An Overview of the Home Buying Process

Tim Lyon • November 23, 2023

If you’re in the early stages of planning to buy either your first home or your next home, you’ve come to the right place! Even if you’ve been through it before, the home buying process can be daunting, but it doesn’t have to be when you have the right people on your side!

 

The purpose of this article is to share a high-level view of the home buying process. Obviously, the finer details can be addressed once you’ve submitted an application for pre-approval. But for now, here are some of the answers to general questions you may have as you work through your early preparations.

 

Are you credit-worthy?

 

Having an established credit profile is essential when applying for a mortgage. For your credit to be considered established, you’ll want to have a minimum of two trade lines (credit cards, loans, or lines of credit) with a minimum limit of $2500, reporting for a period of at least two years.

 

From there, you’ll want to make sure that your debt repayment is as close to flawless as possible. Think of it this way: Why would a lender want to lend you money if you don’t have a history of timely repayment on the loans you already have? Making your payments on time, as agreed, is crucial.

 

We all know, however, that mistakes can happen and payments might get missed. If that's the case, it’s best to catch up as quickly as possible! Late payments only register on your credit report if you're past due by 30 days.

 

How will you make your mortgage payments?

 

When providing you with a mortgage, lenders are trusting you with a lot of money. They'll want to feel really good about your ability to pay that money back, over an agreed period of time, with interest.

 

The more stable your employment, the better chances you have of securing mortgage financing. Typically, you’ll want to be employed in a permanent position or have your income averaged over a period of two years. If you’re self-employed, expect to provide a lot more documentation to substantiate your income.

 

How much skin do you have in the game?

 

If you're borrowing money to buy a home, you’re going to have to bring some money to the table. The best down payment comes from accumulating your own funds supported by documents proving a 90-day history in your bank account. Other down payment sources, such as a gift from a family member or proceeds from another property sale, are completely acceptable.

 

In Canada, 5% down is the minimum requirement. However, depending on the purchase price, it might be more. Also, you need to be aware that you will likely have to prove access to at least 1.5% of the purchase price to be allocated for closing costs.

 

How much can you afford?

 

Here’s the thing. What you can afford on paper and what you can afford in real life are often very different amounts. Just because you feel you can afford the proposed mortgage payments, know that you will have to substantiate everything through documentation.

 

The amount you actually qualify to borrow is based on many factors, certainly too many to list in an article designed to provide you with an overview of the home buying process. However, with that said, it’s never too early in the home buying process to seek professional advice. Our services come at no cost to you; it would be our pleasure to help.

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.
