If you are a Temporary Resident looking to move into the property you are buying, then FIRB approval is generally just a technicality. MAP will guide you through the process but essentially its is just an extra form you need to complete and send in to the FIRB.
If you are not looking to live in the property and therefore buy it as an investment, FIRB approval is more difficult. As a general rule, FIRB approval for such purchases will only be granted if the property is brand new, to be built (ie, vacant land) or has been only just built within the past year.
