Is there any laws on what a landlord can collect when breaking 12 month lease

The landlord will incur damages, in the form of lost rent for the two remaining months of the lease, damages (greater than security deposit), and the cost incurred to re-rent the rental space. However, the landlord owes a duty to mitigate her damages. This means the landlord must make a reasonable effort to find a new tenant and Not leave you on the hook for the remaining two months. As a real estate attorney, my approach would be to send notification of your intent to vacate, simultaneously notifying the landlord of her duty to mitigate.
