I'll never have a big enough or nice enough house to display everything I want to. (And that's not due to paying too much to collect - it's because I had the stupid luck of buying a house, alone, in 2012 before the market reversed. My mortgage is half of what rent is in my city and so I'm in the beneficial position of it being stupid to sell because I'll never get a better deal in this lifetime.)
Ooooooh, man! This is me, in a nutshell. My first wife and I bought a house in 2006, first time buyers, got an incredible rate and it was in a small community so the price of the home and land it's on was a steal (I got the house in the divorce). My mortgage is $500/month, and that is something that I will never, ever, find anywhere else 20 years after the fact. The low cost of my mortgage has enabled me and my family to live very comfortably in the years since, and since this is a thread about quitting and hoarding and selling I guess I would say that I've been perhaps a bit
too comfortable lol
Growing up, I had a lot of toys but they were usually yard sale toys because we didn't have a ton of money. I would get new toys at Christmas and for my birthday, so I didn't have a ton of "really nice" stuff. Add in that I was undiagnosed autistic child. Fast forward to my late 30's (I'm 42 now), still undiagnosed, but McFarlane Toys puts out wave 1 of their new DC line. I remembered McFarlane from the 90's, so I bought every figure on a whim to check them out. Instantly hooked. For the first 3 years, I was a completionist with DC - I bought everything McFarlane put out. I had also expanded things into Neca (Predators, TMNT), Mafex, Mezco, etc. By the time I was 40 I was also into Hot Toys and 3rd Party 1/6 scale stuff in addition to the 1/12 stuff. My basement became full of things, my display area was overrun. Boxes everywhere, stacks of things everywhere, and so much crap piled up that nothing was ever actually on display. At 42, I know now that I'm autistic, and I know that my overboard purchase habits the last 5 years is due in large part to "filling that hole" that child-me had from not having nice things. Knowing these things, and how autism can affect things like this (with the laser focusing and habits that come with it), have helped me in a way to make a plan to deal with it. I have sold things on ebay, which is a pain sometimes, but recently I had a buyer try to scam me out of a $400 Hot Toy purchase so I'm taking a break from the platform.
One thing you could try, if you're in the market to sell, is to check your areas for local toy shows that accept new vendors. I became a vendor at a semi-large toy show last year in May, and they had another show in November, and I'm averaging about a thousand dollars from each show. I sell boxed items and loose items, and I put out a $5 bin and a $1 bin. The bins drive people in, and then they end up buying the more expensive stuff later. It's fun to interact with toy collectors, and I don't advertise it but everyone who stops at my booth gets a deal on top of the prices. I've never told someone "no" when they've tried to haggle. It's a good time, and you can make some easy cash. I personally sell things to create space, I'm not in it to recoup costs, so while I'm not giving things away for nothing I'm not necessarily putting market prices on things (I sold a Mezco One:12 to a lady at the last one who came by 3 times to look at it...she didn't have the $80 that it was marked for, but on her 3rd visit I told her she could have it for $40. The look on her face was worth the loss). If you are in it to recoup your costs, then that's different, but if you're in it just to pare things down and have a good time, perhaps make someone's day, try a local toy show. My next show is May 10th, and I have 3 tables this time (the max here is 3). Currently sorting and pricing up a storm.
Sorry for the long post. It's my autism speaking, I annoy people at work with verbose emails all the time lol
