I've been sending things to auction for the past 2 months. The advantages are that I don't have to handle (whatever) again and we get a little $ back. (It's all going against debt.)
I have sent items to two different household/antique auction houses and a book auction house. There are definite holes in the stored stuff now, a bit less debt and I have a bit more time.
My new goal is to 1) Finish cleaning out/culling the attic (last big piece of furniture was in there) and then 2) close the storage.
I am psyched! This works, it doesn't push on my PTSD, we have more room, less debt and I have less stress. I do still. have an antique booth and donate some of what doesn't sell right away to my favorite thrift shop, which had been my strategy before. But the auction means I can just get rid of piles of things instead of a few here and there.
