Final answer:
The statement regarding the retention of accepted offers for six years and unsuccessful offers for one year by the listing brokerage is true. This practice is important for legal, audit, and regulatory purposes in the real estate industry.
Step-by-step explanation:
The statement regarding the retention period of offers by the listing brokerage in real estate transactions is true. Accepted offers must be retained for a minimum of six years by the listing brokerage as they are legally binding agreements and may be subject to various regulatory requirements and audits. On the other hand, unsuccessful offers need to be retained for at least one year, and the brokerage can choose to keep either the summary document or a full copy of the offer. These retention periods are important for record-keeping, potential disputes, and following the regulations set forth in the real estate industry.
