Give every cost a clear home
An operating budget should show what it costs to run the property during the chosen period. Typical categories to investigate include property taxes, utilities, staffing, insurance, repairs, cleaning, security, software, marketing and administration. Define the reporting boundary before collecting numbers. Is owner labour included? Is a shared management cost allocated to this property? Are amounts before recoverable sales taxes? A budget becomes difficult to compare when these decisions are left implicit. Use a documented policy and apply it consistently across alternatives and scenarios.
Separate fixed commitments from activity
Some expenses continue even when the facility is empty; others change with customers or workload. Classify costs by their actual contract or operating behaviour rather than by a generic percentage of revenue. A software subscription may include a fixed charge plus a per-unit component. Staff time may change in steps rather than smoothly with occupancy. Ask what the minimum viable operation requires before the first tenant arrives. A model that reduces every expense to zero at zero occupancy can dramatically understate the cash required during opening.
Keep NOI separate from cash flow
Net operating income is effective operating income less the defined property operating expenses. Debt principal and interest are excluded from NOI in this model, as are depreciation, income tax and capital expenditure. Cash flow after debt service then deducts the loan payment; further capital spending and taxes require separate lines. For an illustrative month with C$12,000 effective income and C$7,000 operating expenses, NOI is C$5,000. A C$5,500 loan payment creates a C$500 shortfall before other cash items. Positive NOI alone therefore does not demonstrate positive owner cash flow.
Plan for maintenance and replacement
Routine servicing and eventual replacement should both be visible without double counting. A service contract may belong in recurring expenses, while replacing a major system may be capital expenditure. Set out the assumed dates and amounts for larger renewals, then ask a qualified supplier to review them. A cash reserve is a funding allocation; it is not automatically an expense or a substitute for the future payment. Record how the model treats reserves and compare alternatives on the same basis. Condition assessments are especially important when evaluating an existing property.
Reforecast with evidence
Build the first budget from quotes, assessed obligations and explicit workload assumptions. After opening, compare actual amounts with the budget and explain the differences. Separate a one-time incident from a recurring change, and preserve both in the history. Stress-test higher utilities, a property-tax change and an unexpected repair while keeping revenue assumptions visible. Review GST/HST treatment independently; collected tax is not simply extra rental income. The Lab's expense fields are educational inputs, so replace the defaults with project-specific evidence and a consistent accounting policy before relying on a forecast.
