You don't want anyone to find out something is seriously wrong when you're selling your home. A home inspection report will describe the major systems of the home, including central air conditioning and heating systems. It also outlines the plumbing and electrical systems. It will outline any visible insulation, walls, and ceilings as well as the foundation and other structural components of the house.
Depending on the inspector, they may also identify smaller issues that you aren't aware of. While minor problems can be fixed quickly, larger problems could prove to be a major factor. A home inspector can help identify these things before you make an offer. You should seek out an experienced home inspector to help make a decision if the problem is too serious to wait for repairs to be made by the seller.
Although there's no requirement that you must attend the inspection, it's an ideal idea to be observant of the inspector while the process is in progress. Being present can ask questions about the state of different parts of the home and the system that's being examined. You will also be able to understand what the inspector is looking at and why it's crucial. You'll be able to understand the written report after the inspection. It's a good idea select an inspector who has an established reputation and a high degree of education and experience.
