How this is calculated
- Rent is reduced by the vacancy allowance, then operating costs (property tax, insurance, condo fees, maintenance, management, utilities) are deducted.
- Land transfer tax uses Ontario rates; Toronto adds a municipal tax that is not included here.
- Lenders may count only part of the rental income when qualifying you. Figures are before income tax and are estimates only.

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.
