cancelling ND lease

hey, i was wondering how likely id be able to cancel a ND lease?

i was offered a lease and want to sign it, but my roommate hasn’t received one yet and i’m not sure if she will before my deadline. so i want to sign my lease just in case, but in the case she isn’t able to get a lease, we’d probably be looking at off-campus apartments. and id want to cancel my ND lease in that case.
