Along with decluttering, depersonalize your home. Seniors selling their home generally have a lot of photos of loved ones, family portraits, mementos, souvenirs from trips, and all manner of stuff that is of a personal nature and holds personal meaning. It's not that buyers would be offended or put off by your stuff, it's that you want to neutralize your home to allow buyers to imagine themselves in the space and where their stuff would fit. Also, while you're at it, consider emptying out closets and storage spaces. It will make those normally cramped spaces look larger.
