You don't want someone finding that something is seriously wrong when you're selling your home. A home inspection report outlines the main systems in the house, which includes the central air conditioning and heating systems. It will also provide information on the interior plumbing and electrical systems. It will also outline any visible insulation, walls, and ceilings, as well as the foundation and other structural elements of the house.
Depending on the inspector, they may also identify smaller issues that you aren't aware of. While minor problems can be addressed quickly, larger problems could prove to be a deal-breaker. A home inspector can help to identify these issues prior to you make an offer. If the issue is so critical that you cannot afford to wait for the seller to fix it, consider hiring a professional home inspector or real estate agent to help you make the right choice.
Although there's no requirement that you have to attend the inspection it is a good idea to observe the inspector while the process is underway. Being present can ask questions regarding the condition of various areas of the home and the system in question. You will be able to know what the inspector is looking for and the reason why it is crucial. You'll be able to understand the written report after the inspection. It's a good idea for an inspector to have a good reputation, high levels of training, as well as a wealth of experience.
