I feel your pain, OP! My mother passed away unexpectedly last month, and thanks to useless siblings (one of each) I’m the one tasked with spending my nights and weekends going through, sorting out all the stuff in her enormous UES co-op. She had lived in the place since 1961 - it was a wedding present from my father’s parents - so while it doesn’t quite resemble the Collier brothers townhouse, there really is so, so much stuff! It really is overwhelming.
I’d say a good 50% is assorted paperwork (tax returns, bank statements, brokerage statements, bills of sale, letters, our school reports, cards, etc., etc.), 30% is pictures, and the rest is a jumble of clippings, magazines, religious stuff, day planners, and the like. Mind you, that’s only the stuff in drawers, in boxes in closets, under beds - basically the hidden stuff.
Then there’s the clothes - 2 huge walk-in closets full - the coats and furs, the furniture, the books, the china and silver services, the stemware, the crystal, the knickknacks, the kitchen things, etc.. I don’t even want to think of what awaits me in the 2 storage units in the basement that come with the co-op.
My advice OP would be set smallish goals for the day or the week. Like “today I will get all the clothes bagged up for X to pick up” or “this week I will go through everything in the bedrooms”, things like this. It tough and tedious, but I’ve found doing it this has helped.
I also will echo what others have said about going through things before tossing or donating. Not just books either! I have already found a couple of thousand dollars in wallets and handbags she had received as gifts through the years, still in their boxes with the cards - I do remember my mother saying it was bad luck to give a wallet or handbag as a gift without putting some money in it. As most of these were gifts from her lady friends, and they were all fairly well heeled UES ladies of a certain age, most had a hundred dollar bill in them.
Tomorrow I’ll be bagging up all the linens in the place (sheets, blankets, towels) to be donated to an order of nuns for use in their rest home. Wednesday I’m taking off work as a friend who works at Christie’s is coming over with 2 colleagues to go through the jewelry, art, furnishings and such to give me an idea of value. I doubt the furniture will be worth much - it’s all solid wood, in near perfect shape, but tastes change. I am curious about the jewelry though - she had some very nice pieces plus a bunch inherited from various aunts and great aunts - some of those pieces are well over 100 years old, so we shall see.
I honestly think it will take me until May or June to finish up, and have everything either tossed, given away, donated, or kept. Then I’ll figure out what to do with her place.
Finally OP - do take some down time for yourself while you’re doing all this. It can be very emotionally draining - especially if it’s the place you grew up in. You need to recharge with some fun during this process. Take this Wednesday for example - once my friend and his colleagues are done, a very good friends with whom I share benefits will be coming over for some play. A fellow does have to eat, after all!
