Debt ratios are financial calculations lenders use to determine how much of your income goes toward debt payments, with the two main types being Gross Debt Service (GDS) and Total Debt Service (TDS) ratios. For Canadian real estate investors, these ratios are critical qualifying factors that determine borrowing capacity, with most lenders requiring GDS below 39% and TDS below 44%, though rental income from investment properties can help offset these calculations.
