You don't want anyone to find that something is seriously wrong when you're selling your home. A home inspection report will outline the major systems within the home, such as heating and central air conditioning. It will also include details on the interior plumbing and electrical systems. It will also describe any visible insulation, walls, or ceilings and the foundation and other structural components of the house.
Depending on the inspector's findings, you may be unaware of small issues. While minor issues can be fixed quickly however, more significant issues could turn out to be a deal-breaker. A home inspector can help you to identify these issues prior to you make an offer. You should hire an expert home inspector to help make a decision when the issue is too significant to let repairs be made by the seller.
While you don't need to be present for the inspection, it's a good idea. If you're present, you can ask questions about the state of different parts of the home and the system at issue. You'll also be able to understand what the inspector is looking at and the reason why it is important. After the inspection, you'll be able to understand the written report. It's best to select an inspector who has an established reputation and a good level of education and experience.
