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.
