It’s fun to stage a house when the homeowners already has most of the ‘good’ stuff to work with. Sometimes they just need a little tweaking, a new paint colour and some help with furniture placement.
When you have neutral colours on the walls then you can play with bold accent colours because buyers will realize that the accessories aren’t staying and the house is move-in ready.
Adding the colours through accessories also helps buyers remember your house when they are looking through hundreds of pictures on MLS. You want your house to stand out!
