How do GDS and TDS ratios impact debt consolidation approvals?

Gross Debt Service (GDS) and Total Debt Service (TDS) ratios are crucial for lenders to assess a borrower's debt management ability.

Key Points

  • Your Gross Debt Service (GDS) ratio looks at your mortgage payment (principal and interest), property taxes, heating, and condo fees.

  • Your Total Debt Service (TDS) ratio includes everything in your GDS, plus all your other debt payments like credit cards and loans.

  • Lenders will check that you can still afford your payments if interest rates go up or your financial situation changes.

  • If you have a mortgage with less than a 20% down payment, the mortgage insurer has rules about how much debt you can carry.

  • Even if you have a larger down payment, lenders will still carefully assess your ability to repay your mortgage based on current and future economic conditions.
