Find the right balance.

Now is the time to make an assessment of your overall financial picture to ensure that you balance your home purchase with all of your personal and lifestyle goals. This includes any debts you or any co-borrowers might have, your credit score and your ability to keep up with new home ownership expenses.

To get you started, below are two simple calculations that most lenders use as a guide for housing costs and overall debt levels. Keep in mind that these numbers are prescribed maximums and that you should strive for lower ratios for a more affordable lifestyle.


Gross Debt Service (GDS) ratio

The GDS looks at your proposed new housing costs (mortgage payments, taxes, heating costs, and 50% of condominium fees, if applicable) in relation to your income. Generally speaking, this amount should be no more than 32% of your gross monthly income.

Total Debt Service (TDS) ratio

The TDS ratio measures your total debt obligations (including housing costs, loans, lines of credit, car payments, and credit card bills) in relation to your income. Generally speaking, your TDS ratio should be no more than 40% of your gross monthly income.


Once you know what you can afford, get a pre-approval.

A pre-approval1 will help you determine the maximum amount of money that you may be able to borrow for your first home, which can make it easier to narrow your search and find a home that fits your budget. We are committing to a specific term and interest rate for the pre-approval.

Make an appointment with a TD Mortgage Specialist to discuss a mortgage pre-approval.

There are several advantages to taking this step early.

  • You'll know how much you can afford
  • You'll know what your interest rate will be (guaranteed to 90 days)
  • You'll be in a good position to make an offer when you find the right home
  • There's no obligation or cost to you
