GDS/TDS Ratios Explained

Stacey Mass • Jul 19, 2023


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 through CMHC is required, the maximum GDS is 35% with a maximum TDS of 42%. Those ratios are stretched a little when default insurance is secured through Sagan (formerly Genworth) or Canada Guarantee to 39% GDS and 44% TDS.


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 Get The Best Mortgage

By Stacey Mass • 08 May, 2024
If you’re looking to buy a property or have a mortgage up for renewal, and you’re thinking about connecting with your bank directly, save yourself a lot of money and regret by reading this article first. Here are four things that your bank won’t tell you, accompanied by four reasons that explain why working with an independent mortgage professional is in your best interest. Banks have Limited Access to Mortgage Products. Now, while this one may seem pretty straightforward, if you’re dealing with a single institution, they can only offer mortgages from their product catalogue. This means that you’ll be restricted to their qualifications which are usually very narrow. Working with a single institution significantly limits your options, especially if your financial situation isn’t straightforward. In contrast, dealing with an independent mortgage professional, you will have access to products from over 200 lenders, including banks, monoline lenders, credit unions, finance companies, alternative lenders, institutional B lenders, Mortgage Investment Corporations, and private funds. Working with an independent mortgage professional will give you considerably more options to secure a better mortgage. Banks Employ Salespeople, not Mortgage Experts. Banks don’t employ mortgage experts; they employ salespeople. Banks pay and incentivize salespeople to sell their products. There is a fundamental misalignment of values here. If the bank incentivizes a banker to make a profit for the bank, how can they at the same time advocate for you and your best interest? They can’t. Banks don’t have your best interest in mind. In fact, the more money they make off of you, the better it is for their bottom line. However, when you work with an independent mortgage professional, you get the experience of someone who understands the intricacies of mortgage financing and will advocate on your behalf to get you the best mortgage. It’s actually in our best interest to assist you in finding the mortgage with the best terms for you. Once your mortgage completes, we get paid a standardized finder’s fee by the lender for arranging the financing. So although we get paid by the lender, that lender has had to compete with other lenders to earn your business. When you work with an independent mortgage professional, everyone wins. You get the best mortgage available, we get paid a standardized finder’s fee, and the lender gets a new borrower. Banks Rarely Offer You Their Best Terms Upfront. Banks are in the business of making money, and they’re usually pretty good at it. As such, banks will rarely offer you their best terms at the outset of your negotiation. This is especially true if you’re looking to refinance your existing mortgage. With over half of Canadians simply accepting the renewal offer they get sent in the mail without question, banks don’t have to put their best rate forward. Instead, they rely on you to be ignorant of the process and will take advantage of your trust in them. When you work with an independent mortgage professional, we don’t play games with rates and terms. Our goal is always to seek out the lender who has the best mortgage for you from the start of the process, and if there are any negotiations to be had, we handle them for you. There is no reason for us to do otherwise. In fact, the better we do our job, the more likely it is that you’ll be happy with our services and refer your friends and family. Banks Promote Restrictive Mortgage Products. As if it’s not bad enough that banks don’t offer their best terms upfront, they actually promote mortgage products that are restrictive in nature. The fine print in your mortgage contract matters; understanding it is challenging. Banks do what they can to make it hard for you to leave. Now, if you’ve ever heard stories of outrageous penalties being charged, this is what’s called an Interest Rate Differential penalty (IRD). Each lender has its own way of calculating the IRD. Chartered banks are known for their restrictive mortgages and high IRD penalties. When you work with an independent mortgage professional, we take the time to listen to your goals and assess your mortgage needs based on your life circumstances. The best mortgage is the one that lowers your overall cost of borrowing. So not only will we walk through the cost of the mortgage financing, but we’ll also clearly outline the costs incurred should you need to break your mortgage before the end of your term. This might be the deciding factor in choosing the right lender and mortgage for you. Working with an Independent Mortgage Professional is in Your Best Interest. Banks have limitations to the mortgage products they offer. Working with an independent mortgage professional gives you mortgage options! Bankers work for the bank; they are incentivized to make money for the bank. An independent mortgage professional advocates on your behalf to get you the best mortgage available. Banks rarely offer their best terms upfront; they leave negotiations up to you. An independent mortgage professional outlines the best terms from multiple lenders at the start of the process. Banks promote restrictive mortgage products that make it difficult to leave them. An independent mortgage broker will outline all the costs associated with different mortgage products and recommend the mortgage best suited for your needs. So if you’d like to talk about the best mortgage product for you, you’ve come to the right place. Please connect anytime. It would be a pleasure to work with you.

Are You Ready To Buy A Home?

By Stacey Mass • 01 May, 2024
Buying your first home is a big deal. And while you may feel like you’re ready to take that step, here are 4 things that will prove it out. 1. You have at least 5% available for a downpayment. To buy your first home, you need to come up with at least 5% for a downpayment. From there, you’ll be expected to have roughly 1.5% of the purchase price set aside for closing costs. If you’ve saved your downpayment by accumulating your own funds, it means you have a positive cash flow which is a good thing. However, if you don’t quite have enough saved up on your own, but you have a family member who is willing to give you a gift to assist you, that works too. 2. You have established credit. Building a credit score takes some time. Before any lender considers you for mortgage financing, they want to see that you have an established history of repaying the money you’ve already borrowed. Typically two trade lines, for a period of two years, with a minimum amount of $2000, should work! Now, if you’ve had some credit issues in the past, it doesn’t mean you aren’t ready to be a homeowner. However, it might mean a little more planning is required! A co-signor can be considered here as well. 3. You have the income to make your mortgage payments. And then some. If you’re going to borrow money to buy a house, the lender wants to make sure that you have the ability to pay it back. Plus interest. The ideal situation is to have a permanent full-time position where you’re past probation. Now, if you rely on any inconsistent forms of income, having a two-year history is required. A good rule of thumb is to keep the costs of homeownership to under a third of your gross income, leaving you with two-thirds of your income to pay for your life. 4. You’ve discussed mortgage financing with a professional. Buying your first home can be quite a process. With all the information available online, it’s hard to know where to start. While you might feel ready, there are lots of steps to take; way more than can be outlined in a simple article like this one. So if you think you’re ready to buy your first home, the best place to start is with a preapproval! Let's discuss your financial situation, talk through your downpayment options, look at your credit score, assess your income and liabilities, and ultimately see what kind of mortgage you can qualify for to become a homeowner! Please connect anytime; it would be a pleasure to work with you!
