Staging is for ALL the senses. Quote me: “If you can smell it, you can’t sell it.” And this includes “positive” odors because the human olfactory system is so strongly tied to emotional reactions.
You might assume that the odor of freshly baked cookies evokes a “smells-like-home-so-show-me-where-to-sign” response in buyers. But your cash-toting multi-millionaire millennial may, in fact, have an aversion to cinnamon or vanilla or any of Mrs. Meyer’s nasal-raiding fragrances. Better to keep it clean and neutral.
