If any new ownership decides to break the lease, I'm sure the county would make it anything but easy or cheap for them to do so. If for no other reason than it would be political suicide for any county politician to roll over and play dead on this issue.
As to the bolded, this is a very good example. But say you are this person, you would certainly pay a penalty for breaking the lease. But after paying the penalty, where would you be living , in the original apartment or someplace else? That is, do you think the court would force you to stay in the original apartment?
