According to home inspection standards, which of the following is a concern for inspectors?

In home inspection standards, inspectors are primarily concerned with visible conditions because their role is to assess the current state of a property and identify any observable issues that could affect its integrity or safety. Inspectors examine various components of a home, such as the roof, foundation, plumbing, and electrical systems, looking for signs of wear, damage, or malfunction. The visible conditions uncovered during an inspection can provide crucial insights into the overall condition of the property and inform buyers or owners about potential repairs or maintenance they may need to address.

The other options—warranty of materials, cause of issues, and availability of resources—are more about factors that could relate to the property rather than what inspectors directly evaluate during their inspections. While understanding the cause of issues is helpful for further analysis or repairs, inspectors typically do not diagnose underlying problems; they report on what they can see. Similarly, the warranty of materials falls outside the scope of inspection standards, as inspectors do not guarantee or evaluate warranties. Lastly, while the availability of resources (like repair services or replacement parts) is important for homeowners, it is not a direct concern of the inspector's evaluation of the property's current condition.
