When you’re marketing a property for lease that had previous flooding from a property condition, REALTORS® should consider the Code of Ethics.
Keep in mind that Article 2 says REALTORS® should avoid exaggeration, misrepresentation, or concealment of pertinent facts relating to the property or the transaction. Article 12 says REALTORS® should be honest and truthful in their real estate communications and present a true picture in their advertising, marketing, and other representations.
If repairs have been made, the property condition has been resolved, and there are no other known issues from prior flooding on the property, there’s no legal obligation for you to disclose prior flooding from a property condition. If a prospective tenant asks questions about prior flooding, though, you as a REALTOR® should tell the truth.
