Buying a new home is an exciting and rewarding experience, but it can also come with a lot of financial decisions and responsibilities. One of the most important considerations when purchasing a new property is what to do with your existing mortgage. If you have found your dream home but still have a remaining mortgage on your current property, you may be wondering how to make the transition as smooth and cost-effective as possible. 

This is where porting a mortgage comes into play. In simple terms, porting mortgage means transferring your existing mortgage from one property to another. While it may seem like a straightforward process, there are certain factors to consider and steps to take to ensure a successful porting experience. In this blog post, we will guide you through the process of porting mortgage and provide tips to help you navigate it successfully.

Understanding the Basics of Mortgage Porting

Mortgage port is a unique feature offered by some lenders that allows borrowers to transfer their existing mortgage from their current property to a new one. This option essentially gives homeowners the convenience of maintaining their original mortgage terms such as the interest rate and repayment schedule. The key benefit of mortgage porting lies in its potential to save you a considerable amount of money.

This could be in terms of evading early repayment charges or avoiding higher interest rates that could come with obtaining a new mortgage. It’s important to understand that while a transfer mortgage can be beneficial, it is a process that requires a thorough understanding of your current mortgage terms and clear communication with your lender.

Benefits of Porting Your Mortgage

Porting mortgage presents several advantages that can make this option particularly appealing to homeowners. 

Cost savings: 

One of the primary benefits of this is the potential for significant cost savings. By using a mortgage porting calculator, you can gain insights into the potential financial benefits. For instance, porting can allow you to maintain your current interest rate, which can be particularly beneficial if the current market rates are higher. You may also avoid certain fees, such as prepayment penalties or the costs associated with applying for a new mortgage

Continuity of terms: 

Mortgage relocation allows you to carry over the terms of your existing mortgage to your new property. This continuity can provide a level of comfort and predictability, particularly when it comes to budgeting for your mortgage payments. 


Mortgage relocation provides a degree of flexibility that may not be available with other mortgage options. This feature can be especially advantageous if you’re buying and selling properties simultaneously. The process enables you to align the closing dates of both transactions, potentially reducing stress and logistical challenges. 

Potential for additional borrowing: 

Depending on your lender’s policies and your financial situation, this might provide an opportunity to borrow additional funds, which can be useful if the purchase price of your new home exceeds the mortgage balance on your current property.

Drawbacks of Porting Your Mortgage

Despite its advantages, porting a mortgage can present certain drawbacks that homeowners need to consider. 

Limited options: 

When you opt for a transfer mortgage, you’re limited to your existing lender. This may restrain you from exploring potentially better mortgage deals from other lenders. It’s crucial to consider how to port mortgage from one lender to another, to ensure the most cost-effective choice. 

Extra costs: 

Although a mortgage porting calculator may reveal potential savings, there could be unexpected expenses. This may include property valuation fees, transfer costs, or higher borrowing rates if additional funds are needed. These costs can add up and negatively impact the financial benefits of porting. 

Stringent conditions: 

The porting process requires meeting certain conditions. This can include a strict timing synchronization between the sale and purchase of properties, and passing another affordability test, which may not be favorable for all homeowners. 

Limited flexibility: 

Depending on your existing mortgage terms, porting may limit your flexibility to change or renegotiate these terms in relation to your new property or changing financial circumstances. It’s imperative to weigh these potential drawbacks against the benefits before deciding on porting mortgage.

Mortgage porting involves a series of strategic steps that can help ensure a smooth and successful transition. Here’s a comprehensive guide on how to port a mortgage

Assess your current mortgage terms: 

Begin by closely examining your existing mortgage terms. Understand whether it comes with a portability feature and identify the conditions attached to it. This initial assessment can help determine if porting your mortgage is a viable option. 

Communicate with your lender: 

Having open and regular communication with your lender is crucial. Discuss your plans to port and gain a clear understanding of the process, requirements, and any potential charges involved. 

Conduct a cost comparison: 

Utilize a mortgage porting calculator to compare the costs of porting your existing mortgage versus obtaining a new one. This comparison can help you identify the more cost-effective option.

Align the property transactions: 

For successful porting, the sale of your existing property and the purchase of your new one must be synchronized. Coordination with all parties involved, including your real estate agent and your lender, is necessary for this alignment. 

Apply for porting: 

Once you’ve weighed your options and decided to port, submit your application to the lender. You’ll need to provide all required documentation and undergo another affordability assessment. 

Review the ported mortgage terms: 

After approval, review the ported mortgage terms before finalization. Ensure they align with your financial circumstances and long-term goals. 

Considerations Before Deciding to Port

Before deciding to undertake the process of transferring a mortgage, it’s crucial to analyze several key factors. First, ensure you fully understand how to port a mortgage. Having a detailed grasp of the process can inform your decision and set realistic expectations. Second, evaluate your current financial status and future projections. The decision to port should align with your long-term financial goals and current capacity to manage the mortgage. 

Your credit score: 

Lenders re-evaluate your creditworthiness during the porting process. A significant decrease in your credit score since your initial mortgage approval may impact your porting eligibility and terms. 


The timing alignment between the sale of your current property and the purchase of the new one is critical when porting mortgage. Assess the feasibility of managing this synchronization. 

Market conditions: 

Current market conditions can significantly influence the benefits of porting. For instance, if interest rates have plummeted since your original mortgage, acquiring a new mortgage might be more beneficial. 

Property value: 

If your new property is significantly more expensive, you may need to borrow additional funds at a potentially higher interest rate. 

What to Expect During the Process

Embarking on the mortgage port journey can seem daunting, but having a clear understanding of what to expect can make the process much smoother. Here’s a rundown of what typically unfolds: 

Initial consultation with your lender: 

The process starts with a meeting with your existing lender to discuss your plans to port your mortgage. They will guide you through the requirements, timelines, and costs involved. This is also a good time to ask any questions and clarify any doubts you may have about the process. 

Completing the application: 

After the initial consultation, you’ll need to fill out an application to request a mortgage port. Your lender will provide this form, which will likely require you to provide updated financial information and details about your new property. 

Undergoing a new affordability assessment: 

As part of the porting process, your lender will reassess your financial situation to ensure that you can afford the mortgage on your new property. This will likely involve providing recent pay stubs, bank statements, and potentially undergoing a credit check. 

Coordinating the sale and purchase transactions: 

One of the most crucial aspects of the porting process is aligning the sale of your current property and the purchase of the new one. This may require close coordination with your real estate agent, your lender, and potentially the buyers and sellers. 

Finalizing the ported mortgage: 

Once everything has been approved, you’ll move towards finalizing the ported mortgage. Your lender will provide a new mortgage agreement that reflects the terms of your ported mortgage, which you’ll need to review and sign before it becomes official.

Concluding Thoughts

Porting a mortgage can be a strategic move when buying a new home, offering significant benefits including cost savings and continuity of terms. However, it’s not without its challenges, and the success of this process depends on numerous factors including your financial stability, market conditions, and the specifics of your current mortgage. Before deciding to embark on this journey, consider seeking advice from a mortgage broker or consult with your lender to gain a full understanding of the process and its implications.
