Before you take out landlord insurance you’ll need to know the rebuild cost of your investment property. Our House Rebuild Calculator uses information from the Society of Chartered Surveyors in Ireland to calculate the rebuild cost of a property. If the rental property is in an apartment building, the building insurance should be covered by the annual management fees. However, always ask for a copy of the policy document to see if it is adequate. It might be necessary to take out additional coverage for contents.
