It might be grim but I wonder if you could setup a system where people bid on the contents of a home..... digging through a stranger's things could be an interesting, even if morbid thing.
But when we bought a house with contents, sold by the estate, that was just plain grim. They had no children, and a distant relative had inherited. They first held an estate sale, for the most valuable stuff. And we got the rest. With price tags :(
But damn. Clothes. Personal papers. Photos. Home movies. It was overwhelming. But much of that, I admit, was projection. In that I have no children, either ;)
And all to the trash I assume?
I have a goal to not leave anything like that behind, if future people aren't going to want it, I shouldn't be keeping it in the first place.
I'm failing utterly in doing it, but it's a goal.
I did keep some stuff. That old pair of scissors that I've mentioned. Some antique tools.
