GDS/TDS Ratios Explained

Rabinder Dhillon • December 25, 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.

How To Improve Your Credit Score

By Rabinder Dhillon • February 19, 2025
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. Get in touch anytime; it would be a pleasure to work with you!

What is a “No-Frills” Mortgage?

By Rabinder Dhillon • February 12, 2025
A no-frills service or product is where non-essential features have been removed from the product or service to keep the price as low as possible. And while keeping costs low at the expense of non-essential features might be okay when choosing something like which grocery store to shop at, which economy car to purchase, or which budget hotel to spend the night, it’s not a good idea when considering which lender to secure mortgage financing. Here’s why. When securing mortgage financing, your goal should be to pay the least amount of money over the term. Your plan should include having provisions for unexpected life changes. Unlike the inconvenience of shopping at a store that doesn’t provide free bags, or driving a car without power windows, or staying at a hotel without any amenities, the so-called “frills” that are stripped away to provide you with the lowest rate mortgage are the very things that could significantly impact your overall cost of borrowing. Depending on the lender, a “no-frills” mortgage rate might be up to 0.20% lower than a fully-featured mortgage. And while this could potentially save you a few hundreds of dollars over a 5-year term, please understand that it could also potentially cost you thousands (if not tens of thousands) of dollars should you need to break your mortgage early. So if you’re considering a “no-frills” mortgage, here are a few of the drawbacks to think through: You'll pay a significantly higher penalty if you need to break your mortgage. You'll have limited pre-payment privileges. Potential limitations if you want to port your mortgage to a different property. You might be limited in your ability to refinance your mortgage (without incurring a considerable penalty). Simply put, a “no-frills” mortgage is an entirely restrictive mortgage that leaves you without any flexibility. There are many reasons you might need to keep your options open. You might need to break your term because of a job loss or marital breakdown, or maybe you decide to take a new job across the country, or you need to buy a property to accommodate your growing family. Life is unpredictable; flexibility matters. So why do banks offer a no-frills mortgage anyway? Well, when you deal with a single bank or financial institution, it’s the banker’s job to make as much money from you as possible, even if that means locking you into a very restrictive mortgage product by offering a rock bottom rate. Banks know that 2 out of 3 people break their mortgage within three years (33 months). However, when you seek the expert advice of an independent mortgage professional, you can expect to see mortgage options from several institutions showcasing mortgage products best suited for your needs. We have your best interest in mind and will help you through the entire process. A mortgage is so much more than just the lowest rate.
