Which of the following defines a material defect?

A material defect is a significant issue in a property that affects its value, safety, or habitability and consequently would impact a buyer's or seller's decision regarding the transaction. This means that if a defect is material, it is essential enough to influence how a party views the property, often leading them to reconsider their willingness to buy or sell at a certain price.

Examples of material defects include problems with the roof, foundation issues, or significant plumbing problems, as they directly affect the property's overall function and viability. Understanding material defects is crucial for individuals in real estate, as they play a crucial role in disclosures and negotiations, ensuring that parties are adequately informed about the condition of the property involved in the transaction.

The other options describe issues that, while they may be relevant, do not rise to the level of a material defect. A trivial issue does not significantly affect the property; an aesthetically unpleasing feature is more about subjective tastes; and matters of personal preference are typically related to individual likes and dislikes rather than critical aspects that would influence a financial decision.
