You don't want anyone to find out something is seriously wrong when you're selling your house. A home inspection report will detail the major systems within the home, such as central air conditioning and heating. It will also provide information about the plumbing system inside and electrical systems. It will outline any visible insulation, walls, and ceilings, as well as the foundation and other structural elements of the house.
Depending on the inspector's findings, they may be able to spot smaller issues you may not be aware of. Small issues won't be addressed in a hurry, but more serious issues could be the reason for a sale. Before you offer, a house inspector can help you determine any problems. You should hire an experienced home inspector to help you decide when the issue is too severe to be left to be done by the seller.
Although you don't have to be present for the inspection, it's a good idea. By being present, you can ask questions about the state of different parts of the house and the system at issue. You'll also be able to understand what the inspector is seeing and the reason why it's important. After the inspection, you'll be able to understand the written report. It is a good idea for an inspector to have a solid reputation, a high level of education, and a lot of experience.
