5 Things You Need to Know Before You Co-Sign a Mortgage!

Dan Caird • May 12, 2021

So you’re thinking about co-signing for a mortgage? Okay, do you really know what that means do you know what you are getting yourself into? Co-signing isn’t necessarily a bad thing, but there is certainly a lot of misinformation floating around on the subject. Although it’s nice to be in a position to help someone close to you qualify for a mortgage, It’s not a decision that should be made lightly. Co-signing on a mortgage could have a significant impact on your future.


Here are some things you should consider before co-signing a mortgage application.


1. Regardless if you’re the principal borrower, co-borrower, or co-signor, If you’re on the mortgage, you’re 100% responsible for the debt of the mortgage and everything that goes along with that. Although the term co-signor makes it sound like you are somehow removed from the actual mortgage, you have all the same legal obligations as everyone else on the mortgage.



2. If the person who you’re co-signing for is unable to make the payments for any reason, you will be expected to make them on their behalf. By signing the mortgage documents, you assume full responsibility for the payments (even if it’s not you making them).


3. If payments aren’t being made, there is a chance the lender will take legal action against you. This includes all available collection methods such as obtaining a judgement in court or garnisheeing your wage or bank accounts. Worse case scenario, they could actually go after your property or assets in order to cover their loses. Now, this is highly unlikely, but not out of the realm of possibility.


4. Once the initial term has been completed, you will not automatically be removed from the mortgage. The person who you co-signed for will have to make a new application for the mortgage in their own name and qualify on their own merit. If they don’t qualify at this time, you will be kept on the mortgage for the next term.


5. When you co-sign for a mortgage, all of the debt of the co-signed mortgage is counted against you. This means that if you’re looking to buy another property in the future, you will have to include the payments of the co-signed mortgage in your debt service ratios, even though you aren’t the one making the payments. This could significantly impact the amount you can borrow in the future.


If you have any questions about co-signing on a mortgage, or about the mortgage application process in general, I’d love to discuss it with you. Please don’t hesitate to contact me anytime!

What Lenders Mean by “Good Credit” When You Apply for a Mortgage Credit is simply the ability to borrow money today based on the trust that you’ll repay it in the future. When you apply for a mortgage, lenders want proof that you’ve consistently honoured that trust by managing credit responsibly. But what does a good credit history actually look like to a lender? The 2 / 2 / 2 Rule Explained If you’re newer to credit or want a simple way to remember minimum mortgage credit requirements, think of the 2 / 2 / 2 rule: 2 active trade lines Established for at least 2 years With a minimum combined limit of $2,000 This is a common baseline lenders use when assessing credit for mortgage financing. What Counts as a Trade Line? A trade line is any account where credit is extended to you, such as: A credit card A line of credit A car loan A personal or installment loan Each trade line reports your payment history to the credit bureau and contributes to your credit score. For a trade line to be considered active , it must: Have been used at least once, and Show activity at least once every three months Why Time Matters Lenders want to see that you’ve managed credit responsibly over time , not just recently. Using two trade lines consistently for at least two years helps demonstrate stable financial habits and reliability. Understanding Credit Limits vs. Balances The credit limit is what matters—not the balance. For example: A $1,000 credit card + a $2,500 line of credit = $3,500 total limit This meets the minimum requirement You do not need to carry a balance to build credit. In fact, the best approach is to: Use your credit regularly Pay it off in full each month (for credit cards) Make all loan payments on time If your lender offers a credit limit increase and you’re managing credit well, it’s often a good idea to accept it. Higher limits—used responsibly—can strengthen your credit profile. A Simple Way to Build Credit Automatically One effective strategy is to: Put recurring bills on your credit card Set up an automatic transfer to pay the balance in full every month Automation helps build positive credit history without requiring constant attention—just be sure to monitor your accounts to ensure everything runs smoothly. What About Credit Scores? Yes, credit scores matter—but they’re not the whole story. If you: Have two active trade lines Established for two years With at least $2,000 in total limits And no missed payments …your credit score will generally take care of itself. That said, it’s still wise to review your credit report occasionally to check for errors or unfamiliar accounts. Final Thoughts If you’re thinking about buying a home in the next couple of years, now is the perfect time to review your credit and make sure you’re on track. Small adjustments today can make a big difference when it’s time to apply for a mortgage.
