Brampton (Asking price x 1.2% divided by 12)
Mississauga (Asking price x 0.98% divided by 12)
Toronto (Asking price x 0.75% divided by 12)
 * Monthly heating costs
If unknown. Enter $100.00 which is the industry standard.
  1/2 the monthly condo fee
Condo fees can vary greatly from one building to another due to varying ammenities and services which are included in the fee. If known. Divide the monthly condo fee in half and enter the value. If unknown. Multiple the square footage of the unit by $0.25 and use that value. 		(If applicable)
  Other monthly payments
Add up all of your regular monthly payments due on debt obligations such as car loans/leases, student debt, credit cards, personal loans etc and enter in the value. (Tip: For credit cards use 3% of the total amount outstanding on all cards).

Understanding GDS & TDS ratio's

Most lenders use two primary calculations to determine if you fall within their lending guidelines when applying for a mortgage. Gross debt service ratio, and total debt service ratio.

Gross debt service ratio (GDS) represents the percentage of the borrower's income required to cover payments for housing related costs. These costs include mortgage payments (principal & interest), property taxes, heating costs, and half of the monthly condo fee (If applicable).

Total debt service ratio (TDS) represents the percentage of a borrower's income required to service both housing related costs (GDS), and all other debt obligations such as car loans, student loans, credit cards, personal loans etc etc.

In general. Lenders will provide mortgage funds as long as the borrower's GDS ratio is not more than 35% and their TDS ratio is not more than 42%.

But the Canada Mortgage & Housing Corporaton (CMHC) will insure mortgages up to 39% GDS. So if a borrower has a good credit history and a 680 plus credit score. A lender might be willing to bump the max GDS % ratio up to 39% and provide the necessary mortgage funds.

With the mortgage marketplace being extremely competitive. Ultimately, there are no hard & fast rules. If you're getting ready to buy a home, and would like some assistance on getting approved for a mortgage? (Traditional or non-traditional).
