Which type of occupancy occurs when a tenant is allowed to stay in a property with the landlord's consent?

The type of occupancy that occurs when a tenant is allowed to stay in a property with the landlord's consent is known as an estate at will. This arrangement allows tenants to occupy the property under an informal agreement, where either party can terminate the tenancy with proper notice. It typically does not have a fixed duration, providing flexibility for both the landlord and the tenant.

In contrast, an estate at sufferance refers to a situation where a tenant remains in the property after their lease has expired without the landlord's permission, creating a potential conflict. A fixed-term lease involves a specific duration agreed upon by both tenant and landlord, and remains in effect until the designated end date is reached. An automatic renewal lease allows a lease to continue under the same terms without the need for a new agreement unless one party provides notice to terminate. Thus, the key aspect that distinguishes an estate at will is the mutual agreement for occupancy, making it the correct choice in this scenario.
