How much should i pay my property tax on my condo ? If my unit is vacant and will be vacant at least for the next 12-18months? Do you think IRAS will allow me to do a property refund?

As a clause in the letter "if a property is vacant for at least 30days or a calender month, you may apply for refund for a vacant period if the property is intended for letting and no tenant could be found despite reasonable efforts to do so or the property is undergoing repairs to make it fit for occupation"

If i could not find a suitable contractors for works it's obviously non-livable.........think they'll let me refund? Thks.
