Exemple Résolu
A rental property earns $72,000 gross rent plus $3,600 other income, with 7% vacancy and $20,640 total expenses.
- Gross potential income: $72,000 + $3,600 = $75,600
- Vacancy loss: $75,600 x 7% = $5,292
- Effective gross income: $75,600 - $5,292 = $70,308
- Total expenses: $6,000 + $2,400 + $4,800 + $5,040 + $2,400 = $20,640
- NOI: $70,308 - $20,640 = $49,668
- Expense ratio: $20,640 / $70,308 = 29.4%
