Before You Co-Sign a Mortgage

Adrian Markiewicz • November 20, 2024

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.

Bank of Canada Rate Announcement Dec 10th, 2025

By Adrian Markiewicz • December 10, 2025
Bank of Canada maintains policy rate at 2.1/4%. FOR IMMEDIATE RELEASE Media Relations Ottawa, Ontario December 10, 2025 The Bank of Canada today held its target for the overnight rate at 2.25%, with the Bank Rate at 2.5% and the deposit rate at 2.20%. Major economies around the world continue to show resilience to US trade protectionism, but uncertainty is still high. In the United States, economic growth is being supported by strong consumption and a surge in AI investment. The US government shutdown caused volatility in quarterly growth and delayed the release of some key economic data. Tariffs are causing some upward pressure on US inflation. In the euro area, economic growth has been stronger than expected, with the services sector showing particular resilience. In China, soft domestic demand, including more weakness in the housing market, is weighing on growth. Global financial conditions, oil prices, and the Canadian dollar are all roughly unchanged since the Bank’s October Monetary Policy Report (MPR). Canada’s economy grew by a surprisingly strong 2.6% in the third quarter, even as final domestic demand was flat. The increase in GDP largely reflected volatility in trade. The Bank expects final domestic demand will grow in the fourth quarter, but with an anticipated decline in net exports, GDP will likely be weak. Growth is forecast to pick up in 2026, although uncertainty remains high and large swings in trade may continue to cause quarterly volatility. Canada’s labour market is showing some signs of improvement. Employment has shown solid gains in the past three months and the unemployment rate declined to 6.5% in November. Nevertheless, job markets in trade-sensitive sectors remain weak and economy-wide hiring intentions continue to be subdued. CPI inflation slowed to 2.2% in October, as gasoline prices fell and food prices rose more slowly. CPI inflation has been close to the 2% target for more than a year, while measures of core inflation remain in the range of 2½% to 3%. The Bank assesses that underlying inflation is still around 2½%. In the near term, CPI inflation is likely to be higher due to the effects of last year’s GST/HST holiday on the prices of some goods and services. Looking through this choppiness, the Bank expects ongoing economic slack to roughly offset cost pressures associated with the reconfiguration of trade, keeping CPI inflation close to the 2% target. If inflation and economic activity evolve broadly in line with the October projection, Governing Council sees the current policy rate at about the right level to keep inflation close to 2% while helping the economy through this period of structural adjustment. Uncertainty remains elevated. If the outlook changes, we are prepared to respond. The Bank is focused on ensuring that Canadians continue to have confidence in price stability through this period of global upheaval. Information note The next scheduled date for announcing the overnight rate target is January 28, 2026. The Bank’s next MPR will be released at the same time.

Mortgage Approval 101: GDS & TDS Explained

By Adrian Markiewicz • December 3, 2025
Can You Afford That Mortgage? Let’s Talk About Debt Service Ratios One of the biggest factors lenders look at when deciding whether you qualify for a mortgage is something called your debt service ratios. It’s a financial check-up to make sure you can handle the payments—not just for your new home, but for everything else you owe as well. If you’d rather skip the math and have someone walk through this with you, that’s what I’m here for. But if you like to understand how things work behind the scenes, keep reading. We’re going to break down what these ratios are, how to calculate them, and why they matter when it comes to getting approved. What Are Debt Service Ratios? Debt service ratios measure your ability to manage your financial obligations based on your income. There are two key ratios lenders care about: Gross Debt Service (GDS) This looks at the percentage of your income that would go toward housing expenses only. Total Debt Service (TDS) This includes your housing costs plus all other debt payments—car loans, credit cards, student loans, support payments, etc. How to Calculate GDS and TDS Let’s break down the formulas. GDS Formula: (P + I + T + H + Condo Fees*) ÷ Gross Monthly Income Where: P = Principal I = Interest T = Property Taxes H = Heat Condo fees are usually calculated at 50% of the total amount TDS Formula: (GDS + Monthly Debt Payments) ÷ Gross Monthly Income These ratios tell lenders if your budget is already stretched too thin—or if you’ve got room to safely take on a mortgage. How High Is Too High? Most lenders follow maximum thresholds, especially for insured (high-ratio) mortgages. As of now, those limits are typically: GDS: Max 39% TDS: Max 44% Go above those numbers and your application could be declined, regardless of how confident you feel about your ability to manage the payments. Real-World Example Let’s say you’re earning $90,000 a year, or $7,500 a month. You find a home you love, and the monthly housing costs (mortgage payment, property tax, heat) total $1,700/month. GDS = $1,700 ÷ $7,500 = 22.7% You’re well under the 39% cap—so far, so good. Now factor in your other monthly obligations: Car loan: $300 Child support: $500 Credit card/line of credit payments: $700 Total other debt = $1,500/month Now add that to the $1,700 in housing costs: TDS = $3,200 ÷ $7,500 = 42.7% Uh oh. Even though your GDS looks great, your TDS is just over the 42% limit. That could put your mortgage approval at risk—even if you’re paying similar or higher rent now. What Can You Do? In cases like this, small adjustments can make a big difference: Consolidate or restructure your debts to lower monthly payments Reallocate part of your down payment to reduce high-interest debt Add a co-applicant to increase qualifying income Wait and build savings or credit strength before applying This is where working with an experienced mortgage professional pays off. We can look at your entire financial picture and help you make strategic moves to qualify confidently. Don’t Leave It to Chance Everyone’s situation is different, and debt service ratios aren’t something you want to guess at. The earlier you start the conversation, the more time you’ll have to improve your numbers and boost your chances of approval. If you're wondering how much home you can afford—or want help analyzing your own GDS and TDS—let’s connect. I’d be happy to walk through your numbers and help you build a solid mortgage strategy.
