What must sellers disclose under the Illinois residential real property disclosure act?

Under the Illinois Residential Real Property Disclosure Act, sellers are required to disclose various pertinent details about the property they are selling. One of the key obligations is to inform potential buyers of any material defects in the property as well as their occupancy status. The requirement for sellers to disclose that they have occupied the property in the last 12 months serves to provide transparency and insight into the property's history and condition.

This disclosure is important because it can affect the perception of the property's livability and may influence the buyer's decision. Understanding the previous usage of the property can alert buyers to potential issues that may arise from occupancy, such as maintenance needs, localized wear and tear, or even evidence of problems like pest infestations that may become apparent with recent use.

The other options pertain to circumstances that may not be required disclosures under Illinois law. For instance, while some conditions might be relevant or concerning, they do not fall under the enforceable obligations established by the act regarding the condition and occupancy of the property.
