Practical Example
Consider a four-unit rental property.
Property Information
- Monthly Rent per Unit = $1,800
- Number of Units = 4
- Occupancy Rate = 95%
- Additional Monthly Income = $200
Monthly Rental Revenue
$1,800 × 4 = $7,200
Occupancy Adjustment
$7,200 × 95% = $6,840
Add Additional Income
$6,840 + $200 = $7,040
Annual Rental Income
$7,040 × 12 = $84,480
Estimated Annual Rental Income = $84,480
