Before You Co-Sign a Mortgage

Tanya Toye • November 26, 2025

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.

Deposit vs. Down Payment: Key Differences for Homebuyers

By Tanya Toye • September 23, 2026
When you’re buying a home, two terms often cause confusion: deposit and down payment . While they’re related, they serve very different purposes in the homebuying process. Here’s what you need to know. What Is a Deposit? A deposit is the money you provide when you make an offer on a property. Think of it as a show of good faith that proves you’re serious about purchasing. How it works : Typically, you provide a certified cheque or bank draft that your real estate brokerage holds in trust. If your offer is accepted, the deposit remains in trust until the deal moves forward. If negotiations fall through, the deposit is refunded. Connection to your down payment : Once the sale is finalized, your deposit becomes part of your total down payment. Why it matters : The amount is negotiable, but a larger deposit can make your offer more attractive in a competitive market. Keep in mind, however, that if you back out after conditions are removed, you risk losing your deposit. What Is a Down Payment? Your down payment is the amount you contribute toward the purchase price of your home when securing a mortgage. Minimum requirement : In Canada, the minimum down payment is 5% of the home’s purchase price. Anything less than 20% requires mortgage default insurance. Sources : Down payments can come from your savings, the sale of another property, RRSP withdrawals (through the Home Buyers’ Plan), a gift from family, or even borrowed funds. Example: How They Work Together Imagine you’re buying a $400,000 home with a 10% down payment ($40,000). When you make your offer, you provide a $10,000 deposit . Once conditions are met, that deposit is transferred to your lawyer’s trust account. At closing, you add the remaining $30,000 to complete your full down payment. The lender provides the rest—$360,000—through your mortgage. The Bottom Line Your deposit shows commitment and secures your offer, while your down payment is what makes the mortgage possible. Together, they work hand in hand to get you into your new home. 📞 If you’d like clarity on deposits, down payments, or any other part of the mortgage process, let’s connect.

Self-Employed? Let’s Get You Qualified for a Mortgage

By Tanya Toye • September 16, 2026
Being self-employed comes with plenty of advantages, including the ability to structure your business how you choose and claim expenses to reduce your taxable income. But, when it comes time to apply for a mortgage, those same tax strategies can sometimes make qualifying more complicated. One of the first considerations is how your business is structured. There can be differences in how lenders assess income for someone who is incorporated compared with someone who operates as a sole proprietor or partnership. Depending on the lender and the circumstances, income may be reviewed using personal tax returns, corporate financial statements or a combination of documents. Another important factor is the level of business write-offs you claim. As a business owner, reducing your taxable income can make good financial sense. However, a lower reported income can also mean a lower qualifying income when a lender assesses your mortgage application. This can create a frustrating situation where you may have strong cashflow and the ability to comfortably afford the mortgage, but your tax returns don’t necessarily tell the whole story. That doesn’t automatically mean you need to start declaring significantly more income and paying substantially more to the CRA just so you can qualify for a mortgage. Alternative mortgage solutions may be a great option Depending on your circumstances, there may be alternative mortgage solutions available that take a broader view of your financial situation. Some lenders have different approaches to self-employed income and may be able to consider additional documentation or alternate methods of demonstrating your ability to repay the mortgage.  This can create an important financial decision for self-employed borrowers. Is it more beneficial to pay additional taxes to show a higher income or consider a mortgage option with a higher interest rate that may allow you to qualify based on your existing financial structure? There isn’t a one-size-fits-all answer. The right approach depends on your income, business structure, financial goals, credit profile, down payment and how long you expect to be in that mortgage. The key is to have the conversation before you make changes to how you report your income. A mortgage broker who understands self-employed borrowers can help you explore your options and compare the potential costs of different approaches. Instead of assuming you need to change the way you run your business to qualify for a mortgage, it may be worth looking at the lending solutions available to you first. Being self-employed shouldn’t automatically make getting a mortgage more difficult. It just means your mortgage strategy may need to be as individual as your business.
