In most cases, professional home inspectors stay busy. For example: if you needed to see you doctor, you would call their office and schedule an appointment for a week or two out. There is generally no problem with this. If you have an emergency, then we are either going to call an ambulance or take you to the emergency room. Home inspectors are considered professional people and most of us stay busy, meaning that we book up 4 to 5 days in advance.
Remember, this is the single largest investment you are about to make, and you don’t want to be rushed. Having 10 days for “Due Diligence” allows you to get the home inspection and call in any other professional (electrician, HVAC contractor, plumber, or structural engineer etc.) based on information your inspector has provided to you.
