First check what type of policy you have. Most rentals (single family to 4 units) are covered under a dwelling policy form.
With a Dwelling Fire 1 policy, vandalism is not typically covered. This type of policy typically provides coverage for damages to the physical structure of the rental property from perils such as fire, lightning, windstorms, and hail, but not from intentional acts like vandalism.
If coverage for vandalism is desired, it may be possible to add an endorsement or a separate policy for this type of coverage.
However most Dwelling Fire 3 policies do cover vandalism.
Make sure to check on more than the price when searching for insurance. Items like vandalism are not listed on the declaration page and are instead buried in the lengthy policy document.
It is important to carefully review the policy details and speak with an insurance agent to understand the coverage provided.
