He or she will examine all the major elements of the home, such as the roof, structure, exterior siding, interior electrical, interior plumbing, heating and air conditioning. A thorough inspection usually takes 2 to 3 hours, depending on the size and age of the home. At the end of the inspection you will usually receive a written report of the findings.  Whether you are a first time home buyer or an experienced real estate investor, you should always obtain a professional home inspection so you can: Find out what types of systems and components exist in your new home. Determine the condition of the systems and major components of the home. Understand how the systems and structural components of your new home function. Learn how to maintain your new home to improve the enjoyment and value of your home. It's a good idea to accompany the inspector during the home inspection. This is your opportunity to gain knowledge of major systems, appliances and fixtures, to learn maintenance tips, to better understand the items that will be outlined in the written report, and to ask questions of the inspector.
