Owner-Occupier Decision Tool

Lease or buy?
Expose the assumptions.

Compare two premises that support the same business requirement. See cash outflow, debt remaining and modelled retained equity without a manufactured recommendation.

Undiscounted cash-flow model. It excludes GST/HST, income tax, CCA, opportunity cost, financing fees not entered, refinancing, variable rates, unexpected capital, business downtime and transaction-specific adjustments. Property value growth is your assumption, not a Commercially forecast. Negative net sale equity represents an estimated shortfall.

How the model works

One horizon.
Two capital strategies.

Lease scenario. Rentable area is multiplied by base and additional rent. The entered growth rate is applied annually, then one-time fit-up and moving costs are added.

Ownership scenario. The model adds down payment, acquisition costs, mortgage payments and escalating ownership costs, then subtracts estimated sale equity after selling costs and debt.

Undiscounted comparison. Cash flows are not discounted to present value and capital has no assumed opportunity cost. Use the result to identify assumptions for a broker, lender, accountant and counsel—not to select a property.
