I would suggest taking down some of the photos, trophys, do-dads, knick-knacks, what-nots, collectables, and any other items that could be a distraction to potential buyers.
I show houses routinely with so many grandkid photos, sports trophys, collections of whatever, etc. that buyers get distracted admiring people's "stuff" and forget they're there to look at the house.
You can visit my website:

In my experience the more of these items you do the faster your home will sell and for more money in your pocket.
