Before You Co-Sign a Mortgage

Sarah Hainsworth • April 19, 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.

How Your Loans and Spending Habits Are Quietly Shaping Your Credit Score

Your credit score is one of the most important numbers in your financial life — especially when it comes to getting a mortgage. But for most Canadians, how that number actually gets calculated remains a bit of a mystery.

Buying a Vacation Property or Rental? Here’s What Lenders Look For

By Sarah Hainsworth • April 8, 2026
Owning a vacation home or an investment rental property is a dream for many Canadians. Whether it’s a cottage on the lake for family getaways or a rental unit to generate extra income, real estate can be both a lifestyle choice and a smart financial move. But before you dive in, it’s important to know what lenders look for when financing these types of properties. 1. Down Payment Requirements The biggest difference between buying a primary residence and a vacation or rental property is the down payment. Vacation property (owner-occupied, seasonal, or secondary home): Typically requires at least 5–10% down, depending on the lender and whether the property is winterized and accessible year-round. Rental property: Usually requires a minimum of 20% down. This is because rental income can fluctuate, and lenders want extra security before approving financing. 2. Property Type & Location Not all properties qualify for traditional mortgage financing. Lenders consider: Accessibility : Is the property accessible year-round (roads maintained, utilities available)? Condition : Seasonal or non-winterized cottages may not meet standard lending criteria. Zoning & Use : If it’s a rental, lenders want to ensure it complies with municipal bylaws and zoning regulations. Properties that fall outside these norms may require financing through alternative lenders, often with higher rates but more flexibility. 3. Rental Income Considerations If you’re buying a property with the intent to rent it out, lenders may factor the rental income into your mortgage application. Long-term rentals : Lenders typically accept 50–80% of the expected rental income when calculating your debt-service ratios. Short-term rentals (Airbnb, VRBO, etc.) : Many traditional lenders are cautious about using projected income from short-term rentals. Alternative lenders may be more flexible, depending on the property’s location and your financial profile. 4. Debt-Service Ratios Lenders use your Gross Debt Service (GDS) and Total Debt Service (TDS) ratios to determine if you can handle the mortgage payments alongside your other obligations. With investment or vacation properties, lenders may apply stricter guidelines, especially if your primary residence already carries a large mortgage. 5. Credit & Financial Stability Your credit score, employment history, and overall financial health still matter. Since vacation and rental properties are considered higher risk, lenders want reassurance that you can handle the additional debt—even if rental income fluctuates or the property sits vacant. 6. Insurance Requirements Rental properties often require specialized landlord insurance, and vacation homes may need coverage tailored to seasonal or secondary use. Lenders will want proof of adequate insurance before releasing mortgage funds. The Bottom Line Buying a vacation property or rental can be exciting, but financing these purchases comes with extra rules and considerations. From higher down payments to stricter property requirements, lenders want to be confident that you can handle the responsibility. If you’re considering a second property, the best step is to work with a mortgage professional who can compare lender requirements, outline your options, and find the financing that works best for you.
