Mortgage qualifier

What this is

How big a mortgage can you actually qualify for in Canada?

Lenders cap you on two ratios: GDS (Gross Debt Service, housing-only) at 39%, and TDS (Total Debt Service, all monthly debt) at 44%. Both are gross-income measures. Whichever ratio binds first sets your ceiling.

·GDS = (mortgage + property tax + heating + half condo) ÷ gross monthly income
·TDS = GDS items + car payments + credit-card minimums + loans + child support
·Stress test: Canadian banks qualify you at the higher of contract+2% or 5.25%.
