Why calculate mortgage affordability?

When you're looking to buy a home, it's handy to know how much you can afford. Being able to calculate an estimate of how much you're able to borrow is an important part of setting your budget.

“How much house can I afford?” is a common question when starting the property hunt; you also need to determine if you have enough cash resources to purchase a home. The cash required is derived from the down payment put towards the purchase price, as well as the closing costs that must be incurred to complete the purchase. We can help you estimate these closing costs with the Cash Needed tab under the mortgage affordability calculator above.

Taken together, understanding how large a mortgage you can afford to borrow and the cash requirements involved will help you determine what kind of home you should be searching for. 

 

February 2024 Canadian mortgage affordability update

Finally, some relief for Canadian home buyers! According to the latest home affordability data released by Ratehub.ca, borrowing conditions improved across Canada in January, due to a mix of lower mortgage rates, and softening prices in most markets.

The report illustrates how changing mortgage and stress test rates, combined with real estate prices, impact the minimum income required to qualify for a mortgage in each market.

According to the findings, home prices decreased in seven of the 13 markets studied. Meanwhile, the mortgage stress test also declined to an average of 7.71%, compared to 8.16% in December.

The largest improvement was seen in Vancouver, where the average home price declined by $7,400 to $1,161,300, resulting in $9,620 less income required to purchase a home.

Toronto ranked third in terms of improved affordability, as the average home priced dipped by $1,400 to $1,065,800. As a result, a borrower looking to buy a home there requires $7,800 less in income than they would have in December.

What is mortgage affordability?

Mortgage affordability refers to how much you’re able to borrow based on your current income, debt and living expenses. It’s essentially your purchasing power when buying a home. The higher your mortgage affordability, the more expensive a home you can afford to purchase.

The term ‘affordability’ is also used to describe overall housing affordability, which has more to do with the cost of living in a particular city. If the cost of housing relative to the average income in a city is high, it will be seen as a less affordable place to live. The two terms are related, but it’s important to understand the difference.

There are many factors that will affect the maximum mortgage you can afford to borrow, including the household income of the applicants purchasing the home, the personal monthly expenses of those applicants (car payments, credit expenses, etc.) and the expenses associated with owning a home (property taxes, condo fees and heating costs, etc.).

 

How much can I afford?

How much you can afford to spend on a home in Canada is primarily determined by how much you can borrow from a mortgage provider. That is, unless you have enough cash to purchase a property outright, which is unlikely. Use the mortgage affordability calculator above to figure out how much you can afford to borrow based on your current situation.

 

How to use the mortgage affordability calculator

To use our mortgage affordability calculator, simply enter your and your co-applicant’s income (if applicable), as well as your living costs and debt payments. The calculator can estimate your living expenses if you don’t know them.

With these numbers, you’ll be able to calculate how much you can afford to borrow. You can also change your amortization period and mortgage rate to see how that would affect your mortgage affordability and your monthly payments.

How to estimate affordability

There is a rule of thumb about how much you can afford, based on the calculations your mortgage provider will make. Your lender will use two debt ratios when determining whether you can afford a mortgage. These ratios are called the Gross Debt Service (GDS) ratio and Total Debt Service (TDS) ratio. They take into account your income, monthly housing costs and overall debt load.

The first affordability guideline, as set out by the Canada Mortgage and Housing Corporation (CMHC), is that your monthly housing costs – mortgage principal and interest, taxes and heating expenses (P.I.T.H.) - should not preferably not exceed 32% of your gross household monthly income, up to a maximum of 39%.  For condominiums, P.I.T.H. also includes half of your monthly condominium fees.

The second requires that your total debt load (which includes housing costs), totals no more than between 40% - 44% of your gross household income. In addition to housing costs, your total monthly debt load would include credit card interest, car payments and other loan expenses. The sum of your total monthly debt load as a percentage of your gross household income is your TDS ratio.

 

 

Maximum limits

While the general preferred guidelines for GDS and TDS are 32% and 40% respectively, most borrowers with good credit and steady income are allowed to qualify at the upper end of the debt-ratio thresholds.

The maximum GDS limit used by most lenders to qualify borrowers is 39% and the maximum TDS limit is 44%. Our mortgage calculator uses these maximum limits to estimate affordability.

On July 1st, 2020, the CMHC implemented new GDS and TDS limits for mortgages that it insured, with the new GDS limit for CMHC-insured mortgages becoming 35% and the new TDS limit for CMHC-insured mortgages becoming 42%. However, on July 5, 2021, these updated requirements for insured mortgages were reversed, and the GDS and TDS limits reverted to 39% and 44%, respectively. 

The CMHC changes had fairly minimal impact on borrowers, as Sagen and Canada Guaranty, the two other mortgage insurance providers in Canada, did not change their maximum limits. Consequently, mortgage lenders continued to use the old maximum GDS/TDS limits of 39/44 available through these other insurers. The main result of CMHC's temporary change in requirements was a major loss in market share, which is why the more stringent requirements were reversed in June 2021. 

 

Down payment

Your down payment is a benchmark used to determine your maximum affordability. Ignoring income and debt levels, you can determine how much you can afford to spend using a simple calculation.

If your down payment is $25,000 or less, you can find your maximum purchase price using this formula:

   Down Payment

÷ 5%

= Maximum Affordability

If your down payment is $25,001 or more, you can find your maximum purchase price using this formula:

  (Down Payment Amount - $25,000)

÷ 10%

+ $500,000

= Maximum Affordability

For example, let's say you have saved $50,000 for your down payment. The maximum home price you could afford would be:

  ($50,000 - $25,000)

÷ 10%

+ $500,000

= $750,000

Any mortgage with less than a 20% down payment is known as a high-ratio mortgage, and requires you to purchase mortgage default insurance, often referred to as CMHC insurance (though, as noted above, mortgage default insurance is also provided by Sagen and Canada Guaranty).

 

Cash requirement

In addition to your down payment and mortgage default insurance, you should set aside 1.5% - 4% of your home's selling price to cover closing costs, which are payable on closing day. Many home buyers forget to account for closing costs in their cash requirements.

 

Other mortgage qualification factors

In addition to your debt service ratios, down payment and cash for closing costs, mortgage lenders will also consider your credit history and your income when qualifying you for a mortgage. All of these factors are equally important. For example, even if you have good credit, a sizeable down payment and no debts, but an unstable income, you might have difficulty getting approved for a mortgage.

Keep in mind that the mortgage affordability calculator can only provide an estimate of how much you'll be approved for, and assumes you’re an ideal candidate for a mortgage. To get the most accurate picture of what you qualify for, speak to a mortgage broker about getting a mortgage pre-approval.

 

How to increase your mortgage affordability

If you want to increase how much you can borrow, thus increasing how much you can afford to spend on a home, there are few steps you can take.

1. Save a larger down payment: The larger your down payment, the less interest you’ll be charged over the life of your loan. A larger down payment also saves you money on the cost of mortgage default insurance

2. Get a better mortgage rate: Shop around for the best mortgage rate you can find, and consider using a mortgage broker to negotiate on your behalf. A lower mortgage rate will result in lower monthly payments, increasing how much you can afford. It will also save you thousands of dollars over the life of your mortgage.

3. Increase your amortization periodThe longer you take to pay off your loan, the lower your monthly payments will be, making your mortgage more affordable. However, this will result in you paying more interest over time.

These are just a few ways you can increase the amount you can afford to spend on a home, by increasing your mortgage affordability. However, the best advice will be personal to you.
