Porting Your Mortgage

Jeff Johnson • September 18, 2024

Porting your mortgage is when you transfer the remainder of your current mortgage term, outstanding principal balance, and interest rate to a new property if you’re selling your existing home and buying a new one.


Now, despite what some big banks would lead you to believe, porting your mortgage is not an easy process. It’s not a magic process that guarantees you will qualify to purchase a new property using the mortgage you had on a previous property.


In addition to re-qualifying for the mortgage you already have, the lender will also assess the property you’re looking to purchase. Many moving parts come into play. You’re more likely to have significant setbacks throughout the process than you are to execute a flawless port. Here are some of the reasons:


You may not qualify for the mortgage


Let’s say you’re moving to a new city to take a new job. If you’re relying on porting your mortgage to buy a new property, you’ll have to substantiate your new income. If you’re on probation or changed professions, there’s a chance the lender will decline your application. Porting a mortgage is a lot like qualifying for a new mortgage, just with more conditions.


The property you are buying has to be approved


So let’s say that your income isn’t an issue and that you qualify for the mortgage. The subject property you want to purchase has to be approved as well. Just because the lender accepted your last property as collateral for the mortgage doesn’t mean the lender will accept the new property. The lender will require an appraisal and scrutinize the condition of the property you’re looking to buy.


Property values are rarely the same


Chances are, if you’re selling a property and buying a new one, there’ll be some price difference. When looking to port a mortgage, if the new property’s value is higher than your previous property, requiring a higher mortgage amount, you’ll most likely have to take a blended rate on the new money, which could increase your payment. If the property value is considerably less, you might incur a penalty to reduce the total mortgage amount.


You still need a downpayment


Porting a mortgage isn’t just a simple case of swapping one property for another while keeping the same mortgage. You’re still required to come up with a downpayment on the new property.


You’ll most likely have to pay a penalty


Most lenders will charge the total discharge penalty when you sell your property and take it from the sale proceeds. The penalty is then refunded when you execute the port and purchase the new property. So if you are relying on the proceeds of sale to come up with your downpayment, you might have to make other arrangements.


Timelines rarely work out


When assessing the housing market, It’s usually a buyer’s market or a seller’s market, not both at the same time. So although you may be able to sell your property overnight, you might not be able to find a suitable property to buy. Alternatively, you may be able to find many suitable properties to purchase while your house sits on the market with no showings.


And, chances are, when you end up selling your property and find a new property to buy, the closing dates rarely match up perfectly.


Different lenders have different port periods


Understanding that different lenders have different port periods is where the fine print in the mortgage documents comes into play. Did you know that depending on the lender, the time you have to port your mortgage can range from one day to six months? So if it’s one day, your lawyer will have to close both the sale of your property and the purchase of your new property on the same day, or the port won’t work.


Or, with a more extended port period, you run the risk of selling your house with the intention of porting the mortgage, only to not be able to find a suitable property to buy.


So while the idea of porting your mortgage can seem like a good idea, and it might even make sense if you have a low rate that you want to carry over to a property of similar value, it’s always a good idea to get professional mortgage advice and look at all your options.


While porting your mortgage is a nice feature to have because it provides you with options, please understand that it is not a guarantee that you’ll be able to swap out properties and keep making the same payments. There’s a lot to know.


If you’re looking to sell your existing property and buy a new one, please connect anytime. It would be a pleasure to walk you through the process and help you consider all your options, including a port if that makes the most sense!

How to Legally Assign a Construction Mortgage

By Jeff Johnson • July 8, 2026
Why More Mortgage Options Matter—Especially for Assignment Purchases One of the biggest advantages of working with an independent mortgage professional is access to choice. Instead of being limited to one lender and one set of products, mortgage brokers work with multiple lenders—each with different guidelines, risk tolerances, and mortgage solutions. That flexibility becomes especially valuable when your situation doesn’t fit neatly into a “standard” box. A great example of this is purchasing new construction through an assignment contract . Why Assignment Purchases Can Be Challenging Assignment purchases are often viewed as higher risk by traditional lenders. Rather than declining these deals outright, many lenders quietly make them difficult by adding layers of conditions, restrictions, or uncertainty. This can lead to delays, frustration, or financing falling apart late in the process. The Good News There are lenders—available exclusively through the broker channel —that have clear, favourable policies for assignment purchases. With the right lender and proper planning, these transactions are absolutely doable. Typical Financing Requirements for Assignment Purchases While every situation is unique, many lenders that allow assignment financing look for the following: Standard purchase qualification, including income verification, credit, and down payment Assignments accepted at either the original purchase price or current market value Minimum 620 credit score , with no prior bankruptcies or consumer proposals The full down payment must come from the purchaser —seller incentives cannot be used Required Documentation To secure financing, lenders typically require: The original purchase agreement signed by all parties The MLS listing (if applicable) The assignment agreement signed by the builder, original purchaser, and new buyer Any side agreements outlining changes to the purchase price A full appraisal to confirm value This list isn’t exhaustive, but it highlights that while assignment purchases require more coordination, they are very achievable with the right lender and guidance. Final Thoughts Assignment contracts can open doors to great opportunities—but only if your financing supports the transaction. This is where access to multiple lenders and specialized policies makes a real difference. If you’re considering purchasing new construction through an assignment, or if you’d like to explore more traditional purchase options, feel free to connect anytime. I’d be happy to walk you through the mortgage products available and help you choose an option that doesn’t limit your financing possibilities.

Co-Signing a Mortgage in Canada: Pros, Cons & What to Expect

Co-Signing a Mortgage in Canada: Pros, Cons & What to Expect Thinking about co-signing a mortgage? On the surface, it might seem like a simple way to help someone you care about achieve homeownership. But before you sign on the dotted line, it’s important to understand exactly what co-signing means—for them and for you. You’re Fully Responsible When you co-sign, your name is on the mortgage—and that makes you just as responsible as the primary borrower. If payments are missed, the lender won’t only go after them; they’ll come after you too. Missed payments or default can damage your credit score and put your financial health at risk. That’s why trust is key. If you’re going to co-sign, make sure you have a clear picture of the borrower’s ability to manage payments—and consider monitoring the account to protect yourself. You’re Committed Until They Can Stand Alone Co-signing isn’t temporary by default. Even once the initial mortgage term ends, you won’t automatically be removed. The borrower has to re-qualify on their own, and only then can your name be taken off. If they don’t qualify, you stay on the mortgage for another term. Before agreeing, talk openly about expectations: How long might you be on the mortgage? What’s the plan for eventually removing you? Having these conversations upfront prevents surprises later. It Affects Your Own Borrowing Power When lenders calculate your debt service ratios, the co-signed mortgage counts as your debt—even if you never make a payment on it. This could reduce how much you’re able to borrow in the future, whether it’s for your own home, an investment property, or even refinancing. If you see another mortgage in your future, you’ll want to consider how co-signing could limit your options. The Upside: Helping Someone Get Ahead On the positive side, co-signing can be life-changing for the borrower. You could be helping a family member or friend buy their first home, start building equity, or take an important step forward financially. If handled with clear expectations and trust, it can be a meaningful way to support someone you care about. The Bottom Line Co-signing a mortgage comes with both risks and rewards. It’s not a decision to take lightly, but with careful planning, transparency, and professional advice, it can be done responsibly. If you’re considering co-signing—or want to explore safer alternatives—let’s connect. I’d be happy to walk you through what to expect and help you decide if it’s the right move for you.
