This type of inspection is done, similar to the one you likely had done when you bought the home. This is an investigation to look for issues that you might not even know are a problem yet. Many people look at these inspections as preventative insurance to catch problems before they become something more costly or significant.
An inspector will look for wear and tear, cracking and leaks, appliance and mechanical issues, and so much more. This will give you a chance to ask more questions about some of the unknowns or get some confidence around how your home is withstanding the test of time.
