How do lenders assess my ability to manage mortgage payments?

Lenders evaluate your ability to manage payments using Gross Debt Service (GDS) and Total Debt Service (TDS) ratios.

Key Points

  • Lenders look at your income and debts to see if you can afford your mortgage payments.

  • These calculations include a buffer to make sure you can handle higher interest rates or unexpected expenses.

  • To qualify for a mortgage, you need to prove you can afford your payments at your actual interest rate plus a buffer, or a set minimum rate.

  • This rate is reviewed regularly to make sure it's still a good measure of affordability.

  • Your mortgage payment, income, heating costs, property taxes, condo fees, and other debts all factor into whether you qualify for a mortgage.
