Porting Your Mortgage

Tracy Head • August 9, 2024

Most lenders say that their mortgages are portable.


What does this mean?


The simplest way to explain porting is this – if you sell your current home, rather than charging a penalty to pay out your current mortgage, your lender transfers the terms and conditions (and balance) of your mortgage to your next home.


Key here is knowing that porting isn’t always an option. Its also important to note that porting isn’t always the best option.

Its important to do the math to see if porting makes sense.


Porting policies differ from lender to lender and product to product.


As an example, my favorite lender will only port a variable mortgage on the same day (ie: the current mortgage is paid out and the replacement mortgage finalizes the same day) and dollar-for-dollar. This means you take the exact same amount of money and are not able to increase the size of the mortgage if you need more money.


Another of my go-to lenders will allow a port of a variable rate mortgage and use their blend and extend policies so you can increase the amount of funds if needed.


Many lenders offer a blend and extend option when porting their mortgages. This means that should you need additional money for your purchase those funds are added to your current mortgage and the lender comes up with a new blended rate based on a calculation of original mortgage funds sitting at the rate you initially signed at and the new funds needed sitting at current interest rates. 


One of the chartered banks moves the exact same mortgage to the new property and adds a second mortgage for any additional funds required.


I like to do the math for clients to see if porting is the best route, or if it makes more sense to pay a penalty to take completely new rates.


As an example, I’m working with a young couple right now that renewed into a new five year term in May at 5.14 per cent. After two years of searching their dream home came on the market. They are needing almost three times the amount of mortgage as compared to their current mortgage.


In this case, as we are working with the same lender they are being charged three months’ interest penalty instead of an interest rate differential penalty which would be approximately four times higher.


They are electing to pay the penalty (calculated at $2600) and take a completely new mortgage at 4.59%.

I looked at the interest savings and in this case the clients are saving over $9,000 over the next five years by paying the $2600 penalty.


Staying with the current lender and porting the current mortgage is almost always what I recommend to my clients. I do the math and most times it makes sense to port.


Sometimes, however, it does make sense to pay a penalty and start fresh.


If you are selling and buying mid-way through your mortgage term I encourage you to connect with your mortgage person to see what makes the most sense for you financially. You may be a bit surprised as to where the numbers land.

If there is one question I hear more than any other from Canadians looking to buy a home, it's this: "How much can I actually afford?" It's a great question, and frankly, it's one that deserves more attention than simply finding out the maximum mortgage amount a lender is willing to approve. While mortgage qualification guidelines provide a useful starting point, they don't always tell the whole story. The amount a lender says you can borrow and the amount you can comfortably afford are often two very different numbers. Let's start with what affects affordability. One of the biggest factors is the type and amount of income you earn. A salaried employee with a stable employment history will generally have a straightforward qualification process. However, self-employed individuals, commissioned salespeople, seasonal workers, and those with multiple income sources may qualify differently. Lenders carefully examine the stability and consistency of income when determining how much mortgage financing they are willing to provide. Consumer debt is another major factor. Credit card balances, lines of credit, car loans, personal loans, and other monthly obligations all reduce purchasing power. Every dollar committed to debt payments is a dollar that cannot be allocated toward a mortgage payment. It is not uncommon for borrowers to increase their purchasing power significantly simply by reducing or eliminating high monthly debt obligations before applying for a mortgage. The size of your down payment also plays an important role. A larger down payment reduces the amount you need to borrow and often improves your overall financial position. In some cases, a larger down payment can help borrowers qualify for homes that might otherwise be out of reach. It can also lower monthly payments and reduce the total amount of interest paid over the life of the mortgage. Of course, lenders use formulas and qualification ratios to determine affordability. These calculations consider mortgage payments, property taxes, heating costs, and other obligations. However, these formulas do not always account for the realities of everyday life. That's why I often encourage clients to think beyond what they can qualify for and focus on what they can comfortably live with. A mortgage should support your life, not control it. Many Canadians are surprised to discover that once they factor in groceries, fuel, insurance, utilities, childcare, activities for children, pet expenses, travel plans, and rising day-to-day living costs, there is less room in the monthly budget than they initially expected. Homeownership also comes with unexpected expenses. Furnaces fail. Appliances break down. Roofs need repairs. Vehicles require maintenance. Life happens. If your mortgage payment consumes every available dollar each month, even a relatively small unexpected expense can create financial stress. For this reason, I often recommend that homebuyers leave some breathing room in their budget whenever possible. Choosing a home that costs slightly less than the maximum amount you qualify for can provide flexibility and peace of mind. It allows you to continue saving for retirement, build an emergency fund, take a family vacation, or simply sleep better at night knowing you have a financial cushion. Before making an offer on a home, I encourage buyers to look at the complete monthly picture. Consider not only the mortgage payment but also property taxes, home insurance, utilities, maintenance costs, and any strata or condominium fees. Then compare those costs against your current spending habits and financial goals. The goal is not simply to buy a home. The goal is to own a home comfortably while maintaining the lifestyle and financial security that matter to you and your family. The most successful homeowners are often not the ones who borrow the most money. They're the ones who make thoughtful decisions, leave room in their budget for life's surprises, and build long-term financial stability along the way. So the next time you ask, "How much can I actually afford?" remember that the answer isn't just about what the bank will approve. It's about what allows you to enjoy your home while still enjoying your life.
