The average home inspection takes around 2.5 hours to complete. That’s because the inspector goes over every last detail to provide an accurate assessment of the home’s condition. The home's size and features will factor into the length of the process and what the inspector makes a note of. While the chances are slim that they’ll write about every last nail in the home, you can expect explicit details about switches, sockets, walls, and so on. You want to make sure you read through all of those details and discuss them with the agents and anyone else involved in the transaction.
