I just took care of one of these for someone. I can tell you it's a pain for all involved. I made nothing for taking care of this for someone I barely knew.
I can tell you I was pressured by the spouse to sell everything quickly as this was her most important criteria since she had to move within a couple weeks. I did that. The return I got on what was there was about 50% of what a deliberate sale might bring over the course of a year. I will not be volunteered for such duty again. It was a thankless task that left the spouse disappointed in what money was garnered and not so thankful to me. More times than not, I've been around these sales where all the appraisals and bluebooks get tossed out the window in favor of getting rid of the whole problem all at once to someone or some business that will make a good swat.
My advice? If you don't give a damn about what burden you leave behind, keep 'em all to the end (assuming you can plan for the BIG event). If you don't want to burden others, start selling off as your usage and health decline in a more deliberate manner. In other words, take care of your own mess. And believe me, it is viewed as a mess more often than you think.
