Unless you are describing a buy-out clause in your lease, your landlord is going to have to make a diligent effort to find a new tenant for the remainder of your lease term and, if she does, your damages for unpaid rent would be limited to the period during which the unit was unoccupied (plus, if rent rates have dropped in your area, the difference between what you paid and what the new tenant pays for the duration of the lease).

"Probably" doesn't mean "Yes".
