To properly prepare your home for a home inspection you will want to repair any damage to steps and walkways and declutter around the front door. Make sure your doorbell works and make sure all of your window locks and seals are in good working condition. Replace any missing shingles and arrange to have your furnace and central air conditioning serviced prior to inspection. Fix leaky faucets and fixtures and repair grout around tubes and sinks. If the home has battery operated smoke detectors, put in fresh batteries and test prior to inspection.
You will need to allow approximately 3 hours for the inspection. Do not plan on being there when the inspector is there. Make sure the inspector has full access to any and all locked areas. If you have pets make sure that your pet goes with you or you have them properly crated. It is also a good idea to have valuable and medications locked out of sight for peace of mind.
