Property: If you have extensive property or outbuildings, digging a path that at least shows most of the property and allows safe access to any structures or notable features will definitely be a good idea. Make sure that the path is wide enough to accommodate an average person walking normally. The less stress your buyers have about actually getting around, the more positive of an impression your home makes.
Put attractive looking welcome mats on both sides of the door to help minimize mess and drips. Make sure there is adequate accommodation for coats, hats and other belongings that need a temporary home while the tour is being conducted.
While you don't want your MLS pictures to be dated by seasonal decorations, it is totally fine to use them in your house when you're staging it for sale. Try to keep your decorating fairly neutral and simple so that prospective buyers can easily see themselves in your space. Don't let your holiday decorations obscure your home's assets either, they should just add a touch of the holidays without being overpowering.
