Of course your house is cluttered...you're moving! But it will help the inspector if you make sure there is access to all components - windows, doors, access panels and hatches unlocked. Room to get to electrical panels, water heater, Heat/Air equipment.
Make sure all utilities are on and working - Electric, water, and gas.
Make sure all light fixtures work. Are there bulbs burnt out? Replace them.
When preparing your home for a walk-through or an inspection, of course you want it to smell nice, but don't overdo it! One air freshener in one room should be enough. If there's an air freshener in every room, I always wonder WHAT they're covering up!
For an inspection, it's usually best if animals are out of the house. They can get pretty stressed, and can hinder the inspector. Not to mention that I'd hate to accidentally let your Fido out an open door! If you can't take them out, at least put them in a crate. Remember, the inspector has to get into each and every room, so you can't just close the dogs in a back bedroom.
If your home has some special feature - a hidden room, a door that opens only a certain way... please let the inspector know about it at the start. OR leave a note - it will be GREATLY appreciated.
During an inspection, I will change the thermostat setting to check the Heat and Cooling. Please make sure I have set it back to your preferred setting!
During the inspection, I will turn on and use all appliances. Please double check that the oven is off, oven light is out, and burners are cool.
I will usually use the gate to walk all around the house. Please make sure I remembered to close the gate before you let your pets out!
