What is the primary risk associated with a tenancy at sufferance?

In a tenancy at sufferance, the primary risk arises from the tenant's unlawful occupancy of the property after the lease has expired. This situation typically occurs when a tenant remains in the rental unit without the landlord's permission, having outlasted their lease period.

The reason eviction can occur at any time without notice is due to the tenant's legal status. Since they do not have a valid lease, landlords are empowered to act swiftly to reclaim their property. The absence of a formal lease agreement means that the tenant lacks the legal protections that come with a rental contract, making them vulnerable to immediate eviction proceedings at the landlord's discretion.

The other options highlight conditions that do not accurately convey the nature of a tenancy at sufferance. The tenant is not required to extend the lease, nor do they have any inherent rights to ownership or significant control over the rental rate during this period. In fact, the tenant’s position is quite precarious as they are technically trespassing.
