NOI = Income minus Operating Expenses; mortgage payments and capital expenditures are not deducted from NOI. Cash Flow = Income minus Total Expenses.

Value growth and loan paydown are measured at each year-end.

Estimates depend on the assumptions entered. Actual rents, expenses, vacancy, financing, and property values may differ. This model assumes a fully rented, stabilized property from Year 1 with cash financing or a fixed-rate, fully amortizing loan. It does not model renovation downtime, refinancing, depreciation, income taxes, or transaction-specific tax consequences. Maintenance and capital expenditure allowances are separate; avoid counting the same costs twice.
