Sometimes, but mostly I find a lot of objects that don't belong in the main living areas. It's surprising what people will put up with. It would make a person if gloomy if she didn't already know she has excellent taste, herself. We show basements, especially if the buyer needs space for lots of awful, ugly, mismatched things. That's a fallacy.
Nobody wants to buy a home full of other people's belongings.
But you come in and fill the house with your own decorating touches, including carpet and furniture and sometimes tile and paint and wallpaper. Those aren't belongings. That's all from my warehouse. Full of Wingback chairs. Fine leather love seats.
