Setting the stage to position a home for sale or staging is a smart marketing move when it’s time to move a home in just about any kind of market. Home staging is to the interior of a home what curb appeal is to the exterior — nipping and tucking, furnishing and accessorizing, buffing and polishing until the place looks like a model home, without being clinical. But it can also include curb appeal. With just the right special effects, the effort can transform a home into a house of dreams and help potential buyers visualize potential. Done wrong and a home can become more like the set of a horror movie.
