Having worked with dozens of vacant and semi-vacant properties for sale over the years, we've learned a LOT of things, including:
Contrary to what many people believe, most buyers cannot mentally visualize their "stuff" in an empty room. That's why developers furnish their models!
Staging small spaces is as important as filling larger ones. For instance, often buyers cannot image a queen sized bed in a townhome's master bedroom, let alone night tables, dressers, etc. Experienced stagers know what realistically can be placed in a room to best utilize the space without overcrowding it.
