How it is calculated
- The purchase loan is the price minus your down payment. Renovation and closing costs are paid in cash (no construction loan).
- Mortgage payments use the Canadian convention: fixed rate compounded semi-annually, paid monthly.
- Net operating income (NOI) = (total monthly rent − monthly operating costs) × 12. Value at completion = NOI ÷ cap rate.
- The refinance loan = value × LTV, at the same rate and amortization. Cash out = new loan − original loan (principal paid down during construction and refinance fees are ignored).
- Vacancy, taxes on income, inflation and rent growth are not modelled. Include a vacancy allowance in operating costs.
