A 6-month downsizing timeline, counted back from moving day

A downsizing move is two jobs at once: an ordinary house move, and the slow work of deciding what to do with half of what you own. The second job is the one that runs late. Movers can load a house in a day. Nobody can sort thirty years of belongings in a week.

So plan backwards. Put moving day on a calendar, then give each month before it one main job. If you do not have a firm date yet, pick a target month and work to that. A plan with a soft date still beats no plan.

Six months out: decide what the new home will hold

You cannot sort well until you know what you are sorting for.

Get the floor plan, or the closest thing to it. Room sizes, closet count, whether there is a garage, a basement or outdoor storage. If you have not chosen a home yet, write down the size and type you are aiming for.
Walk your current house with a notebook. List the large furniture room by room. Mark each piece as coming, not coming or undecided.
Tell the family. Grown children need to hear the plan now, not in month five. If their belongings are still in your house, give them a deadline in writing and set it for about three months before the move.
Start the easy rooms. Bathrooms, the linen closet and the utility spaces need no floor plan. Sort in an order that starts with easy decisions and you will have momentum before the hard rooms.

If you are still unsure whether to move at all, settle that first. These seven questions are a quicker way to find out than six months of half-hearted packing.

Five months out: sort the high-volume spaces

This is the month for the kitchen, the garage, the shed and the basement. They hold the most items and the least sentiment, so they reward steady work.

Set up a way for things to leave. Find your donation center’s drop-off hours and what it will not accept. Ask your town or county how it handles bulk pickup and hazardous waste such as paint, fuel and chemicals.
Fix a weekly clearing day. Sorted piles that sit in the hallway drift back into cupboards.
Start a list of things to sell. Do not sell yet. Just note the pieces worth the effort.

Four months out: furniture and the things that sell slowly

Large furniture takes the longest to rehome, so it goes early.

Measure what you plan to keep against the new rooms, including doorways, stairs and elevators. A sofa that fits the living room is no use if it cannot get there.
Offer the rest to family first, with a date by which it has to be collected.
List what you are selling. Big pieces can take weeks to find a buyer. Decide now what you will do with anything that has not sold a month before the move, so you are not negotiating over a dining table in the final week.
Sort the spare bedrooms and closets.

If you are also selling the house, this is a sensible point to ask your real estate agent what they need from you and when. Their schedule may move some of these jobs earlier.

Three months out: book the help

By now you know roughly how much is coming with you, which is what a mover needs in order to give an estimate.

Get written estimates from more than one moving company. Ask each to look at the house in person or by video, and ask what is and is not included: packing, stairs, long carries, storage, insurance.
Book any other help you need. An organizer, a senior move manager, a clear-out service for the garage, a cleaner for after you leave.
Check the rules at the new place. Condos and communities often have set moving hours, elevator bookings and parking limits for trucks.
Hold the children’s deadline. Whatever is still unclaimed gets donated or discarded as you said it would. Set aside anything that looks valuable first, and get a clear answer about it before it leaves the house.

Two months out: the sentimental sort

Photographs, letters and keepsakes come last on purpose. With the rest of the house done, you can see how much space you really have for them.

Set a container limit per person and choose the best, not everything.
Scan or photograph what you want to remember but not store.
Begin packing what you will not need before the move: out-of-season clothes, books, framed pictures, the good dishes.
Start a moving folder. Estimates, contracts, the new floor plan, and a running list of every company and office that has your address.

One month out: paperwork and packing

Work through the address list. Mail forwarding, bank and card companies, insurers, your doctors and pharmacy, pension or benefits offices, subscriptions, voter and vehicle registration.
Arrange utilities at both ends. A stop date at the old house, a start date at the new one, and internet installation, which often has the longest wait.
Confirm the mover in writing: date, arrival time, addresses and the inventory.
Pack room by room and label each box with the room it is going to, not the room it came from.
Make one last donation run and book a final bulk pickup.

The final week

Pack a box or suitcase that travels with you: medicines, chargers, documents, a few days of clothes, basic kitchen things, bedding and towels.
Keep valuables, important papers and anything irreplaceable in your own car.
Empty and defrost the freezer, and run down the pantry.
Walk every room, closet, cupboard and the attic once the truck is loaded.

If you have less than six months

Keep the order and shorten the stages. The order is what matters: know the space, clear the easy volume, deal with furniture, book help, then finish with the keepsakes.

If time is very short, spend your own hours on the decisions only you can make, and pay or ask for help with everything else. A clear-out crew can empty a garage. Nobody else can choose which photographs you keep.
