of making larger down payments or securing second mortgages. By fully understanding the cons of assumable mortgages, you can make an informed decision about whether this financing option is the right fit for your specific circumstances.

The Assumable Mortgage Process

Assuming a mortgage involves taking over the existing mortgage’s principal balance, interest rate, repayment period, and other contractual terms. This process provides an opportunity for buyers to acquire a home loan without the need for obtaining a new mortgage. If you are considering assuming a mortgage, here is a step-by-step guide to help you navigate the process.

Evaluating the Mortgage

Before assuming a mortgage, it’s essential to review the terms and conditions of the existing loan. You should carefully assess factors such as the interest rate, repayment schedule, and any additional costs associated with the mortgage. It’s crucial to understand the obligations and responsibilities involved to make an informed decision.

Contact the Lender

Once you have assessed the mortgage and are interested in assuming it, the next step is to contact the lender. Reach out to their customer service or mortgage department and express your intention to assume the loan. They will provide you with the necessary information and guide you through the required steps.

Qualification and Application

To assume a mortgage, you need to qualify with the lender. This typically involves meeting their criteria, such as credit score, debt-to-income ratio, and sufficient assets. The lender will assess your financial situation to ensure you can handle the mortgage payments. Prepare the required documents, such as proof of income, bank statements, and identification, and submit an application for the assumable loan.

Lender Approval

Before the assumption can proceed, the lender of the original mortgage must approve the transfer. The lender will review your application, evaluate your financial standing, and assess your ability to repay the loan. This step ensures that both the buyer and seller are protected during the mortgage assumption process.

Down Payment and Closing

If the agreed price of the home exceeds the remaining mortgage balance, you may need to provide a down payment to cover the difference. This is necessary to ensure that the outstanding loan is fully repaid. Once the down payment is made, the closing process can commence, which involves signing the necessary legal documents and transferring the ownership of the property.

Porting Your Mortgage

In addition to assumable mortgages, another option to consider when transferring your mortgage is porting. Porting allows you to move your current mortgage, along with its rate and terms, from one property to another. This can be highly beneficial if your current mortgage rate is lower than the prevailing rates in the market.

However, it’s important to note that not all mortgages are portable. Some lenders may impose time restrictions or have specific criteria that must be met for a mortgage to be eligible for porting. Therefore, it is crucial to discuss your options with a mortgage broker before starting the house-hunting process. They can provide you with valuable insights and guidance on whether porting your mortgage is the right choice for your specific situation.

Advantages of Porting Your Mortgage

Porting your mortgage can offer several advantages:

  1. Consistency: By porting your mortgage, you can maintain the same interest rate and other favourable terms of your existing mortgage. This allows you to avoid potentially higher interest rates prevalent in the current market.
  2. Savings: If your current mortgage rate is lower than the prevailing rates, porting can save you money over the long term. This is especially beneficial if you have a substantial mortgage balance.
  3. Flexibility: Porting provides you with the flexibility to move to a new property without incurring penalties or breaking your existing mortgage contract. This can be particularly useful if you need to relocate due to work or personal reasons.

By taking advantage of porting, you can continue to benefit from your existing mortgage terms and potentially save money on interest payments. However, it’s important to carefully review the terms and conditions of your mortgage agreement with your lender to ensure that porting is a viable option for your specific mortgage.

Overall, porting your mortgage can be a strategic financial move that allows you to transfer your better mortgage terms to a new property. It’s crucial to consult with a mortgage professional who can provide personalized advice based on your unique circumstances and help you make an informed decision.

The Impact of Assumable Mortgages on Real Estate Transactions

Assumable mortgages play a significant role in shaping real estate transactions. Their impact is particularly notable in attracting more buyers to the market, especially when the interest rates on existing mortgages are lower compared to the current rates. This dynamic leads to increased housing demand, allowing supply to meet the pent-up demand.

While assumable mortgages are less common in Canada compared to the United States, where approximately 20% of mortgages are assumable, most Canadian mortgages are portable. This means that homeowners can enjoy the benefit of lower interest rates on their existing mortgages when purchasing a new property.

“Assumable mortgages offer a unique advantage in real estate transactions. They can make a substantial difference in the number of potential buyers and the market’s overall liquidity.”

By giving buyers the option to assume an existing mortgage, real estate transactions become more accessible and attractive to individuals who may find it challenging to secure new financing or pay hefty out-of-pocket expenses. The lower costs associated with assuming a mortgage can be particularly beneficial when the equity in the property is low.

The impact of assumable mortgages on real estate transactions is further highlighted by the flexibility they offer to sellers. By allowing potential buyers to assume their mortgage, sellers have a broader pool of buyers to choose from, potentially resulting in a higher sale price for their property.

In conclusion, assumable mortgages have a positive impact on real estate transactions by attracting more buyers and increasing market liquidity. With the potential for lower interest rates and reduced costs, assumable mortgages serve as a valuable financing option for those looking to enter the real estate market.

Conclusion

Assumable mortgages provide a specialized financing option that can benefit both buyers and sellers in the Canadian real estate market. With assumable mortgages, sellers can attract a wider range of potential buyers and avoid prepayment fees. On the other hand, buyers can take advantage of lower interest rates and save on closing costs.

Before deciding on an assumable mortgage, it’s crucial for both parties to thoroughly discuss the risks and benefits associated with this type of financing. Additionally, it is important to ensure that they meet the specific requirements set by the lender. While assumable mortgages may not be widespread in Canada, they remain a viable option worth considering in certain scenarios where it can offer unique advantages over non-assumable mortgages.

Overall, assumable mortgages present an opportunity for buyers and sellers to navigate the real estate market more flexibly and potentially save money. While it’s important to carefully evaluate the terms and conditions of these mortgages, the potential benefits they offer make them an option to explore for those involved in real estate transactions in Canada.
