One of the most important reasons landlords hire a property manager is to help limit exposure to and manage the inherent risk of owning rental property. The rental dwelling insurance make sure you as a property owner and your property manager are both covered in any risks related to the property.
It is vital to add your property manager as "additional insured, "not just as "additional interest." This is to make sure your property manager is properly covered, meaning the homeowner's policy coverage is extended not only to the owner but also to the listed agent or management company. Additional interest will not extend the coverage, and it will simply notify the property manager about policy renewal.
