Rent guarantee insurance (also known as rental income insurance) is a type of policy specifically designed to protect landlords in the event that their tenants do not pay rent. This coverage can replace lost rental income and cover legal fees associated with evicting non-paying tenants. It can also provide protection if renters damage the property or violate other aspects of their rental agreement. Rent guarantee insurance is typically offered as an add-on to a standard commercial landlord insurance policy, but it can also be purchased separately from some insurers.
