First of all, the refrigerator or information board take your pick. Usually this huge magnetic space if covered with PATT memo's, shopping list, hand draw art, and tacky moose magnets. The top of the fridge is usually the catch all for cereal boxes, bread, and dusty baskets......get rid of it all. This screams to potential homeowners, WE HAVE NO STORAGE!!!!!! The solution clean off the top of the fridge and try using a decorative table runner and as runner for the fridge. They come in a variety of textures and prints and while it hangs down on either side of the fridge it can hide those paper work schedules, school lunch menu's, and PATT memos.
A clean kitchen speaks volumes, when you are about to show your home....do your dishes, please. I don't think there is ever a good place for a cat box, but I'm pretty sure its a turn-off in a kitchen. Cleaning off the the counter and places perhaps a glass bowl of lemons or now that we are approaching fall some pumpkins or apples. The buyer need to be able to envision themselves there, hard to do if they can't get past all the unnecessary stuff. In the meantime, I know you still have to live...but its kind of nice living clutter free.
