There are no repercussions to be outlined. As far as the landlord is concerned, you agreed to pay $X a month through the end of the lease. In exchange, you get to live in the property and you are responsible for any excess damage. If you choose to live someplace else, that’s not anything the landlord cares about as long as he gets paid.

Now, if you are leaving because the landlord didn’t hold up his responsibilities (maintenance and repairs, etc) you might be allowed to walk away from the lease. But you will have to prove that things were really bad for it to get to that point.
