Let’s assume you’re selling a vacant house. If a buyer walks into your house, the house will seem cold and uninviting, and buyers will feel no emotional connection. The only thing a buyer will notice is empty walls and dull floors. There’s nothing to be excited about there.
On the other hand, when a buyer walks into a furnished house, he’ll feel welcomed and much more comfortable. It will also be easier for the buyer to picture living there. That is one of the reasons people stage their houses. If the buyer can’t imagine living there, the sale is going to be a failure.
