Before You Co-Sign a Mortgage

Wyatt Tunnicliffe • November 27, 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.

How Property Type and Condition Influence Mortgage Financing

By Wyatt Tunnicliffe • August 5, 2026
Why the Property Matters When You’re Qualifying for a Mortgage When qualifying for a mortgage, lenders typically look at four core areas: Income Credit Down payment or equity The property itself Most buyers focus heavily on income, credit, and savings—and for good reason. But even if those boxes are checked, the property can still determine whether a mortgage is approved. Why Lenders Care About the Property From a lender’s perspective, the property is the collateral for the mortgage. In the unlikely event of default, they need to know the home can be sold quickly and at fair market value to recover their funds. Because of this, lenders are careful about the condition, value, and marketability of any property they finance. Homes that are in poor repair, unconventional, or overpriced can raise red flags—even when the borrower is well qualified. Appraisals Are Always Part of the Process Every mortgage requires an appraisal to confirm value. Insured mortgages (through CMHC, Sagen, or Canada Guaranty) often use an automated valuation model completed online. Conventional mortgages typically require a full, on-site appraisal by a certified appraiser. This appraisal is not optional and happens after an offer is accepted—not at the pre-approval stage. Why Pre-Approvals Aren’t a Guarantee A pre-approval is a great first step, but it only assesses you, not the property. Once you’ve made an offer, the lender must approve the specific home you’re buying. Understanding this upfront helps avoid surprises and confusion later in the process. The Risk of Buying Without a Financing Condition In competitive markets, buyers sometimes remove financing conditions to strengthen their offer. However, this comes with risk. If the appraisal comes back low—or the lender is concerned about the property’s condition—you could be denied financing after the offer is firm. In that scenario, your deposit may be at risk. Buying a Home That Needs Work If you’re considering a property that isn’t in perfect condition, there are solutions. A purchase plus improvements program allows you to buy a home and include renovation costs in your mortgage. The process is structured and requires planning, but it can be an excellent way to turn a fixer-upper into a great long-term investment. Final Thoughts Mortgage approval isn’t based solely on your finances—the property matters just as much. Knowing this ahead of time helps you make smarter offers, reduce risk, and plan more effectively. If you’re buying a property that needs work or want clarity on how a lender may view a specific home, feel free to reach out.

Need Funds Between Buying and Selling? Here’s How Deposit Loans & Bridge Financing Help

By Wyatt Tunnicliffe • July 29, 2026
You’ve outgrown your current home. It no longer fits your life, so moving makes sense. And you’re not interested in juggling two properties. Selling first and buying something new feels like the right move. Ideally, you want possession of the new home before leaving the old one. That overlap makes moving easier, reduces stress, and gives you time to paint, renovate, or settle in before the boxes arrive. But there’s a common challenge. What if the down payment for your next home is tied up in the equity of the one you’re selling? That’s where bridge financing comes in. How bridge financing works Bridge financing temporarily unlocks equity from your current home once it has a firm sale . It bridges the gap between selling your existing property and purchasing your next one, allowing you to use that equity toward your down payment. What about competitive markets? In a hot market, a strong offer often means a larger deposit . If you don’t have that cash sitting in your account, but you do have equity, a deposit loan can help you compete with confidence. The non-negotiable requirement To qualify for bridge financing or a deposit loan, your current home must have a firm, unconditional sale . No firm sale = no bridge or deposit loan. Lenders need certainty to calculate available equity and manage risk. Bottom line A firm sale is the key that unlocks bridge financing and deposit loans. If you’re planning a move and want to understand how these options could work for you, let’s talk. I’m always happy to walk you through your options and help you plan your next step with confidence.
