Short answer
Decide what stays, mark it clearly, set aside items for donation or sale, then schedule removal of everything else in one or two visits priced by volume.
Sort in three groups
- Keep
- Sell or donate
- Remove
Mark what stays
Painter's tape or an empty room for keep items prevents mistakes.
Final walkthrough
Walk each room with the crew lead before loading and again before they leave.
Room-by-room order
Start with the garage and attic so the crew has staging space, then work through bedrooms and living areas, and finish with the kitchen and closets. This keeps paths clear and avoids moving the same items twice.
Keep, donate, discard
Set three labeled areas before cleanout day. Anything not marked keep is assumed to go, so confirm the plan with every family member involved.
