What is a Second Mortgage?

Susan Au-Young • November 11, 2025

If you're not all that familiar with the ins and outs of mortgage financing, the term "second mortgage" might cause a bit of confusion. Many people incorrectly assume that a second mortgage is arranged when your first term is up for renewal or when you sell your first home. They think that the next mortgage you get is your "second mortgage." This is not the case.


A second mortgage is an additional mortgage on a single property, not the second mortgage you get in your lifetime.


When you borrow money to buy a house, your lawyer or notary will register your mortgage on the property title in what is called first position. This means that your mortgage lender has the first claim against the sale proceeds if you sell your property. If you happen to default on your mortgage, this is the security the lender has in repossessing your property. A second mortgage falls in behind the first mortgage on your property title.


When you sell your property, the lawyers will use the sale proceeds to pay off your mortgages in sequence, the first position mortgage is paid out first, and the second mortgage is paid out second. After both mortgages are paid off completely, you get the remaining equity.


When you secure a second mortgage, you continue making payments on your first mortgage as per your mortgage agreement. You must also then fulfill the terms of the second mortgage. 


So why would you want a second mortgage? Well, a second mortgage comes in handy when you're looking to access some of your home equity, but you either have excellent terms on your first mortgage that you don't want to break, or you’d incur a huge penalty to break your first mortgage. Instead of refinancing the first mortgage, a second mortgage can be a better option. 


A second mortgage is often used as a short-term debt consolidation tool to help provide you with better cash flow. If you’ve accumulated a considerable amount of high-interest unsecured debt, and you have equity in your home, you can secure a second mortgage to lower your overall cost of borrowing.

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.

If you’re looking to do some home renovations but don’t have all the cash up front to pay for materials and contractors, here are a few ways to use mortgage financing to bring everything together. Existing Home Owners - Mortgage Refinance Probably the most straightforward solution, if you’re an existing homeowner, would be to access home equity through a mortgage refinance. Depending on the terms of your existing mortgage, a mid-term mortgage refinance might make good financial sense; there’s even a chance of lowering your overall cost of borrowing while adding the cost of the renovations to your mortgage. As your financial situation is unique, it never hurts to have the conversation, run the numbers, and look at your options. Let’s talk! If you're not in a huge rush, it might be worth waiting until your existing term is up for renewal. This is a great time to refinance as you won’t incur a penalty to break your existing mortgage. Now, regardless of when you refinance, mid-term or at renewal, you’re able to access up to 80% of the appraised value of your home, assuming you qualify for the increased mortgage amount. Home Equity Line of Credit Instead of talking with a bank about an unsecured line of credit, if you have significant home equity, a home equity line of credit (HELOC) could be a better option for you. An unsecured line of credit usually comes with a pretty high rate. In contrast, a HELOC uses your home as collateral, allowing the lender to give you considerably more favourable terms. There are several different ways to use a HELOC, so if you’d like to talk more about what this could look like for you, connect anytime! Buying a Property - Purchase Plus Improvements If you’re looking to purchase a property that could use some work, some lenders will allow you to add extra money to your mortgage to cover the cost of renovations. This is called a purchase plus improvements. The key thing to keep in mind is that the renovations must increase the value of the property. There is a process to follow and a lot of details to go over, but we can do this together.
