A 4 point inspection looks at the 4 major systems (Roof, Electrical, Plumbing, HVAC) in an older home. An insurance company wants to know that an older home has been well maintained, and the major systems are in good working condition. This is not a safety inspection. They are done by a licensed inspector or building contractor.
Here is what a 4 point inspection looks at:
Some insurance companies like Citizens Insurance, require the inspector to use their form. Other insurance companies allow the inspector to use their preferred format. In addition to the written report, the inspector will take photos of each of the major systems to provide to the insurance company.
