Staging makes the home look much better if done right. I was once told by a mega agent that he tells is clients the day you sign a listing contract with me is the day you no longer live here. His team will go in and remove all personal items, photo, junk, and even clean up the garage so it look more open and larger then life. I think as humans we tend to collect lots of things and gather them up in our home. I do this myself. You want buyers to walk into the home and be able to picture their family living in that home. If they are bumping into tables, chairs and looking at the home owners pictures of his kids on vacation, it tends to be a little hard to picture anything but clutter. So to answer your question I say yes staging is important in most cases to sell your listings.
