Final answer:
The important seller responsibility documented in the listing agreement is marketing the property.
Step-by-step explanation:
The important seller responsibility that is documented in the listing agreement is a) Marketing the Property. This means that the seller is responsible for promoting the property and finding potential buyers through various marketing methods, like advertising, open houses, and online listings.
While setting the listing price (option b) is a crucial step in the selling process, it is not specifically documented in the listing agreement. The listing agreement usually covers the terms and conditions of the agreement between the seller and the real estate agent.
Providing property disclosures (option c) is another important seller responsibility, as it involves revealing any known defects or issues with the property to potential buyers. This helps buyers make an informed decision before purchasing the property.
Paying agent's commission (option d) is typically the responsibility of the seller, but it may not always be explicitly documented in the listing agreement. The commission is usually included as part of the agreement between the seller and the real estate agent.
