GDS/TDS Ratios Explained

Lisa Manwaring • August 7, 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.

Benefits of Working with an Independent Mortgage Professional

By Lisa Manwaring • February 19, 2025

If you need a mortgage, working with an independent mortgage professional will save you money and provide you with better options than dealing with a single financial institution. And if that is the only sentence you read in this entire article, you already know all you need to know. However, if you’d like to dig a little deeper, here are some reasons that outline why working with an independent mortgage professional is in your best interest. The best mortgage is the one that costs you the least over the long term. An independent mortgage professional can help you achieve this. Mortgages aren’t created equally. Oftentimes slick marketing leads us to believe the lowest “sticker price” is the best value. So when it comes to mortgage financing, you might assume the mortgage with the lowest rate is the best option. This isn’t always the case. When considering a mortgage, your goal should be to find the mortgage that will cost you the least amount of money over the total length of the mortgage. There are many factors to consider, such as your specific financial situation, the rate, initial term length, fixed or variable rate structure, amortization, and the penalties incurred should you need to break your mortgage early; the fine print matters. An independent mortgage professional can walk through all these factors with you and will help you find the mortgage that best suits your needs. Sometimes taking a mortgage with a slightly higher rate can make sense if it gives you flexibility down the line or helps you avoid huge payout penalties. Working the numbers with an independent mortgage professional will save you money in the long run instead of just going with what a single lender is offering. Save time by letting an independent mortgage professional find the best mortgage product for you. Let's face it, getting a mortgage can be challenging enough on its own. Everyone’s financial situation is a little different and making sense of lender guidelines is a full-time job in itself. So instead of dealing with multiple lending institutions on your own, when you work with an independent mortgage professional, you submit a single mortgage application that is compared to the lending guidelines of various mortgage lenders. This will save you time as you don’t have to go from bank to bank to ensure you’re getting the best mortgage. Simply put, an independent mortgage professional works for you and has your best interest in mind, while a bank specialist works for the bank and has the bank's best interest in mind. It’s no secret that Canadian banks make a lot of money. It seems every quarter they turn billions of dollars in profit (despite the economic environment). They do this at the expense of their customers by charging as much interest as they can and structuring mortgages to their benefit. It’s all about the alignment of interest. Bank employees work for the bank; the bank pays them to make money for the bank. In contrast, independent mortgage professionals are provincially licensed to work for their clients and are paid a standardized placement or finder’s fee for matching borrowers with lenders. When you work with a single bank, you only have access to the products of that bank. When you work with an independent mortgage professional, you have access to all of the lenders that mortgage professionals have relationships with and all their products. Working with an independent mortgage professional will save you money, time, and provide you with better mortgage options. Plus, you have the added benefit of working with a licensed professional looking out for your best interest, providing you with the best possible advice.

Costs Associated with Buying Property

By Lisa Manwaring • February 12, 2025

When calculating if you can afford to purchase a property, don’t just figure out a rough downpayment and quickly move on from there. Several other costs need to be considered when buying a property; these are called your closing costs. Closing costs refer to the things you’ll have to pay for out of your pocket and the amount of money necessary to finalize the purchase of a property. And like most things in life, it pays to plan ahead when it comes to closing costs. Closing costs should be part of the pre-approval conversation as they are just as important as saving for your downpayment. Now, if your mortgage is high-ratio and requires mortgage default insurance, the lender will need to confirm that you have at least 1.5% of the purchase price available to close the mortgage. This is in addition to your downpayment. So if your downpayment is 10% of the purchase price, you’ll want to have at least 11.5% available to bring everything together. But of course, the more cash you have to fall back on, the better. So with that said, here is a list of the things that will cost you money when you’re buying a property. As prices vary per service, if you’d like a more accurate estimate of costs, please connect anytime, it would be a pleasure to walk through the exact numbers with you. Inspection or Appraisal A home inspection is when you hire a professional to assess the property's condition to make sure that you won’t be surprised by unexpected issues. An appraisal is when you hire a professional to compare the property's value against other properties that have recently sold in the area. The cost of a home inspection is yours, while the appraisal cost is sometimes covered by your mortgage default insurance and sometimes covered by you! Lawyer or Notary Fees To handle all the legal paperwork, you’re required to hire a legal real estate professional. They’ll be responsible for transferring the title from the seller's name into your name and make sure the lender is registered correctly on the title. Chances are, this will be one of your most significant expenses, except if you live in a province with a property transfer tax. Taxes Depending on which province you live in and the purchase price of the property you’re buying, you might have to pay a property transfer tax or land transfer tax. This cost can be high, upwards of 1-2% of the purchase price. So you’ll want to know the numbers well ahead of time. Insurance Before you can close on mortgage financing, all financial institutions want to see that you have property/home insurance in place for when you take possession. If disaster strikes and something happens to the property, your lender must be listed on your insurance policy. Unlike property insurance, which is mandatory, you might also consider mortgage insurance, life insurance, or a disability insurance policy that protects you in case of unforeseen events. Not necessary, but worth a conversation. Moving Expenses Congratulations, you just bought a new property; now you have to get all your stuff there! Don’t underestimate the cost of moving. If you’re moving across the country, the cost of hiring a moving company is steep, while renting a moving truck is a little more reasonable; it all adds up. Hopefully, if you’re moving locally, your costs amount to gas money and pizza for friends. Utilities Hooking up new services to a property is more time-consuming than costly. However, if you’re moving to a new province or don’t have a history of paying utilities, you might be required to come up with a deposit for services. It doesn’t really make sense to buy a property if you can’t afford to turn on the power or connect the water. So there you have it; this covers most of the costs associated with buying a new property. However, this list is by no means exhaustive, but as mentioned earlier, planning for these costs is a good idea and should be part of the pre-approval process.
