How to determine the annual value of a property that is rented (let-out) for part of the year and self-occupied for the rest of the year?

The Expected Rent (i.e. generally the fair rent or standard rent for such property) for the entire year must be taken into account when calculating the GAV for a property that is partially self-occupied and partially rented out. 

A comparison between this Expected Rent (ER) for the entire year and the Actual Rent (AR) for the period during which such property was rented out. The higher amount of ER and AR will be considered as Gross Annual Value (GAV) of the property. Municipal taxes are to be deducted from GAV for the entire year to calculate the Net Annual Value (NAV).​
