Its a murderous job. Just recently helped my wife with her mom and dad's estate. Had pickers come in, had yard/estate sales and put some items on ebay. For example, sold a '90s Troy-Bilt 'Horse' tiller in like-new shape, running and new battery for $450 but it was worth much more - just couldn't get any good offers.
After this, we came to the mutual decision that starting now we will reduce clutter so our survivors will not have to wade through tons of JUNK that nobody wants. Keeping china and silverware for the grandkids? Get a clue - nobody wants your old stuff, your parents' stuff and your grandparents' stuff! Yes, legitimate antiques in excellent condition with provenance can raise money, along with any Sterling silver, real jewelry, etc., but the run-of-the-mill 'keepsakes', like depression glass, are simply not worth trying to sell. We took $1000 for a 130 yr old 'Persian' rug that was cleaned, treated and rolled in TYVEK and came with an appraisal of $10,000, and felt lucky to get that.
Tools, equipment, new spare parts, etc., are in a different category but be prepared to take junk prices for it. Right now, the biggest problem is COVID because you really can't have a yard sale in most areas. You may be stuck with it for a few months. If you have one of those outdoor 'permanent flea markets' in your area where you rent tables, and you have the time for it, you might consider taking a truckload of stuff up there every weekend until you get down to what you're going to take to the dump. Its one of the best ways to go because in normal times you have thousands of people walking past your table, and nothing sells like setting eyes on the stuff. Its just a ton of work, and if you are over 60 it can get old real fast.
