An offer to purchase real estate is terminated by all of the following EXCEPT:

Death of the offeror terminates the offer because the offeror cannot perform their contractual obligations after death. Most states require estate representatives to be appointed before any real estate contracts can be enforced.

A counteroffer terminates the original offer because it rejects the original terms and proposes new ones. This creates a new offer that the original offeror can accept or reject.

Rejection by the offeree terminates the offer because it definitively communicates the offeree's unwillingness to accept the original terms. Once rejected, the offer cannot be revived unless the offeror renews it.
