Your state's seller condition disclosure
This is the form where you describe what you know about the home — roof, water, sewer/septic, structure, systems, environmental issues. It is a disclosure of what you know, not a warranty. In Indiana, State Form 46234 generally has to reach the buyer before you accept an offer. In Kentucky, KREC Form 402 is the official form and OwnerRoute uses it as the default. Answer honestly, and update an answer in writing if something changes before closing.
