An Eviction Notice Letter to a Tenant is an official letter from a landlord or property management company notifying a tenant that they have violated the terms of their lease agreement and must vacate the property within a certain period of time. The notice typically lists the reasons for eviction, any damages that need to be paid by the tenant and a timeline for them to move out. It also serves as a final warning before taking legal action against the tenant if they fail to comply with the terms stipulated in the notice.
