An asking rent is a starting observation
Compare properties with similar location, size, condition, services and tenancy terms. Record whether a figure is an advertised rent, an occupied-unit survey average or a newly signed lease. They answer different questions. Market-wide rental easing does not determine the rent for a particular building, and a provincial rent-increase rule does not establish the market rent on a new tenancy.
Use three separate views of the property
Net operating income describes the property before financing and income tax. Cash flow includes money actually paid for financing and operations. Taxable rental income follows tax rules and can differ from cash flow. Mortgage principal reduces cash but is not the same thing as a deductible interest expense. Keep an operating worksheet, a financing worksheet and a tax worksheet rather than calling all three profit.
Test the weak year before the strong year
Use a second scenario with lower collected rent, a vacancy period, a repair bill and a higher renewal cost. For a short-term rental, add cleaning, platform costs, seasonality and local permission checks. For a renovation-and-refinance strategy, test a lower appraised value and delayed completion. Refinancing proceeds are borrowing, not operating income; a refinancing plan can fail even if the property’s rent covers some expenses.
Plan the exit while keeping records
Retain purchase, improvement, financing and disposition records. Before selling or changing use, review capital gains, any capital cost allowance history and reporting with a qualified tax adviser. A cap rate is not a promised annual investor return. A sale-tax estimate and the mortgage payout both affect cash available at exit. Avoid counting a favourable future sale price as the reserve for repairs today.
Put the explanation to work
Use your own dated inputs. Save a base case, change the assumption that matters, and compare the cash available and obligations in each case.
