Would a Co-Signer Enable You to Qualify for a Mortgage?

Kelly Hudson • October 1, 2024

There seems to be some confusion about what it means to co-sign on a mortgage… and any time there is confusion about mortgages, it’s time to chat with Kelly Hudson, your trusted mortgage expert!! 


Thanks to tighter mortgage qualification rules and higher-priced real estate - particularly in the greater Vancouver and Toronto areas - it is not easy to qualify for a mortgage on your own merits.


Let’s look at why you would want to have someone co-sign your mortgage and what you need to know before, during, and after the co-signing process.


The ‘stress test’ has been especially “stressful” for borrowers.  As of Jan. 1, 2018, all homebuyers need to qualify at the rate negotiated for their mortgage contract PLUS 2% OR the government posted rate which varies (as of Oct. 2024 5.25%), which ever is higher. 


If you have less than 20% down payment, you must purchase Mortgage Default Insurance and qualify at 5.25%. 

  • If you must qualify at a rate higher than what you are paying… then your money doesn’t go as far… and you qualify for a smaller mortgage. 


In the wise words of Mom’s & Dad’s of Canada… “if you can’t afford to buy a home now, then WAIT until you can!!” 


BUT wait… in some housing markets (especially Vancouver & Toronto), waiting it out could easily mean missing out, depending on how quickly property values are appreciating in the area you want to purchase.


If you can’t income qualify for a mortgage with your current provable income along with GREAT credit, your lender’s going to ask for a co-signer. 


In order to give borrowers, the best mortgage rates, Lenders want the best borrowers!! They want someone who will pay their mortgage on time as promised with no hassles.


Co-sign vs Guarantor


Short version:  The main difference between a guarantor and a co-signer is that the co-signer is a title holder and a guarantor is not. However, both individuals are responsible for mortgage payments being made to the lender.


  1. Someone can co-sign your mortgage and become a co-borrower, the same as a spouse or anyone else who you are buying the home with. It’s basically adding the support of another person’s income and credit history to those initially on the application. The co-signer will be put on the title of the home and lenders will consider them equally responsible for the debt should the mortgage go into default.
  2. Another option is a guarantor. If a co-signer decides to become a guarantor, then they’re backing the loan and essentially vouching for the person getting the loan that they’re going to be good for it. The guarantor is going to be responsible for the loan should the borrower go into default.


Most lenders prefer a co-signer going on title. 


More than one person can co-sign a mortgage although it’s typically the parent(s) or a close relative of a borrower who steps up and is willing to put their neck, income, and credit bureau on the line.


Ultimately, if the lender is satisfied that all parties meet the qualification requirements and can lessen the risk of their investment, they’re likely to approve your mortgage.


Before signing on the dotted line


Short Version: A co-signer, in essence, co-owns the home with the individual living in it and paying the mortgage. A co-signer must sign all the mortgage documents and their name will appear on the title of the property. When you co-sign on a mortgage, you become just as responsible for the mortgage loan as the primary borrower — and you can suffer serious consequences if they make late payments or default. 


Anyone that is willing to co-sign a mortgage must be fully vetted, just like the primary applicant(s). They will have to provide all the same documentation as the primary applicant(s). Being a co-signer makes you legally responsible for the mortgage, exactly the same as the primary applicant(s). 


Please note as a Co-signer your future borrowing plans will be affected

  • Since the mortgage will also appear on your credit report, this additional debt could make it tougher for you to qualify for additional credit down the road.
  • For example: if you dreamed of one day owning a vacation home, just know that a lender will have to consider 100% of your co-signed mortgage as part of your overall debt-to-income ratio. 


You are allowing your name and all your information to be used in the process of a mortgage, which is going to affect your ability to borrow anything in the future.


If the Co-signer already owns a home, then they could be charged capital gains on the property they co-signed for IF the property sells for more than the purchase price (contact your accountant for tax advice).


In Canada, capital gains tax is charged on the profit made from selling real estate, including homes, for more than their purchase price. 


However, there is an exemption for primary residences. If the home was your primary residence for the entire period of ownership, you are generally
exempt from paying capital gains tax on the sale. 

  • A primary residence is where you or your family lived most of the time, and only one property per family can be designated as such per year.


This gets complicated for co-signers – since they rarely live in the home they are co-signing for.


For non-primary residences, (rental, investment properties, co-signed properties) capital gains tax applies to the profit made from the sale. In Canada, the CRA taxes 50% of gains up to $250,000, and 66.7% of gains over $250,000.

  • For example, selling a rental property that you purchased for $300K and sold for $400K would result in a $100K capital gain.


Typically, we’ll put the co-signer(s) on title for the home/mortgage at 1% of home ownership... then IF there were a capital gain, they would pay 1% of their share of the capital gain (contact your accountant for tax advice).



If someone is a guarantor, then things can become even trickier as the guarantor isn’t on title to the home. That means that even though they are on the mortgage, they have no legal right to the home itself. If anything happens to the original borrower, where they die, or something happens, they’re not on the title of that property but they’ve signed up for the mortgage. 

  • The Guarantor doesn’t have a lot of control which can be a scary thing.


In my opinion, it’s much better for a co-signer to be a co-borrower on the property, where you can be on title to the property and enjoy all the legal rights afforded to you.


The Responsibilities of Being a Co-signer


Co-signing can really help someone out, but it’s also a big responsibility. When you co-sign for someone, you’re putting your name and credit on the line as security for the loan/mortgage.


If the person you co-sign for misses a payment, the lender or other creditor can come after you to get their money. Any late mortgage payments would also show up on your credit report, which could impact your own loan/mortgage qualification in the future.


Because co-signing a loan has the potential to affect both your credit and finances, it’s extremely important to make sure you’re comfortable with the person you’re co-signing for. 

  • You both need to know what you’re getting into. 


I recommend Independent Legal Advice between all co-borrowers.


Co-signing is NOT a life sentence. 


Just because you need a co-signer to get a mortgage does not mean that you will always need a co-signer.


In fact, as soon as you can credit & income qualify for the mortgage on your own (without your co-signer) – you can ask your lender to remove the co-signer from title. 

  • It is a legal procedure so there will be a cost associated with the process, but doing so will remove the co-signer from your mortgage loan and release them from the responsibility of your mortgage.


Removing a co-signer technically counts as changing the mortgage, so you need to ensure that the lender you chose doesn’t consider removing a co-signer (changing the covenant) as breaking your mortgage.  There could be large penalties associated with doing so. 



Co-signing is an option that could help a lot of people buy a home, especially first-time home buyers who are typically starting their career and building their credit bureau.


A final mortgage tip: a few alternatives to co-signing that could help someone buy a home:

  • Providing funds for a gifted down payment
  • NOT a loan – a gift.  The person providing the gift would need to sign a Gift Letter stating that the money is a gift and there is no repayment required.
  • Helping to pay off some OR better yet all their debt (i.e., credit cards, loans, lines of credit, student loans etc.)
  • Giving them additional funds to help pay the mortgage/home owning expenses.


Are you considering at buying a home? 


As you can tell there is lots to discuss, let’s have a chat and find a mortgage that works for you and not the bank.

Reverse mortgage ad with smiling couple, house, flowers, and question marks about using home equity
By Kelly Hudson • October 9, 2026
For many Canadians, their home is their biggest financial asset. After years of homeownership, they may have paid off most (or all) or all their mortgage and built a lot of equity in their home. The problem: You can own a valuable home and still struggle to pay your monthly bills. You've probably heard the phrase “house rich and cash poor.” This is exactly what it means. For Canadian homeowners aged 55 and older, a reverse mortgage is one option worth looking at. It's definitely NOT the right solution for everyone. But for some homeowners, it can provide extra cash while allowing them to stay in the home they love. What Is a Reverse Mortgage? A reverse mortgage allows homeowners 55+ to access some of the equity in their home without selling it. Unlike a regular mortgage, you don't normally have to make monthly mortgage payments. Instead, interest is added to the amount you borrowed, so the balance grows over time. The mortgage is typically repaid when the home is sold, the homeowners permanently move out, or the last homeowner dies. And one of the biggest misconceptions I hear? The bank does NOT own your home. You do. You stay on title and continue to own your home. The money you receive is also generally tax-free because you're borrowing the money - it's not income. What Does “House Rich, Cash Poor” Look Like? Let's say you've lived in your home for 30 years. Your mortgage is paid off and your home is now worth $1 million. Sounds pretty good, right? But your retirement income may come from CPP, OAS, a pension and your savings. At the same time, groceries, property taxes, insurance, utilities and everything else seem to keep getting more expensive. So, while you may have hundreds of thousands of dollars in home equity, your monthly budget can still feel tight. You have the money. It's just tied up in your house. A reverse mortgage is one way to access some of that equity without having to sell and move. What Could You Use the Money For? There are generally no restrictions on how you use the money. Everyone's situation is different, but I've seen homeowners consider a reverse mortgage to: Pay off an existing mortgage, credit cards or other debts Add to your monthly retirement income Make home repairs or accessibility upgrades so you can stay in your home longer Pay for in-home care Help children or grandchildren financially Cover unexpected expenses or create an emergency fund Depending on the product, you may also have choices about how and when you receive the money. You don't necessarily have to take everything at once. Why Not Just Sell and Downsize? This is usually one of the first alternatives we talk about. Downsizing can make perfect sense—but it's not always as easy or as inexpensive as people think. A smaller home or condo can still be expensive, especially in many BC communities. Then add real estate commissions, legal fees, moving expenses, strata fees and other costs. And there's another part of this decision that has nothing to do with numbers. Your home is more than an asset on a balance sheet. Maybe you've lived there for 30 years. Your friends are nearby. You know your neighbours. Your doctor, family and community are close. Maybe you simply love your home and don't want to move. For many retirees, being able to stay in their home is an important part of their retirement plan. So... What's the Catch? There isn't any free money here. Reverse mortgage rates are typically higher than traditional mortgage rates. And because you aren't making regular mortgage payments, the interest gets added to the amount you borrowed. That means the amount you owe grows over time and the equity left in your home can decrease. There can also be appraisal, legal, setup and closing costs. Depending on the mortgage and when you repay it, there may also be a penalty. And remember—you still own the house. That means you're still responsible for maintaining it, keeping it insured and paying the property taxes. That's why it's important to look beyond the interest rate and understand the long-term costs. What About My Children's Inheritance? This is a conversation worth having with your family. A reverse mortgage will normally mean there is less equity left in your home for your estate. For some homeowners, leaving as much as possible to their children is extremely important. Others look at it differently. They would rather use some of the equity they've spent decades building to make their own retirement more comfortable. And some parents decide they'd rather help their children or grandchildren now , while they're still here to see them enjoy it (i.e. a gifted down payment). There's no right or wrong answer. It's your home, your equity and your decision. Reverse Mortgage or Home Equity Line of Credit (HELOC) ? A HELOC is another way to access the equity in your home. But there's an important difference. With a HELOC, you need enough income to qualify, and you'll need to make monthly payments. That can be difficult for someone who is retired and has a valuable home but limited monthly income. A reverse mortgage works differently because it's designed for older homeowners. One option isn't automatically better than the other. Maybe a HELOC makes more sense. Maybe refinancing makes more sense. Maybe a reverse mortgage does. It depends on your income, age, equity, monthly cash flow and, most importantly, what you're trying to accomplish. Is a Reverse Mortgage Right for You? 
Infographic on Canadian mortgage lending ratios, with house icons, GDS, TDS, and “How Much Mortgage Can You Afford?” text
By Kelly Hudson • September 16, 2026
If you're thinking about buying a home in BC, one of the first questions you probably have is: How much mortgage can I qualify for? Your income is certainly important, but it isn't the only number a mortgage lender looks at. Lenders also consider your debts, credit history, down payment, property costs and something called your mortgage lending ratios . The two ratios you'll hear about most often are GDS (Gross Debt Service) and TDS (Total Debt Service) . The names sound complicated. The math really isn't. Understanding how GDS and TDS work can give you a much better idea of what you may qualify for — and why two people earning the same income could qualify for very different mortgage amounts.
