How to Ensure a Smooth Home Purchase

Tim Lyon • March 20, 2025

Chances are, buying a home is one of the most important financial decisions you’ll make in your life. And as mortgage financing can be somewhat confusing at the best of times, to alleviate some of the stress and to ensure your home purchase goes as smoothly as possible, here are six very high-level steps you should follow.


While it might seem like the best place to start the home buying process is to browse MLS on your phone and then contact a Realtor to go out and look at properties, it’s not. First, you’re going to want to work with a licensed independent mortgage professional.


When you work with an independent mortgage professional, instead of working with a single bank, you’ll be working with someone who has your best interest in mind and can present you with mortgage options from several financial institutions.


The second step in the home buying process is to put together a mortgage plan. Unless you have enough money in the bank to buy a home with cash, you’re going to need a mortgage. And as mortgage financing can be challenging and not so straightforward, the best time to start planning for a mortgage is right now. Don’t make another move until you discuss your financial situation with an independent mortgage professional. It’s never too early to start planning.


As part of your mortgage plan, you’ll want to figure out what you can afford on paper, assess your credit score, run some financial scenarios, calculate mortgage payments, and have a clear picture of exactly how much money is required for a downpayment and closing costs. You’ll also be able to discuss which mortgage product is best for you, considering different mortgage terms, types, amortizations, and features.


Now, what you qualify to borrow on paper doesn’t necessarily mean you can actually afford the payments in real life. You need to consider your lifestyle and what you spend your money on. Understanding your cash flow is the key. Make a budget to verify you can actually afford your proposed mortgage payments and that you have enough funds to close on the mortgage. No one wants to be house-poor or left scrambling to come up with funds to close at the last minute.


If everything looks good at this point, the next step will be to get a preapproval in place. Now, a pre-approval is more than just typing some numbers into a form or online calculator; you need to complete a mortgage application and submit all the documents requested by your mortgage professional.


Only proceed with looking at properties when you’ve been given the green light from your mortgage professional. When you’ve found a property to purchase, you’ll work very closely with your mortgage professional to arrange mortgage financing in a short period of time. This is where being prepared pays off.


As you’ve already collected and submitted many documents upfront during the preapproval process, you should be set up for success. However, remain flexible and provide any additional documentation required by the lender to secure mortgage financing.


Once you have firm lender approval and you’ve removed conditions on the purchase agreement, don’t change anything about your financial situation until you have the keys. Don’t quit your job, don’t take out a new loan, or don’t make a large withdrawal from your bank account. Put your life into a holding pattern until you take possession of your new home.


So there you have it, six steps to ensuring a smooth home purchase:


  1. Work with an independent mortgage professional.
  2. Put together a mortgage plan.
  3. Figure out what you can actually afford.
  4. Get a pre-approval.
  5. Provide the necessary documentation.
  6. Don’t change anything about your financial situation until you take possession.


If you’d like to discuss your personal financial situation and find the best mortgage product for you, let’s work together. We can figure out a plan to buy a home as stress-free as possible.

If you are buying a home with a suite, keeping your current home as a rental, or already own a rental property, mortgage qualification can get confusing fast. The frustrating part is that you can do everything “right” and still get very different answers depending on which lender you talk to. Here’s a simple breakdown so you understand it and don’t miss out. What are Debt Service Ratios? In Canada, lenders qualify you using two main ratios: Gross Debt Service (GDS) This looks at housing costs only , typically: Mortgage payment Property taxes Heating 50% of strata fees (if applicable) GDS typically needs to be 39% or less of your gross income. Total Debt Service (TDS) This includes everything in GDS , plus other debts like: Car loans Credit cards Lines of credit Student loans TDS typically needs to be 44% or less of your gross income. These ratios are the foundation. If they do not work, the lender will not approve the mortgage, even with strong credit and a solid down payment. How Lenders Treat Rental Income Most people assume lenders look at rental properties based on simple cash flow (rent minus mortgage payment). In reality, most lenders use one of two methods: 1) Addback A percentage of the rental income is added to your gross income for qualification purposes. 2)Offset A percentage of the rental income is subtracted from the mortgage payment tied to the rental property. Different lenders use different percentages and different worksheets. That is why the same borrower can qualify with one lender and fail with another. Benefits of Understanding Lender Methods When you understand how rental income is calculated, you can: Avoid being under-qualified by a lender with conservative rules Get a more accurate picture of your real purchasing power Choose a lender that fits your situation (instead of forcing your situation to fit the lender) Important Considerations A few key points to keep in mind: Rental income is rarely counted at 100% , but some lenders are more generous than others. The method matters just as much as the percentage (addback vs offset). If you own multiple properties, lender worksheets can change the result dramatically. Your lender choice is a strategy decision , not just a rate decision. Real-World Example: Same Clients, Two Very Different Outcomes Here’s an example comparing lenders Scotiabank and Strive, using a fictitious couple: Scenario Household income: $160,000 Existing townhome: $800,000 value with a $525,000 mortgage ( $2,500/month payment) Market rent for the townhome: $3,400/month New purchase: property with a rental suite generating $1,800/month Down payment: 10% Other debts: student loan $165/month , car loan $500/month How Scotiabank viewed it For the townhome rental, they counted half the rent and subtracted the mortgage payment, leaving an $800/month shortfall that gets added into the debt ratios. For the new purchase, 50% of the suite income gets added to income. Max mortgage : $650,700 Max purchase price : $723,000 How Strive viewed it For the townhome rental, Strive used a rental worksheet and calculated $5.20/month of income that can be added to the application. For the new purchase, 100% of the suite income gets added to income, and they did not need to include taxes or heat. Max mortgage : $878,400 Max purchase price : $976,000 The result That’s a $253,000 difference in purchasing power , with the same clients, same income, same debts, and same properties. The difference was lender policy. Quick Summary GDS and TDS ratios are the backbone of mortgage qualification. Rental income is usually counted using Addback or Offset , and each lender handles this differently. Two lenders can produce wildly different results, even with the exact same file. In the example above, lender choice created a $253,000 swing in purchasing power. Next Steps If you are planning to: Buy a home with a suite Keep your current home and convert it to a rental Use rental income to qualify Reach out and I will run the numbers across multiple lenders so you see what you actually qualify for, not just what one lender will allow.

Gross Debt Service (GDS) : The ratio that measures housing costs as a percentage of gross income. Offset : A method where a lender subtracts a percentage of rental income from the rental property’s mortgage payment for qualification. Total Debt Service (TDS) : The ratio that measures housing costs plus other debts as a percentage of gross income.
