Most of the time just load everything in the trailer (huge enclosed trailer). Get it home home and park it next to the dump trailer. Sort box by box and make piles, trash and unsellable stuff goes right in the dump trailer, obvious stuff of value is pretty much photographed and listed where appropriate as it is uncovered (Craigslist, Ebay, Amazon), questionable stuff is piled up to research later, flea market / garage sale stuff is boxed up and stored until the next garage sale, and give away stuff is boxed and either taken directly to Goodwill or we have a person we can call who will come haul it away to sell. We also call that same person at the end of the day after a garage sale and give him all the leftovers. We do not attempt to garage sale anything more than once. Oh, and there's usually a recycle pile also. Used to try to sell brass stuff at garage sales (candlesticks etc), now they pretty much all go in the recycle boxes.
