It took me a long time to go through my mother's stuff after she died. My spouse helped me tremendously, and we wanted people to use the stuff. We wanted to minimize stuff going to trash. Fortunately, there was a goodwill type place at a church one block away so we used a shopping cart to bring stuff there. Some things went to recycling, of course. Nearly no one would take books, though we found one library, very far away, that accepted some donations. We were able to find takers for furniture though it took a long time. We paid rent on her place while doing this work, and of course, that hurt, on top of all the other pain we felt.

So as with other things, you're looking at a trade-off between time and money. If you're hoping to get money for the estate (the people inheriting the remains), it takes more time and effort. If you want to get it done, you can hire one of those liquidators who offers an insulting amount of money and hauls away everything you offer.

I'm not sure if this addresses your question which seems a bit vague.
