I
II am so sorry for your loss and know this must be a very difficult time for you. Since your grandson is hiring one of the individuals who specialize in estate sales, you should have him check with them before you invest a lot of time in labeling and organizing things for the sale as most of the time they do this as part of their service. When my friend had hers after the death of her DH, she just picked out the items she wanted to keep for her self or family members and they took care of the everything else related to the sale.
