Toys: store toys in large plastic containers with lids. Stack the containers against the wall in the garage or under a bed.
Shoes: Purchase a small shoe cubby for each door (excluding the front entryway). As you walk into your home, put your shoes in the cubby instead of leaving on the floor.
Kitchen: Is your kitchen a mess? Throw the dirty dishes into the dishwasher and dirty pots and pans into the oven.
Dirty clothes: Clothes are always around. Throw them under the bed. A buyer will not look under your bed!
Bathroom: Ewww! Just clean your bathroom.
