Do I need a written agreement to show property without representation?It depends. If you are showing residential property for sale for a prospective buyer, you must have a written agreement in place before showing the property. The Unrepresented Customer Showing Form (TXR 1508) may be used to satisfy this requirement. If you are showing property for lease or any non-residential property for sale, you are not required to have an agreement in writing. Remember, however, that Article 9 of the NAR Code of Ethics states that whenever possible all agreements should be put in writing. Therefore, it is still recommended to have written agreements in place for all transaction types even though the law only requires written agreements for residential sales.
