I’ve never met a home that didn’t need staging on some level. Search similar homes for sale in your area. (Comps)
If even one of your competitors is beautifully staged, yours needs staging to compete and draw those buyers. If none of them have been staged, you need staging to stand out from the crowd. Vacant homes need staging because empty rooms leave nothing for buyers to look at except the flaws. Even newly remodeled, vacant homes need staging to show the buyer scale and help them visualize how they will live in the home.
