Which of the following best characterizes a non-disturbance clause?

A non-disturbance clause is primarily designed to provide stability and security for tenants during various property transitions, such as when the property is sold or if the landlord defaults on their mortgage. This clause ensures that the tenant's lease rights remain intact, preventing them from being evicted or disturbed in their tenancy even in the event of foreclosure or changes in ownership. It is particularly important for tenants to protect their interests, ensuring that their right to occupy the premises is upheld irrespective of any changes affecting the landlord.

The essence of a non-disturbance clause is its function to promote tenant stability, which is why the characterization provided in the answer is the most accurate. This provision fosters a sense of security for tenants, making them more willing to enter into long-term lease agreements, ultimately benefiting both parties involved.
