If I were a realtor, I would have a virtual tour of the house showing the empty rooms. Then, if the customer wanted, I could also show the space with AI augmented furniture showing two or three decoration ideas. That nook under the stairs? Show it as a storage area, a study area, a small pantry, a pet station, a home automation rack, etc. The master bathroom? Show it with modern, classic, retro, painted, wallpaper, window treatments, etc. Same with other rooms that might be in the house: den, dinette, dining room, formal living room, game room. A good AI could show suggested settings for multiple locations in the house.
Many new buyers will mentally place their existing furniture in the home but struggle to think what to do with the extra space. One of the biggest selling points for realtors is getting the customer to start imagining themselves in that house.
