I am very sorry for your loss and the heavy emotional toll it takes. My husband I went through this a number of years ago. We went through everything, thought hard about we wished to keep and gave that opportunity to other family members and friends. When we felt sure we had finished that step we contacted a local estate sale company who charges a flat % of everything they can then sell. They come into the house, organize the contents for sale after researching any antiques, collectible etc. This company had over 5000 followers online in our rural, small town region. You can be there, or not the day of the sale, as you wish. At end of sale they keep 20-30% of the total and the family receives the rest. They advertise long before items for sake. They dispose of items that don’t sell, with us able to pre designate our choices for disposable. It was a blessing for us to be able handle it this way. We kept what we wished and the rest went to others who who could use it or wished it. It let us focus on healing rather than estate details.
