The home owners I work with are sold on the idea of staging but the idea can be taken to a ridiculous level. I am going to be honest and just say that I don’t know if your home will sell faster and for more money if your couch is against the wall or pulled away from the wall.
In general your home should go on the market clean and in good repair without a lot of clutter or colors that are hard to work with.
Neutral colors on the wall are best so that perspective home buyers can picture the home with their own belongings in it.
Moving a rug or a couple of pieces of furniture may make your home look more appealing to perspective buyers but staging is not an exact science there is more than one staging solution for each room. It is more of an art.
Home sellers who have had their homes on the market for a couple of months should not expect it to sell this week just because they re-staged a room.
In my experience the home owners who are the most concerned with staging sell their homes the fastest probably because they are motivated and usually cooperate with the sales process and are willing to do most anything that will help them sell.
