What requirement must be included in a residential lease?

In a residential lease, the inclusion of terms regarding rental payment and duration is crucial as it delineates the financial obligations of the tenant and defines the length of time for which the lease is valid. These terms establish a clear understanding between the landlord and the tenant, ensuring both parties are aware of when payments are due and how long the tenant has the right to occupy the property. This clarity helps to prevent disputes over payments and occupancy duration, which could lead to legal complications if not specified.

The other options either lack practicality or are unrealistic. For example, permitting unrestricted modifications would typically not be acceptable to landlords, as it allows tenants to alter the property without permission, potentially harming its value. A guarantee of property appreciation is also not something that can realistically be included in a lease, as it depends on factors outside the control of either party. Lastly, relying solely on verbal agreements might lead to misunderstandings and conflicts, as oral agreements can be difficult to enforce in a legal context compared to a written lease that documents all terms clearly. Thus, having the terms of rental payment and duration in writing is fundamental to any residential lease.
