The Mortgage Interest amount in Box 1 is calculated as follows:
Current Interest Paid * ((Unit Shares * Number of Days Lease Occupied) / Weight Factor)

The Real Estate Tax amount in Box 10 for 2016 and 2018 or Box 11 for 2017 is calculated as follows:
Tax Amount * ((Unit Shares * Number of Days Lease Occupied) / Weight Factor)

Explanation of values:

Unit Shares are entered for the unit (Setup, Units). You may want to enter a value that is less than the actual number of unit shares if multiple leases occupy the same unit during the same time period.
Number of Days the Lease was Occupied is calculated by using the actual move-in and move-out dates on the lease. For the reporting year, if the move-in date is after the calendar year ends or if the move-out date is before the calendar year begins, the lease will not process. Otherwise, the days occupied in the reporting year are counted. The unit is not considered occupied on the move-out date.
Weight Factor calculates (Unit Shares * Number of Days the Lease was Occupied) for each unit and sums that figure for all units on a property.
For example: ((Unit_1 Shares * Total Days Unit_1 Occupied) + (Unit_2 Shares * Total Days Unit_2 Occupied) + .......... + (Last_Unit Shares * Total Days Last_Unit Occupied))

Note: The "total days the unit was occupied" is the number of days each unit was occupied in the reporting year. This figure needs to include all other leases that occupied this unit for the reporting year.
