My mother is a hoarder. The last time I helped her move it took 3 of U-Haul's largest trucks to transport everything. She actually keeps her home fairly clean but boxes slowly build up over time then she deposits them into a storage unit. By my calculations she's spent about $20K over the last 6 years just to pay for the storage unit. This is also in conjunction with a shopping addiction. She has no money saved up and frequently tells me she can't buy groceries despite constantly shopping online and paying the storage unit fee.
She is going to have to move again soon and I am not going to be the only one to have to transport all that crap, possibly to another state. So my plan is that I'm going to sell all of it.
So I have decided that I'm going to start selling her stuff. I have access to the storage unit and I have told her what I intend to do, she is reluctant but almost sound like she's be relieved if I do.
So my question is; how do you deal with someone that has a bad shopping/hoarding addiction and what method should I use to sell her hoard? Not sure if I should do it online or just have a yard sale.

Stuff: Compulsive Hoarding and the Meaning of Things
Book by Gail Steketee and Randy O. Frost

My mom was also a hoarder anon. Best of luck to you. This book helped me understand the pathology behind it.
It is a mental illness.

Recommend you understand it’s possible for her to relapse and for this to be cyclical. It’ll be a frustrating, painful road.

If you truly think there are items of value sell em. But easiest and fast route is to toss it all or donate what you can in large quantities.

Again best of luck.

Unless you take financial control over her money and donate/trash/estate sale everything, it'll never stop.

I didn't live in a clean functional house until my father died. Was the only way to stop him from hoarding more tradh
