Analyze rental-property income, expenses, and vacancy
Compare properties only after rent, vacancy, operating costs, capital work, financing, and owner transfers are classified consistently. Start with the what one row represents and definitions, calculate only from eligible records, and check the result against the source before using it.
Where errors enter the process
Rent rolls show charges while the bank shows cash, maintenance invoices mix repairs and capital improvements, and owner transfers look like income or expense. Comparing raw net cash can reward a property merely because a large bill has not posted yet.
A method you can follow
- Define the decision: Reconcile rent due, concessions, arrears, and cash received by unit and month.
- Prepare the evidence: Classify operating, capital, financing, deposit, and owner transactions separately.
- Calculate the result: Calculate occupancy, collected rent, operating margin, and cash flow using consistent definitions.
- Review the exceptions: Review one-time works, delinquency, and upcoming lease events before comparing properties.

Decide how much review the task needs
| Approach | What it answers | What remains at risk |
|---|---|---|
| Quick spreadsheet total | A narrow descriptive question | Definitions, duplicate rows, timing, and exceptions may be hidden |
| Reviewed analysis | The stated decision with reconciled evidence | Human judgment is still required for policy and action |
| Ongoing monitored workflow | The same decision across new periods | unexpected column changes and changed business rules still need review |
