How this is calculated

  • Whether you can extend your amortization at renewal depends on your lender's policy and on how you qualify.
  • Estimate only. It assumes the same balance and remaining amortization, and semi-annual compounding as in Canadian fixed-rate mortgages.

But how does this apply to your business income?

This calculator estimates the numbers you entered. How a lender treats your salary, dividends or business income is a separate question, and it's the one the Mortgage Readiness Review looks at first.
