With that level of supply, buyers can afford to be selective, so presentation becomes a differentiator rather than a nice extra. Decluttering, depersonalizing, and arranging existing furniture to show scale and flow accomplish most of what full staging does, at a fraction of the cost.
Full staging tends to earn its cost back on a vacant home or one with awkward, hard-to-read room layouts, where empty or oddly furnished rooms photograph poorly and leave buyers guessing at scale. A lived-in, well-kept home usually needs light staging rather than a full furniture swap.
What your specific home needs depends on its condition and how it currently shows. Get your hand-reviewed valuation from Joel Dyck.
