Let's say two years into a 5-year lease term and you get a new job that requires you to move to a different city. What do you do? Your only options are to either (i) get your landlord to agree to let you out of the lease early (which could be costly), (ii) find someone to take over the balance of the lease through an assignment, or (iii) subletting to another tenant who will rent the place for the balance of the lease term, which means you remain on the lease as the original tenant.
