Most people use the word “lease” to describe a written rental agreement that is for a set period of time, such as a year, with a fixed amount of rent. But some leases permit an increase of rent after a 30-day notice. The lease will state how the tenant and landlord can end the lease early.
If you have a lease with a fixed amount of rent, the landlord cannot raise the rent during the fixed term. However, with this type of lease, if you end the lease early you may have to either continue to pay rent until the landlord rents to another tenant or pay a lease break fee, if such a fee is described in your written rental agreement. Whenever a tenant terminates a lease early, the landlord has an obligation to try to rent the unit to someone else; this is known as the obligation to “mitigate damages.”
