What You Need To Know About Co-Signing A Mortgage

Team Gill • November 21, 2023

So you’re thinking about co-signing on a mortgage? Great, let’s talk about what that looks like. Although it’s nice to be in a position to help someone qualify for a mortgage, it’s not a decision that you should make lightly. Co-signing a mortgage could have a significant impact on your financial future. Here are some things to consider.


You’re fully responsible for the mortgage.


Regardless if you’re the principal borrower, co-borrower, or co-signor, if your name is on the mortgage, you are 100% responsible for the debt of the mortgage. Although the term co-signor makes it sound like you’re somehow removed from the actual mortgage, you have all the same legal obligations as everyone else on the mortgage. When you co-sign for a mortgage, you guarantee that the mortgage payments will be made, even if you aren’t the one making them.


So, if the primary applicant cannot make the payments for whatever reason, you’ll be expected to make them on their behalf. If payments aren’t made, and the mortgage goes into default, the lender will take legal action. This could negatively impact your credit score. So it’s an excellent idea to make sure you trust the primary applicant or have a way to monitor that payments are, in fact, being made so that you don’t end up in a bad financial situation.

 

You’re on the mortgage until they can qualify to remove you.


Once the initial mortgage term has been completed, you won’t be automatically removed from the mortgage. The primary applicant will have to make a new application in their own name and qualify for the mortgage on their own merit. If they don’t qualify, you’ll be kept on the mortgage for the next term.


So before co-signing, it’s a good idea to discuss how long you can expect your name will be on the mortgage. Having a clear and open conversation with the primary applicant and your independent mortgage professional will help outline expectations.


Co-signing a mortgage impacts your debt service ratio.


When you co-sign for a mortgage, all of the debt of the co-signed mortgage is counted in your debt service ratios. This means that if you’re looking to qualify for another mortgage in the future, you’ll have to include the payments of the co-signed mortgage in those calculations, even though you aren’t the one making the payments directly.


As this could significantly impact the amount you could borrow in the future, before you co-sign a mortgage, you’ll want to assess your financial future and decide if co-signing makes sense.


Co-signing a mortgage means helping someone get ahead.


While there are certainly things to consider when agreeing to co-sign on a mortgage application, chances are, by being a co-signor, you'll be helping someone you care for get ahead in life. The key to co-signing well is to outline expectations and over-communicate through the mortgage process.


If you have any questions about co-signing on a mortgage or about the mortgage application process in general, please connect anytime. It would be a pleasure to work with you.

Everything You Need to Know About Mortgage Financing in Canada

By Team Gill • September 22, 2026
For most Canadians, buying a home isn’t possible without a mortgage. And while getting a mortgage may seem straightforward—borrow money, buy a home, pay it back—it’s the details that make the difference. Understanding how mortgages work (and what to watch out for) is key to keeping your borrowing costs as low as possible. The Basics: How a Mortgage Works A mortgage is a loan secured against your property. You agree to pay it back over an amortization period (often 25 years), divided into shorter terms (ranging from 6 months to 10 years). Each term comes with its own interest rate and rules. While the interest rate is important, it’s not the only thing that determines the true cost of your mortgage. Features, penalties, and flexibility all play a role—and sometimes a slightly higher rate can save you thousands in the long run. Key Questions to Ask Before Choosing a Mortgage How long will you stay in the property? Your timeframe helps determine the right term length and product. Do you need flexibility to move? If a work transfer or lifestyle change is possible, portability may be important. What are the penalties for breaking the mortgage early? This is one of the biggest factors in the real cost of borrowing. A low rate won’t save you if breaking costs you tens of thousands. How are penalties calculated? Some lenders use more borrower-friendly formulas than others. It’s not easy to calculate yourself—get professional help. Can you make extra payments? Prepayment privileges allow you to pay off your mortgage faster, potentially saving years of interest. How is the mortgage registered on title? Some registrations (like collateral charges) can limit your ability to switch lenders at renewal without extra costs. Which type of mortgage fits best? Fixed, variable, HELOCs, or even reverse mortgages each have their place depending on your financial and life situation. What’s your down payment? A larger down payment could reduce or eliminate mortgage insurance premiums, saving thousands upfront. Why the Lowest Rate Isn’t Always the Best Choice It’s tempting to chase the lowest rate, but mortgages with rock-bottom pricing often come with restrictive terms. For example, saving 0.10% on your rate may put a few extra dollars in your pocket each month, but if the mortgage has harsh penalties, you could end up paying thousands more if you break it early. The goal isn’t just the lowest rate—it’s the lowest overall cost of borrowing . That’s why it’s so important to look beyond the headline number and consider the whole picture. The Bottom Line Mortgage financing in Canada is about more than rate shopping. It’s about aligning your mortgage with your financial goals, lifestyle, and future plans. The best way to do that is to work with an independent mortgage professional who can walk you through the fine print and help you secure the product that truly keeps your costs low. If you’d like to explore your options—or review your current mortgage to see if it’s really working in your favour—let’s connect. I’d be happy to help.

What Is a Cashback Mortgage and How Does It Work?

By Team Gill • September 8, 2026
Cashback Mortgages: Are They Worth It? Here’s What You Need to Know If you’ve been exploring mortgage options and come across the term cashback mortgage , you might be wondering what exactly it means—and whether it’s a smart move. Let’s break it down in simple terms. What Is a Cashback Mortgage? A cashback mortgage is just like a regular mortgage—but with one extra feature: you receive a lump sum of cash when the mortgage closes . This cash is typically: A fixed amount , or A percentage of the total mortgage , usually between 1% and 7% , depending on your mortgage term and lender. The money is tax-free and paid directly to you on closing day. What Can You Use the Cashback For? There are no restrictions on how you use the funds. Here are some common uses: Covering closing costs Buying new furniture Renovations or home upgrades Paying off high-interest debt Boosting your cashflow during a tight transition Whether it’s to help you settle in or catch up financially, cashback can offer a helpful buffer— but it comes at a cost . The True Cost of a Cashback Mortgage Here’s the part many people overlook: cashback mortgages come with higher interest rates than standard mortgages. Why? Because the lender is essentially advancing you a small loan upfront—and they’re going to make that money back (and then some) through your mortgage payments. So while the upfront cash feels like a bonus, you’ll pay more in interest over time to have that convenience. Breaking Down the Numbers It’s hard to give a blanket answer about how much more you’ll pay since it depends on: Your interest rate The cashback amount The mortgage term Your payment schedule This is why it’s important to run the numbers with a mortgage professional who can help you compare this option with others based on your personal financial situation. Are You Eligible for a Cashback Mortgage? Not everyone qualifies. Cashback mortgages generally come with stricter requirements . Lenders often want to see: Excellent credit history Strong, stable income Low debt-to-income ratio If your mortgage file includes anything “outside the box”—like being self-employed or recently changing jobs—qualifying for a cashback mortgage might be tough. What If You Need to Break the Mortgage? This is one of the biggest risks with cashback mortgages. If your circumstances change and you need to break your mortgage early, you could be on the hook for: Paying back some or all of the cashback you received, and A prepayment penalty (typically the interest rate differential or 3 months’ interest—whichever is higher) That can be a very expensive combination. So if there’s even a chance you might need to sell, refinance, or move before your term is up, a cashback mortgage might not be the best fit. Should You Consider a Cashback Mortgage? Maybe—but only with eyes wide open. Cashback mortgages can be helpful in the right scenario, but they’re not free money. They’re a lending tool that benefits the lender , and the key is knowing exactly what you’re agreeing to. Final Thoughts: Talk to an Expert First Choosing the right mortgage isn’t just about the lowest rate or the biggest perk—it’s about making a choice that fits your whole financial picture.
