Plan on attending the inspection, as the report will make more sense if you were there as the concerns were found and documented.
 

A normal home inspection usually takes at least two hours, and may last as much as five hours.
This will vary depending on the type of house, it's size, age, condition and whether the house is occupied or vacant.
 

Ensure that access/entry is available to the inspection property, including the attic and crawl spaces, and that no personal possessions block important areas and components.
 

Verify that all utilities, systems, and appliances are on and functioning. This includes water, electricity, gas, furnaces and air conditioning systems.  Copies of any service records or ongoing service agreements for systems and components would be helpful.
 

Understand what a home inspection is and is not. Therefore there will be less chance of misunderstandings during and after the inspection.
 

Take notes on items that are beyond the scope of the inspection, such as regular maintenance and cosmetic items.
