"If you want to sell your house then you list it at the market price and you sell it. If you don't really want to sell then don’t put it on the market. But don't say you want to sell and then set the price so high that you spend the year cleaning up every morning, having people walk through your living room and look in your medicine cabinets and reject you. That’s just painful and expensive." Director of the Paul Milstein Center for Real Estate at Columbia Business School.
