We sold a lot of stuff, gave a lot to our kids and places like the Salvation Army.
We did not follow the advice of many about getting rid of everything and put quite a bit in storage (10 by 30 storage unit).
After 11 years of full timing we bought a house in western CO and had all of our stuff moved here from NH. We had sold all of the big appliances and most of the soft furniture but still had a lot of stuff.
I am sure glad we did not follow the conventional advice and get rid of all of it.
We have spent about $15,000 buying what we need for the house - stuff that we sold for maybe 10 percent of what it cost back then.
If we had to replace what we had stored - like guns, complete woodworking shop, my wifes equipment for building miniatures, her genealogy research records and small appliances, desks and office equipment, and my electronic gear, it would have cost a lot more than what we spent for storage.
Some things like heirlooms that came from as far back as our great grand parents could not be replaced at any cost.
