The decision of whether or not to accept a purchase offer is entirely up to the seller. However, when property is listed for sale with a real estate agent, the seller is “offering to sell” at the terms set forth in the listing. Therefore, if a prospective buyer offers to purchase the property under the exact same terms as set forth in the listing, the seller must accept the offer. However, if the buyer’s offer differs in any way from the listing (such as including any contingencies or conditions), the seller is free to reject the offer.
