GDS/TDS Ratios Explained

Mike Havery • Mar 20, 2024

One of the major qualifiers lenders look at when considering your application for mortgage financing is your debt service ratios.


Now, before we get started, if you prefer to have someone walk through these calculations with you, assess your financial situation, and let you know exactly where you stand, let’s connect. There is no use in dusting off the calculator and running the numbers yourself when we can do it for you!


However, if you’re someone who likes to know the nitty-gritty of how things work instead of simply accepting that's just the way it is, this article is for you. But be warned, there are a lot of mortgage words and some math ahead; with that out of the way, let’s get started!

 

“Debt servicing” is the measure of your ability to meet all of your financial obligations. There are two ratios that lenders examine to determine whether you can debt service a mortgage.


The first is called the “gross debt service” ratio, or GDS, which is the percentage of your monthly household income that covers your housing costs. The second is called the “total debt service” ratio, or TDS, which is the percentage of your monthly household income covering your housing costs and all your other debts.


GDS is your income compared to the cost of financing the mortgage, including your proposed mortgage payments (principal and interest), property taxes, and heat (PITH), plus a percentage of your condo fees (if applicable).


Here’s how to calculate your GDS.


Principal + Interest + Taxes + Heat / Gross Annual Income


Your TDS is your income compared to your GDS plus the payments made to service any existing debts. Debts include car loans, line of credit, credit card payments, support payments, student loans, and anywhere else you’re contractually obligated to make payments.


Here’s how to calculate your TDS.


Principal + Interest + Taxes + Heat + Other Debts / Gross Annual Income


With the calculations for those ratios in place, the next step is to understand that each lender has guidelines that outline a maximum GDS/TDS. Exceeding these guidelines will result in your mortgage application being declined, so the lower your GDS/TDS, the better.


If you don’t have any outstanding debts, your GDS and TDS will be the same number. This is a good thing!


The maximum ratios vary for conventional mortgage financing based on the lender and mortgage product being offered. However, if your mortgage is high ratio and mortgage default insurance is required, the maximum GDS is 39% with a maximum TDS of 44%.


So how does this play out in real life? Well, let’s say you’re currently looking to purchase a property with a payment of $1700/mth (PITH), and your total annual household income is $90,000 ($7500/mth). The calculations would be $1700 divided by $7500, which equals 0.227, giving you a gross debt service ratio of 22.7%.


A point of clarity here. When calculating the principal and interest portion of the payment, the Government of Canada has instituted a stress test. It requires you to qualify using the government's qualifying rate (which is higher), not the actual contract rate. This is true for both fixed and variable rate mortgages.


Now let’s continue with the scenario. Let’s say that in addition to the payments required to service the property, you have a car payment of $300/mth, child support payments of $500/mth, and between your credit cards and line of credit, you’re responsible for another $700/mth. In total, you pay $1500/mth. So when you add in the $1700/mth PITH, you arrive at a total of $3200/mth for all of your financial obligations. $3200 divided by $7500 equals 0.427, giving you a total debt service ratio of 42.7%.


Here’s where it gets interesting. Based on your GDS alone, you can easily afford the property. But when you factor in all your other expenses, the TDS exceeds the allowable limit of 42% (for an insured mortgage anyway). So why does this matter? Well, as it stands, you wouldn’t qualify for the mortgage, even though you are likely paying more than $1700/mth in rent.


So then, to qualify, it might be as simple as shuffling some of your debt to lower payments. Or maybe you have 10% of the purchase price saved for a downpayment, changing the mortgage structure to 5% down and using the additional 5% to pay out a portion of your debt might be the difference you need to bring it all together.


Here’s the thing, as your actual financial situation is most likely different than the one above, working with an independent mortgage professional is the best way to give yourself options. Don’t do this alone. Your best plan is to seek and rely on the advice provided by an experienced independent mortgage professional. While you might secure a handful of mortgages over your lifetime, we do this every day with people just like you.


It’s never too early to start the conversation about mortgage qualification. Going over your application and assessing your debt service ratios in detail beforehand gives you the time needed to make the financial moves necessary to put yourself in the best financial position.


So if you find yourself questioning what you can afford or if you want to discuss your GDS/TDS ratios to understand the mortgage process a little better, please get in touch. It would be a pleasure to work with you, we can get a preapproval started right away.

Unsure About the Housing Market? Let's Talk.

By Mike Havery • 08 May, 2024
If you’ve been thinking about buying a property, whether that be your first home, next home, forever home, or a home to retire into, the current state of the Canadian economy might have you wondering: Is this really the right time to make a move? There is certainly no shortage of doom and gloom in the news out there. The truth is, that’s a tough question to answer in the best of times. It’s nearly impossible to know for sure what’s going to happen next with the housing market in Canada. It could heat up or it could cool down. So here’s some advice. Instead of basing your buying decision entirely on external market factors, like the economy or housing market, consider looking for the answers internally. When you stop looking at the market to determine your timing to buy a home, and instead examine the personal reasons you have for wanting to buy a home, the picture can become much clearer. Here are some questions to consider. Although they are subjective, they will help bring you clarity. Ask yourself: Does buying a property now put me in a better financial position? Do I make enough money now to afford a new home and maintain my lifestyle? Do I feel confident with my current employment status? Have I saved enough money for a down payment? How long do I plan on living in this new home? Is there any scenario where I might have to sell quickly and potentially lose money? Does buying a property now move me closer to my life goals? Do I really want to buy now or am I just feeling a lot of pressure to just buy something? Am I holding back because I'm scared property prices might drop soon? There’s no doubt that buying a home can be stressful, but it doesn’t have to be. Having a plan in place is the best course of action to help you make good decisions and alleviate that stress. If you’d like to have a conversation to discuss your plans, ask some questions, and map out what buying a home looks like for you, we can address many of the unknowns together. The best place to start is to work through a mortgage pre-approval. There is no cost for this service, you’ll learn exactly what you can qualify for, and it will provide a lot of clarity about your situation. You might decide that it’s best to wait before buying, and that’s just fine. You might find that now’s a perfect time for you to buy! If you'd like to talk, please connect anytime. You’re not in this alone. We can work through everything together.

Improving Your Credit Score

By Mike Havery • 01 May, 2024
Your credit score and how you manage credit are huge factors in qualifying for a mortgage. If you want the best interest rates and mortgage products available on the market, you want a high credit score. Here are a few things you can do to improve your credit score. Make all your payments on time. Making your payments on time is so important; in fact, it might just be the most important factor in managing your credit. Here's how credit works. When you borrow money from a lender, you agree to make payments with interest on a set schedule until the debt is repaid in full. Good credit is established and maintained by making your payments on time. However, If you break the terms of that schedule by not making your payments, the lender will report the missed payments to the credit reporting agencies, and your credit score suffers. It’s that simple. The more payments you miss, the lower your score will be. If you fail to make payments for over 120 days, the lender will most likely send your debt to be recovered by a collection agency. Collections stay on your report for a long time. So the moment you realize you have missed a payment or as soon as you have the money for it, make the payment. If something prevents you from making a payment, consider contacting the lender directly to let them know what happened and work out an arrangement to make the payment as soon as possible. It's good to note that lenders only report late payments after a payment is 30 days late. If you miss a payment on a Friday and catch it the following Monday, you won't have anything to worry about - except maybe an NSF fee. Now, just because payments don't report until being 30 days late, don’t get comfortable with making late payments; the best advice is to pay your debts on time, as agreed. Stop acquiring new credit. If you already have at least two different trade lines, you shouldn’t acquire new trade lines just for the sake of it. Of course, if you need to borrow money, like to purchase a vehicle to commute to work, go ahead and apply. Just remember: having more credit available to you doesn’t really help your credit score. In fact, each time a potential lender looks at your credit report, it may lower your credit score a little bit. With that said, if you already have two different trade lines and your lender offers you an increase on your limit, take it. A credit card with a $10k limit is better for you than a credit card with a $2k limit because how much you spend compared to your credit card's limit impacts your credit score. This leads us directly into the next point. Keep a reasonable balance. The more credit you use compared to the limit you have, the less creditworthy you appear. It’s better to carry a reasonable balance (15-25% of the card’s limit) and pay it off each month than to max out your credit cards and just make the minimum payments. If you have to spend more than 25% of your card limit, try to remain under 60%. That shows good utilization. Paying down your credit cards every month and carrying a zero balance will undoubtedly improve your credit score. Check your credit report regularly. Did you know that roughly 20% of credit reports have misinformation on them? Mistakes happen all the time. Lenders misreport information, or people with the same names get merged reports. Any number of things could be inaccurate without you knowing about it. You might even have become a victim of fraud or identity theft. By checking your credit regularly, you can stay on top of everything and correct any errors promptly. Both of Canada's credit reporting agencies, Equifax and Transunion, have programs that, for a small fee, will monitor and update you on any changes made to your credit report. Handle collections immediately. When checking your credit report for accuracy, if you happen to find a collection has been registered against you, deal with it immediately. It could be a closed-out cell phone account with a small balance owing, a final utility bill that got missed, unpaid parking tickets, wage garnishments, or spousal support payments. Regardless of what it is, it will harm your credit score if it's registered on your credit report. The best plan of action is to handle any collections or delinquent accounts as soon as possible. Use your credit card. If you have acquired credit cards to build your credit score, but you rarely use them, there is a chance the lender might not report your usage, and that won’t help your credit score. You'll want to make sure that you use your credit at least once every three months. Many people find success using their credit cards for gas and groceries and paying off the outstanding balance each month. There you have it. Regardless of what your credit looks like now, you will continue to increase your credit score if you follow the points outlined above. If you're looking to buy a property and you’d like to work through your credit report in detail, let’s put together a plan to get you qualified for a mortgage.
