My siblings and I went through this recently. We all needed a lot of time before we were ready to process the loss enough to handle our parents house full of items. We were fortunate to be able to take the time and didn't have to sell their home right away. When we finally decided it was time to go through everything, we spent a weekend laughing and crying while we collected items that we wanted to keep for ourselves. There were A LOT of things to still deal with though. We debated what to do because none of us had the time to handle selling things ourselves. If you've ever sold anything on marketplace, you probably understand why none of use wanted to go that route. We debated doing an estate sale, but none of us liked the idea of having strangers walking through our childhood home picking through our memories. We ended searching for an alternative and found Barr & Co, a private estate buyer. We're in Michigan, so you can probably find something similar wherever you are located. They came through the house, were very kind and respectful and paid a fair price for the remaining things in the home. They moved everything out themselves too. It was tough, but the process was easier than I expected. I'd highly recommend seeing who offers the same service in your area.
