Suppose you are considering a rental property with the following details:
Property Information
- Purchase Price = $250,000
- Down Payment = $50,000
- Monthly Rent = $2,000
Annual Rental Income
$2,000 × 12 = $24,000
Annual Expenses
- Property Taxes = $3,000
- Insurance = $1,200
- Maintenance = $1,800
- Management Fees = $1,500
Total Expenses = $7,500
Annual Profit
$24,000 − $7,500 = $16,500
ROI Calculation
ROI = ($16,500 ÷ $50,000) × 100
ROI = 33%
The investment generates an estimated ROI of 33%.
