Ans. Where the property or any part of the property is let and was vacant during the whole or any part of the previous year and owing to such vacancy the actual rent received or receivable by the owner in respect thereof is less than the reasonable expected rent than the actual rent so received or receivable (as reduced by the vacant allowance) shall be considered to be the Gross Annual Value of the property.
